How to Make a Big Batch of Kombucha

von
Unterstützt
Kombucha is a fermented tea beverage popular in Russia, China, and elsewhere.
The culture forms a leathery skin called the "mother" that floats on top.
This week's Instructables TV episode shows how to wrangle the jellyfish-like "Mother" and make Kombucha 5 gallons at a time. This method produces a fizzy carbonated kombucha that tastes very much like hard apple cider.

For background on this bizarre beverage, read Arwen's Making Kombucha Instructable and the Wikipedia Kombucha article. Some confusion arises from the existence of a Japanese kelp tea also called "kombucha".

Back to the blob:
For me it all started when my friend Anne Harley went to Russia, made herself fluent in the language, joined a band of gypsy musicians, and went on tour with them.
Did you know Russian Gypsies have a caste system that dates back to their origins in India?
That was news to me. So was the fact that Kombucha exists. Anne brought a very fine Kombucha culture back with her and taught me how to make it.

Since then I've made hundreds of gallons of Kombucha for my friends and myself. I've done a great deal of experimentation and had some serious mishaps. I've killed the culture several times, coaxed it back when it got out of balance, and had a couple of explosions that splattered kombucha far and wide and could have seriously injured someone.
Between the mistakes, mishaps and disasters, actual Russians and new-age fruitcakes have tasted my Kombucha and told me it's the best they've ever had. I work with my culture until I get it tasting like apple cider. So much so that you'll try to figure out what varieties of apples it's from. But there's really nothing in it but tea, sugar, and a festering mass of microbes.

We'll be going step-by step through the process later, but for reference, here is how to make the sweet tea to be fermented.

Anne's Recipe:
6 tsp tea
6 cups h2o = 1.5 quarts
1 cup sugar

same recipe for 4 gallons
64 tsp tea = 1.3 cups
4 gallons h2o = 64 cups
10.66 cups sugar

same recipe for 5 gallons
Just under 5lbs sugar
5 gallons water
1.5 cups dry tea

Schritt 1: Get a Pound of Tea Leaves

Don't ever use Earl Grey tea. The bergamot in it will injure your culture and you'll need to get a new starter. This has happened to me. Anything with citrus in it is bad.

Buy your tea in Chinatown or an Indian grocery store. I pay between a dollar and four dollars for a pound of tea, which will make two or more 5 gallon batches. I've bought many a 6lb bag of tea, which is very satisfying, walking out with a couple of suitcase-sized bags of tea.

Assam tea, Mamri, or Green tea such as "Special Gunpowder" are safe choices.
"Pu Er" tea smells pretty bad at first but makes good kombucha. (The name Pu Er is actually English, get it? "Poo Air" :) )
Don't risk your whole culture with saffron tea, but it can turn out ok.
Early in the fermentation process you'll be able to clearly taste what type of tea it is, but when the fermentation is more advanced the apple flavors of kombucha will dominate and the flavor of the tea leaf recedes.

Don't use teabags. You'll be shucking them for hours, dealing with lots of teabags and unsure of how strong your tea really is. You'll also not know for sure what's in the teabag, maybe something as bad as Earl Grey.

Here's my giant teabag, which I made from a piece of cotton bed sheet.

Types of Tea that have worked for me:
Assam
Mamri
Green (very slow unless you use some brown sugar)
Jasmine (marginal)
Coffee (eventually it barely tastes like coffee)

Mother-Killers
Earl Grey
Orange Spice
Citrus Anything
Cocoa Mix
Synthetic Fruit Punch

Star likes herbal teas, and has successfully tried:
Peppermint (mother was depressed for a long time, but eventually rallied)
Peppermint-Chamomile
Chamomile-Echinacea

Schritt 2: Brew Much Tea

Warning: The tea MUST COOL before you add the culture. The culture you have has evolved at room temperature. If you put it in warm tea certain species such as lactobacillus will outbreed the others and you'll get a sour kombucha without well developed fruit flavors. Very much like commercial kombucha, which is usually a weak vinegar.

Brew a gallon or two of very strong tea, then dilute it.
Don't boil all five gallons of water. That wastes energy and time and improves nothing.
Put one or two cups of dry tea in the giant teabag, tie it shut and boil it in your biggest pot.
"one OR two cups?" you say? Why not more precision?

The recipe calls for 1.5 cups, but all tea is not the same.
That's okay because large batches like this are much more forgiving of variations than small batches. If you make a gallon or less you must stick exactly to the recipe in order to get a good result:

If you've got a big thermos, you can let it steep there hot as long as you want
You could also use a hay box or make Arwen style sun tea.

Schritt 3: The Giant Teabag Workout

Wring out the giant teabag into your brewing bucket, soak it with water, repeat until you don't feel bad about throwing out or composting such a large amount of used-up tea leaves. That 1.5 cups of dry tea swells up to become quite an impressive mound.

I cut the top off a plastic springwater carboy to make the brewing bucket seen here.
I'm in the process of kneading the last tea-essence out of the teabag.
Actually that's impossible, but you have to give up sometime.

Schritt 4: Coffee Screen Method

You can also skip the teabag.
Throw the leaves right in the water and strain them out afterward.
Here I'm pressure-cooking the tea and then pouring it through a gold screen coffee filter.
This is Mamri tea which stays as little pellets that don't clog the filter. Leaf tea and things with large flakes like "Special Gunpowder" would probably clog the screen and take longer than the big teabag.

I usually soak and pour several times, but it still probably doesn't extract as much tea-stuff as the big teabag method.

Schritt 5: Dilute and Add Sugar

This is fun. Open a new 5 pound bag of sugar and dump most of it in. All except 10 or 15% of it.

White sugar is fine, except green tea ferments very slowly unless you add some brown sugar with the white. Otherwise it will take way too long. Other kinds of tea don't need brown sugar but I usually throw some in anyway. Black tea is just green tea that's been through an oxidation process. That seems to make it easier for the mother to digest.
There's nothing wrong with using just brown sugar except it costs more in the U.S. and the flavor will be a little different. Use whatever sugar gives you the flavor you like.

Add cold water to make it five gallons and mix it all up.
If your batch is bigger than your containers split it into multiple containers as seen here.

While you're at it, open a bottle from your previous batch of fizzy kombucha from the fridge and drink it from a fishbowl with ice as seen here. Ahhh good.

Sweeteners that have been reported to work:
Agave nectar
Pineapple Juice
Honey
Brown Sugar
White Sugar

Schritt 6: Add Mother

When the tea has cooled, add the mother. Try to get a solid layer to float on top. That saves time. I save all my mother and add all of it to the new batch.
It grows by a quarter or half inch with each batch and would soon leave no room for tea, but lots of people ask for starters so it's not a problem. I can get starters from them if I make a mistake and mess up my culture, so I don't need to hold any in reserve.

I like lots of mother working. Some people want to only have a single layer of mother and will split the top surface off with each generation. They call the new layer "the daughter" and use it to brew their next batch. If you do that you'll need to add some liquid kombucha or vinegar to your new batch to make it acidic early on and avoid spoiling.

The mother is porous and vinegary. In the quantities seen in these pictures, it will innoculate the new batch thoroughly and leave no ecological niche for opportunistic foreign organisms.

New mother will grow only at the surface.
If part of the mother sinks, a new skin will grow across the area of exposed liquid at the surface.
In this picture you can see that the old darker colored mother had puddles of liquid on top of it. The new lighter colored areas grew there.

Schritt 7: Cover With Cloth. NO LIDS!!!

Warning: NO LIDS! You must cover the vat with cloth.

If you have a lid over your vat, even a loose one, there will be moist air over the mother. There will be condensation on the lid and sides of the vat above the mother.
Mold will grow there and spread to the mother. The mother will die and possibly break apart.

If you see fuzz on the mother throw it away, clean all your vessels and let them dry out.
Bleach them or leave them in the sun if you want to be really careful.
Be very alert to this. Some types of mold make poisons.
Mold is dangerous, which is to say people have died from it.

The Russians call "the mother" "the mushroom", but there is no actual mushroom, fungus or mold in this complex community.

In my experience with helping people get started, mold is a bigger problem in California than in New England.

If you want to brew in a carboy (big jug with narrow neck, such as spring water vendors use) , you need to cut the top off so it's more like a bucket or vat.
I've seen it attempted in standard carboys and it ends badly, even if the jug is covered with cloth rather than a cap.

This fermentation is complex process controlled by the mother. It's an aerobic process at least on the surface layers, and the vessel should not be sealed or you'll end up with problems.

There will be another anaerobic stage later for those of you who want more fizz.

Schritt 8: Date the Vat

Write the date on the vat. Don't expect to remember how long it's been in there.
I expect this batch to be ready for bottling in 9 days or so.
Variables in how much time it takes are type of tea (green or black), type of sugar (white or brown)
how much mother there is, vitality of mother, temperature (warm makes it not tasty, but it gets not tasty in a hurry).

Schritt 9: Sit Back and Watch the Show

A few days have gone by and good things are happening.
In this photo I've pulled back the cloth for a better view.

A new layer of skin is beginning to form at the surface of the liquid.
Where the old mother touches the surface it will be attached to that.
This layer of skin controls the environment in the vat.

The tea has gotten a little lighter in color and cloudy.
Small bubbles of carbon dioxide are forming in the liquid and under the flaps of mother.
Occasionally they blurp up from under the mother. That's yeast working, making alcohol and acetic acid vinegar.

Some tentacles are starting to form, hanging down from the mother.
I don't know what they are but they seem to make the apple flavor. A very good sign.
The tentacles are structurally very different from the mother.
They look almost like algae and are very weak. They're usually darker than the tea and just vaguely greener.

A dusty layer is appearing on the bottom of the vat. I believe it's largely lactobacillus. It's making lactic acid vinegar. It has the sharp tangy flavor found in yogurt and sauerkraut. It's good for you and should be bottled with the rest. Don't transfer it to the next batch or that flavor will dominate.
The same thing will happen if your vats aren't kept cool enough. To correct a culture that's gone sour and simple, wash the vessels and mother with water. Get some starter from someone who's getting more flavors.

The yeast in the vat gets oxygen it makes sugar into alcohol then acetic acid vinegar.
That acid has a boingy sort of tangyness to it which is different from the sharp straightforward tang of acetic acid.
When it gets less oxygen the yeast makes sugar into alcohol, which in small amounts gives the other flavors a sense of depth and buoyancy. In larger quantities it's just alcohol.

Schritt 10: Apple Tentacles

Here are the tentacles that seem to make an apple taste.
I brewed recently after letting the mothers sleep in their own juice for a long time. There were no tentacles and the k'cha had no apple taste. But a bottle of it tasted very apple-icious a few weeks later. I looked and tentacles had grown in the bottle.

Carbonation bubbles float the tentacles to the surface when you disturb the liquid or pull the mother off. 2nd photo shows what it looks like when it floats to the surface.

Schritt 11: Dusty or Cloudy

The dusty sediment building up at the bottom could be Acetobacter, Lactobacillus, or Yeast.
It's probably a mix of those.
It seems to correspond more with the "straight" sour taste of lactic acid than the "boingy" sour taste of acetic acid.

I try not to transfer this sediment between batches. The flavor seems to be best if these species have to regenerate from the mother. Mostly I look for the tentacles in the previous step, and pay attention to what conditions favor those. Don't let your brew get warm, that favors the sour critters in this sediment rather than the tasty tentacles.

I must have been hasty and transferred this sediment. The bulk of the liquid is clear, not cloudy, so it's a few days away from bottling at least and I wouldn't expect this much sediment from liquid this clear.

Schritt 12: Cloudy Means Ready

This stuff is ready to taste and bottle.
The bubbles mean a somewhat anaerobic environment in the liquid and the yeast is making C02 and a bit of alcohol. That stirs up the sediment and makes it cloudy.

There's a nice growth of tentacles, so it's likely to be tasty!

Schritt 13: Vegan Leather Anyone?

The mother is surprisingly tough and solid like squid.
I tried pretending it was calamari and fried it but it wasn't very good.
Then again my fried calamari isn't very good either. Maybe squid isn't supposed to be fried.

Small chunks of mother can be drunk in kombucha and are really good, like the Chinese "pearl" drinks.
The mother chunks are slightly more tart than the kombucha they inhabit.

To get a really thick and solid mother, just let a batch of kombucha keep fermenting. It'll get really sour and you'll get comments about the smell. You'll ignore the comments because it smells good to you. The longer you wait the more sour and vinegary your kombucha becomes, and the better the mother grows.

I tried drying the mother, it gets much thinner and very tough like parchment or rawhide.
I've read that it's been used to make shoes in wartime, but have been unable to find any more details than that.

Schritt 14: Ready to Drink, but ...

You can start drinking your kombucha now if you want to.
Some people take out a portion to drink every day and replace it with an equal quantity of sweet tea.

That is a traditional method but requires regular habits.

Also I like it more fizzy than it gets in the vat, which means bottling it.

Schritt 15: Look for Bottles

When it's just the way you want it, or rather ALMOST, it's time to put it in bottles.
I say ALMOST because you should bottle it when it's just a little too sweet.
That's so the yeast can make that extra sugar into fizz and just a little alcohol.

Regular PTFE or PET type plastic soda bottles, plastic spring water bottles or anything like that are fine.

I once had fifteen gallons exactly ready for bottling and couldn't find any bottles to put it in.
My friends had found my collection of empty bottles and destroyed them in a fenzy of inventiveness,

So I put it in carboys with rubber glove vapor traps as shown here and let the yeast work while I spammed the institute for empty soda bottles.

You can blend old sour kombucha, young sweet kombucha and water to adjust the flavor when you bottle it.
Set the bottles them aside til they get hard from carbonation.
Put them in the fridge
drink it.

WARNING
If you wait too long to drink it the bottles can explode from excessive carbonation.
They can puff up til the soda bottle is round on the bottom and rings like a bell when you tap it.
Three of mine got like this and blew up at once. They blew the side out of the rubbermaid tub they were in, splattering kombucha all over the ceiling, and making a very loud noise.

This danger is why commercial kombucha can't be as good as the stuff you make yourself.
Commercial bottlers can't be blowing fingers off their customers, putting their eyes out and deafening them by shipping time-bomb beverages.
They have to terminate yeast fermentation in the bottles.
That means high acid, low sugar, or dead culture.

If you do it at home you get to have it all.
Sugar, live culture, carbonation, and a potentially dangerous bottle that could blow up if you don't drink it in time. Don't use glass bottles. Enjoy!!

Schritt 16: Bottling Jug

I cut the top off this waterjug and drilled a hole by the bottom for a plastic spigot.
I pour the new k'cha in here from the brewing vats. If it's too strong i add water.
Be aware that the sweet taste recedes faster than the sour taste as you dilute.

If you lost track of time and your brew got way too sour, you can save it a bit at this step.
You can add water and sugar, or younger sweet brew.
If you add sugar though you'll need to leave it in the bottles longer before it tastes honest.

New sugar will make your teeth hurt just like candy or soda.
After the mother has lived on it for a while, it still tastes sweet, but it won't make your teeth hurt anymore.

I used to screen my brew before bottling, but now I like the chunks and tentacles. Like an Asian "pearl" or "bubble" drink. When this spigot gets clogged by that stuff I just work the lever until the chunk comes through.

Schritt 17: Decant Over-Fizzed K'cha

The bottles will keep fermenting and carbonating until something stops them.
That could be running out of sugar, building up too much alcohol, acetic acid, lactic acid, or exploding.

This is why store-bought kombucha can never be as good as stuff you make yourself. They'd get sued when a forgotten bottle blew up and hurt someone. So they have to make it sour and not sweet. That way fermentation terminates or gets very slow and they can even put it in glass bottles.

I've seen plastic bottles of home brew k'cha puffed up round with no necks or puckers on the bottom. They ring like a bell if you tap them, and it's scary dangerous. Use bomb squad methods to deal with bottles like that. Three of mine once went off in a daisy-chain. They blew the side out of a rubbermaid bin and put dripping splatters all over the ceiling. Bottles like this could cripple, deafen, or blind you.

A more common problem ( opportunity ) is bottles with so much fizz it's hard to open them without champagning k'cha all over the room instead of into a glass.

Here's one way to deal with that. First refrigerate it. Gas solubility is higher in cold water.
Then rapidly open and pour the kombucha into an angled glass. The angled glass and angled bottle present a much larger area surface for the gas to diffuse out. If you set the same bottle vertical, the upper surface is too small and you can get a volcano effect.

If your stuff has too much fizz even for that, we're in the realm of art, devise your own methods.
Freezing is bad. Ice has poor gas solubility and plugs the neck when you open.
Some people like to barely open the cap so a slow hiss of air comes out, too slow for bubbles to erupt. I like to open the cap and instantly squish out the remaining air before the eruption. It's amazing how the bottle re-inflates every time you do that. There can be a huge quantity of gas dissolved in the liquid.

Enjoy your super-delicious fizzy healthy K'cha!

hello friend, thanks for this.
I left my mother with an ex co-worker to take care of while I was away and the boss threw it out, and now for the life of me I can't get my hands on another mother mushroom lady.
Please help?
Could you?
That would be divine.
Thank you, in advance.

Hello! Firstly, thanks for such an awesome tutorial! I have a few questions, if you have a moment.

My background is that I am a beer and meade maker, so I have all of the appropriate equipment for said productions and it is all pretty great quality stuff (glass). I have a 3gal glass carboy that is sitting around not doing anything that I'd like to use to make a batch of k'cha with.

1.) Can I not use it with a standard bubbler on top to allow for gas to escape? I have never noticed condensation forming with the production of beer or meade, so since k'cha requires a cool environment, I don't see how it would produce it with that.

- Or could I use the glass carboy with a coffee filter over the top instead of the bubbler?
- Is it the headspace that makes the difference?

2.) What sugars are considered good to use and in what form?
- Do any of them, like honey, need to be boiled for a certain time period to break the complex sugar bonds for the mother to process, or is it fine just heating it up?
- Can I use a mixture of sugars (namely thinking honey + light brown sugar)?
- If just using honey, what amounts would be suggested?

3.) Does the equipment used need to be sterilized like it does with beer making?

Thanks so much! =(^_^)=

Hi there!

Thanks for your great instructable! Your videos really helped me make my first kombucha. I got the starter culture from a colleague and started with green tea. The taste is really interesting and nothing like the kombucha I bought at our supermarket. The kombucha tastes a little bit like peach, what I didn't expect at all.

I will make the next batch with black tea to see what it tastes like.

Greetings from germany,

I am brewing my 3rd batch of Kombucha and I have some serious concerns. After drinking a ton of the de-facto commercial brand for about 2 months I started having really bad headaches. I have completely stopped, and they have dissipated to some degree, but I've been pondering what happened. I'd like to mention that I own a copy of Alana Pascal's book 'Kombucha - How-To and What It's All About' thought by many to be the definitive book on Kombucha.

My first concern: Mobilization. It is my understanding that Kombucha is very effective at not only helping your liver process toxins much more effectively, but that if you have amassed a good deal of toxins in your system over the years that they can be 'mobilized'. This raises serious concerns for those who might have a sizable quantity of such things as heavy metals like mercury. After being mobilized, they may not be rapidly expelled from your body, as was the case that caused them to build up in the first place, subsequently redistributing in other soft tissue of the body such as the brain. I believe very little is discussed about this the average consumer has no clue just how effective Kombucha can be at mobilizing toxins and super charging your liver. Clearly this is a double edged sword and something that should be regarding in much the same way any sensible person would look at vitamins. Proper dosage is key. It bothers me that commercial products say little about the dangers of over consumption. Given that Kombucha mobilizes so well, it is highly recommended that you DO NOT drink it when pregnant or breastfeeding as the fetus/infant will be subject excessive toxins. It is also discouraged for use by children. I don't want people doing damage to themselves out of ignorance, and I don't want the drink I've grown to enjoy greatly to face regulation or worse.

My second concern: Carbonation and storage. In Alana Pascal's book, she informs that when Kombucha is capped, and anaerobic fermentation occurs, toxic by product is created namely in the form of acetone (think paint thinner or nail polish remover). Acetone is a ketone that is very destructive to the kidneys. She indicates that Kombucha should not be stored capped in the refrigerator for more than an astonishingly conservative 3 days or there is the risk acetone production. This is troubling. Most people will tell you, Kombucha is much more palatable when carbonated. This is where I am uncertain. Small amounts of acetone are present in commercial foods we consume and such trace amounts have been deemed relatively safe. Thinking back, I purchased dozens of bottles of commercially available RAW Kombucha. That means, unpasteurized and while I know there are chemical compounds that can be added which do not kill the culture but prohibit it from continued fermentation, I have serious doubt those would have been used. Of those many bottles, several were near there expiration date, and even more of them when opened exhibited vast over-carbonation. This would seem to indicate that shipping and handling practices during the life of that product did not include continuous refrigeration. Suspecting heavily now that this may have contributed greatly to my headaches. To pasteurize or not to pasteurize. Many of the health benefits remain after pasteurization but it certainly isn't the most desirable option. I'd love to hear thoughts on carbonation options, and the risk of prolonged anaerobic fermentation.

Headaches can also be caused by your pH being off. Drinking lots of kombucha could do that.

Hello.
Do you know these sugars used in France and Belgium? If so, can they be used in the production of Kombucha?
- Vergeoise blonde or brunette, or the link in French http://fr.wikipedia.org/wiki/Vergeoise
- Brown sugar, brown sugar kind.

Bonjour.
Connaissez-vous ces sucres utilisés en France et en Belgique? Si oui, peut-on les utiliser dans la fabrication du kombucha ?
- Vergeoise blonde ou brune, voire le lien en français http://fr.wikipedia.org/wiki/Vergeoise

@deathpod : You can get a mother from another kambucha batch. When the tea is brewing , little baby kombuchas are formed and they can be given to anyone, then they will turn into the mothers. There's a full explanation on http://www.brewingkombucha.com plus there are some more photos for you to see of the brewing process.

Check out the clothes that a British designer "grows" from yeast, bacteria & tea .. sounds like scobies to me. I see no reason why it couldn't be flattened when wet, pressed together to dry in sheets & then material cut. They call it BioCouture. The site with the pictures of the jackets is at :

I think MOV would work as well. I've used them interchangeably for bandages & they both turn out like leather when dried. The pics show it looking to me, at least, like native brain-tanned leather. It can be dyed with natural dyes they say.

Yes , Kombucha can be made into a "leather" alternitive , but production methods as of now are still only able to produce a very water soluable version of leather , meaning , as previous comments about the scobys here " Slimy when wet" ...
So not too good if your motercycle jacket would met when you splash in a puddle :) . hope somebody combines it with beeswax or something like that to improve water resistance

To add to "Chard"'s comments about adding sugar to the bottle to increase fizz... Intead of sugar I thought I would compliment the natural apple essense of KT by adding unfiltered bottled apple cider when I bottle.I have been having really good results adding about an inch to a 16 oz glass bottle and leaving about an inch of head-space and then put the bottles back in the "incubator" at 75 F for 4 days or so (no explosions-the re-used plastic lids did expand a bit.) Also, a mix of the cider and a small amount of ginger juice with the bits from pressing through a garlic press (a little goes a long way). I love both these flavors ...sparkling apple cider and the ginger/apple cider. I think the ginger/apple mix is especially good if you have a cold or during colder months. I was nervous about using a non-pasturized juice because of mold/contamination/etc (the bottled cider is pasturized) but I went ahead and made fresh mango juice/puree and added an inch of that to the bottling. All I can say is wow on the fizz! It was a very tasty batch, if very hard to get into the glass! I would have to guess that the alcohol content is higher since the raw juice will ferment, but not real sure. I took samples of the Mango to my local health food store and they swore it tasted just like GT's Mango KT. My next trial is going to be with fresh peach juice/puree because they are on sale this week at Safeway for 49 cents a pound! So, there you have it. My fizzy flavor taste trials ;D Contact me with what you have been trying! Christine Peace and Love!

Good perception with the blendings!

I would try adding some STEVIA leaves to the bottle as a sugar substitute that would increase the fizz.. Stevia leaves are good because, though not as sweet as sugar work well as a natural substitute and helps diabetic persons with their illness.

I noticed that when preparing any sweet fruit juice with water and stevia leaves, after bottling it and keeping it for a week, it starts fermenting and becoming alcoholic. As if stevia would be eating the sugar of the fruit and transforming it into alcohol...

I must try kombucha!

THXs!

I'm not sure you would be able to use stevia. The sweetness from stevia doesn't come from sugar, but from something else.. Unless it's a carbohydrate of the sugar strain it won't ferment. Starches as an example are a carbohydrate but won't ferment without being broken down into sugars ..
While it's a great idea, i don't think stevia would be an adequate fermenter for adding fizz... sweetness yes, fizz no...
Though it can't hurt to try and prove me wrong ;)

The only thing you can do is ferment it for less time. Make your batch for about 5 days. It'll have less alcohol, but also less of the beneficial acids that we want. It really is such a little amount of alcohol, anyway, I say just make it how you like the taste. http://goo.gl/35zcT

I have a question about this. I saw this instructable and was really fascinated by it, but never got around to doing anything. (considering I don't drink...) Anyways, I've been working on a project to brew tea at work (TONS of it) and we bottled a few gallons for reference. well... a week later (this is unsweet tea) I realized they needed to be thrown out. needless to say, at least one has stuff growing in it. most didn't look great, but one... well I looked at it and said "by gosh, is that a mother?" (see picture) Anyways, what do you think. I didn't add anything, the jugs were sanitary, and the tea was brewed at 202 degrees. it SHOULDN'T be mold. Now, (I'm working at a fast food HQ) this is a kitchen, so there could be some yeast in the air. so i thought it may be possible this is actually a mother. They have been working on bread products a lot recently. What do you think? do you think it'll turn into kumbucha? it is a skin, it's new, but it looks like the pictures above. I added sugar to see what happens, this really facinates me, even if I won't drink it (maybe I can find someone who will IF it's safe ) what should I look for to let me know if it's poisonous or if it's the real deal?

Well sure you don't drink, but Kombucha really doesn't have that much alcohol in it at all. It's legally classified as a non-alcoholic beverage because it has less than perhaps 1% alcohol when it isn't fermented for too long. I think there's a little bit of alcohol in some things that we drink everyday and we dont even know. Try drinking it and see if you can even really taste the alcohol, but i mean, i don't even know what it tastes like so ... but this is just what i've heard

 Sorry to keep commenting on an old Instructable but it is a good one and I want to offer a few things. :)
If I were making this I would use a hydrometer (cheap at $8-10) or refractometer (more costly at $60-75) to keep an eye on the fermentation of the sugar. When the specific gravity stabilizes for a period of a few days, you can then add 3 to 5 ounces of dextrose (corn sugar available at all homebrew stores) and bottle in glass. Easy as pie and you don't have to worry about bottle grenades. This is the standard practice for brewing beer at home and bottling.

triplenine sagt: Mär 25, 2010. 3:41 nachm.
 Although, I am taking full attenuation into account. Some people may not like a fully attenuated kombucha and then you may bottle earlier than I would with my mthod to retain some sweetness and lose control over the carbonation. Typed faster than I thought on that first one. ;)

I've been toying with the idea of making things out of dried SCOBYs. Couldn't you grow the SCOBY in a container that was in the shape of the thing you want to make? For example, why not create a "wallet" sized container for the SCOBY.
Or why not a "jacket-shaped" container.

Of course the SCOBY will shrink when it dries, so maybe it's better to just make big sheets. Would a SCOBY grow in a small child's pool so you have a 5' SCOBY?

The "synergy" brand I tried said on the bottle .5 % or less alcohol. I dont know how to determine the strength of my own batches (I've only made one so far) but I'm guessing that it could get pretty high if done right.. My reading has indicated that the yeast makes alcohol and the bacteria eat it to make the various  vinegary acids.  I find they taste like wine coolers to some degree with a cider like  taste.

Today, for the first time, I actually had to toss one of my vats that had grown mold - and that only because I checked it about ten days ago and apparently introduced some little nasties. Otherwise, it is pretty damn fail-safe. Follow the directions Tim gives, don't be fraidy-cats, and enjoy!

Chard
Chard sagt: Sep 29, 2009. 12:14 nachm.
ok i have never made this before (im planning to when i have finished a few other projects) but i know a bit about brewing. the likely reason for the no fizz is that your leaving it in its 1st stage of fermentation for too long and all the sugars are used up. this means that when you put it in bottles theres no sugar to turn into CO2 (and alcohol). its the same with brewing beer. 2 ways to avoid this are to bottle it a few days earlier than usual so theres still some sugar left or you can add more sugar before bottling. this second method is called 'charging' in homebrew speak and all you do is add 1/2 to 1 tsp of sugar per pint or so of liquid into the bottle before you pour in the liquid. then give it a swirl to mix it in and seal up the bottle. hope this helps / works

Because it's not that good for you. The oxalic acid has this nasty little habit of causing kidney stones, and it's really really really hard on your poor old liver. In fact, it's toxic. I love the taste of this stuff (kind of like a sour apple cider) but it's just not beneficial because of the kidney problems, and the amount of sugar you have to use for it to taste remotely good makes it a super high calorie drink. Nuh huh. Not for me anymore. To each their own though.

I've been brewing Kombucha for about 2 years. And stopped drinking it after the first month. Let's be honest. It's not that good for you. It has a look of sugar, and one hell of a lot of acid (oxalic). And I doubt the veracity of its health benefits when you consider what it might do to your kidneys. Right now, my mother (culture) has been brewing undisturbed for exactly 18 months.

You should know that "Kombucha" is not Slavik word(tea beverage popular in Russia...., it came from Japan). Here in Ukraine we use word "kvass" http://en.wikipedia.org/wiki/Kvass

There is actually a disambiguation of the two terms, as Kombucha is the english spelling of both. If taken from slavik and not changed it comes out more like what we read, but the Japanese "kombu-cha" means "tea of kombu" which is not fermented in any way, it's just a form of tea.

Yes, mildly. Depends on how you brew it. The yeast part of the symbiotic collection of bacteria and yeasts is responsible for the alcohol content, and there are ways to manipulate the brewing process such that the yeast activity is either suppressed or emphasized.

even though this is an old comment, I'll reply for anyone that wants to know. Usually when your Kombucha is ready for drinking (by tasting it along the way to your liking). You bottle it in EZ-Cap bottles and to maintain the fizz you put the bottles back in the warm spot you brewed the Kombucha in. I myself made an incubator for mine. I usually leave them there for a day then put them in the fridge. If you leave it too long pressure will build and they can explode.

I brew 2-3 gallons at a time and always have leftover that needs to be bottled. I went to my local brew shop and bought a box of 12 1 liter EZ-cap swing top bottles for about $39. Be careful when filling as it will fizz some so hold the bottle at an angle. Use a fresh drinking straw to suck out the bubbles (don't cough) then keep filling it up. Cap it and leave it out for 12-24 hours to build pressure and keep the fizz, then put them in the fridge. NEVER use honey, it inhibits microbial growth and will harm the scoby. They say only to use plain jane processed sugar. btw, the typical recipe is 1 cup sugar per gallon, any more and it tastes like sweet ketchup to me. I would say don't mess with it by adding other yeasts and what not. I would only think it MIGHT BE ok to add some pro/pre-biotics from pills but who knows... Cut your scoby in half (haha, good luck) and start a different jar for experimenting. Drink at your own risk!

 I use the 500ml german beer bottles for mine, using a bottle capper to seal them when refrigerating. Good for a year or more and still fizzy. I don't use sugar, since I am diabetic, but rather agave nectar in the same measure as sugar. You can leave it at room temperature for a week before refrigerating. That will ensure some fizz. You can't use honey, since it is antibacterial. No need to add yeast, unless you want beer. It would probably kill the mother. You can keep a mather without brewing for a year or so by periodically adding sugar and tea to the jar.

Continuous brewing is too disruptive. You should have 2 or even 3 gallon sun tea jars that you cycle between if you want a constant supply with some extra, you can bottle it up with EZ-cap bottles. Use green tea instead of black tea to get more fizz. Bottle when ready then let them sit sealed up out in the open for a day then put in the fridge. Fresh is always more fizzy. Cold isn't as much. 1 liter EZ-Cap bottles are perfect! Make yourself an insulated box with ventilation to make a incubating temp of 85 degress for fast growing. Ready in about 12 days! ...or set it on top of the water heater.

Yup, it worked. Not too badly, actually (considering I had transfered all of the nasty lactic acid producing bacteria over to my first batch). I made a small batch in one of those POM tea jars, now I'm on to a huge gallon-sized jar. Nice. Oddly enough, the tendrils I was so excited about either shrunk, fell, or died off. There were only a few of them left when I decanted/harvested/whatever. This might have been because I was curious, so I kept rotating and inspecting the jar daily, and also tried putting it in the fridge for an hour or so (as Tim says cold seems to favor the tendrils).... I'm leaving this batch untouched, in the dark, in a cabinet to see what happens. Hopefully the results will be better than last time (there was a little flavor development, but mostly it tasted slightly better than a dilute apple cider vinegar.

Well the mother appears to be growing.

This is silly. You absolutely must use glass because as harveyparadox says: plastic IS toxic. The acidity from the kombucha will actually eat through layers of the plastic and toxic chemicals will leach out into the kombucha. Metal is also a no-no. To solve the problem of exploding containers - it's simple! After bottling, (fill to the brim) just refrigerate the brew. This greatly slows/stops the fermentation process. I have been brewing/bottling kombucha for months and never once had a container "explode." Also, you don't have to bottle it just before it's ready. Wait until it tastes just right, and the refrigeration will keep it at that point.

The sugar is eaten up by the whole fermenting process. The longer you let it brew the less sugar is left. It gets really acidic though! Gotta figure out that right time by tasting it every day, usually takes 12 days at 84 degrees. Keep your sugar measurements consistent. One time I added about a 1/4 cup more sugar per gallon and it tasted kinda like ketchup. I didn't like that.

any fermented product needs to be refrigerated once it is sealed air-tight unless you are absolutely sure that there is no more sugar for the culture to "eat". two weeks is a long time for the pressure in a bottle to build up if the kombucha is still fermenting...if you aren't familiar with the term "specific gravity" then you are best off playing it safe and putting your kombucha in the fridge after a week or so in the bottle... i would stick to glass though...plastic is toxic! good luck!

What? Did you seal the damn things?? They need air to breath.. and if you fill them too high the scoby will plug the top shoulder of the jar.

I would hazard a guess that just because it was traditionally done in Russia, doesn't mean that it is safe or smart. Traditionally Russians eat raw bacon, and use communal jam spoons that they all lick off after they're finished (I grew up with several Russian immigrant families and exchange students in Alaska). I mean Native American's can drink water from streams and not get sick, the rest of us however, probably shouldn't do that. I would suggest that if one wanted to try this that they use proper beer brewing sanitation techniques, use a proper beer yeast & wine additives (lactic acid, etc). The final output of this product is very similar to a Lambic. Lambic's are traditionally wild fermented, but ONLY in one specific region in the world where the proper yeasts are airborn. But if you bought a Lambic kit, you cold probably replicate this beverage and not end up with a massive headache and gurgling gut disease. Lastly, it would be smart to replace all of the sugar with corn sugar, or dry malt extract. In the US, brewing with white table sugar is a BIG No-No. In Europe & Northern Asia they don't use the same kind of table sugar as here in the US, so just because they do it there, doesn't mean that we can do it here.

2 places to get Kombucha starters for free (pay for postage):

and the Kombucha Exchange

http://www.kombu.de/suche2.htm

The first site is a Kombucha group of enthusiasts that can answer any questions you might have. They also have some brilliant resources like how to make a facial cream out of kombucha culture (really!).

BTW, if you're reasonably hygienic and follow the instructions, particularly to ensure proper acidity, Kombucha is perfectly safe. It's been brewed for centuries in Europe and apparently, there's never been a fatality associated with the consumption of Kombucha.

Enjoy it, it's rare these days to be able to create a food that tastes great and makes you feel even better!

Kombucha is as "easily contaminated" as a grilled cheese sandwich is "easily made carcinogenic" (i.e. charred and burnt). There are simple causal relationships involved -- it's not microbial roulette. It takes some know-how to avoid burning your food on the stove; likewise it takes knowledge and skill to understand the kombucha brewing process such that it produces a proper healthy culture and product. That said, it's really pretty easy to get a proper healthy culture going. The first 4 days with a new culture is where it's most vulnerable to contamination, but once it starts getting nice and acidic, the culture and even the medium itself are extremely resistant to infections. (That's sort of where the grilled cheese analogy falls apart, I'm afraid.)

Actually, even from the start, there is TOO MUCH SUGAR for the K-brew to be easily contaminated! The vast majority of bacterias don't like to be overwhelmed with sugar. That's why SCOBY/starter is usually necessary, because it takes bacteria and yeast working symbiotically to start. Sometimes you can use vinegar (old-fashioned or homebrew, not white or balsamic) to start, but vinegar uses a similar SCOBY called Mother of Vinegar

Hey, I was curious if the mother used to make this stuff is the same as the mother used to make vinegar. It looks similar except for a few things. From what I understand the mother in vinegar feeds off of alcohol and is what makes vinegar what it is instead of wine. It sits at the bottom until it has absorbed all of the alcohol and then rises to the top when there is nothing left. And you can propogate it just by cutting off a chunk and throwing it into a new batch. Since you say that it is fermented I was wondering if it has alcohol in it which would suggest that this mother is different. Any clues?
StuartG
StuartG sagt: Feb 19, 2007. 8:46 vorm.
In this recipe the mother is natural yeast, the yeast acts as an enzyme on sugar and ferments it to produce alcohol and carbon dioxide. The mother for vinegar is bacteria which will ferment alcohol (oxidizes it) to produce vinegar - acetic acid. This is the fast way to make vinegar, slow way is to expose it to air over a long period. There are a couple of posts on safety; starting with boiled water result in a cleaner starting point; alcohol (and vinegar for that matter) limit growth of many bugs. Pre modern water treatment this made drinks like this safer than most public water of the time. If your really concerned about safety, replace the mother with a wine yeast. Use a five gallon wine fermenter with an airlock. The brew you'll get will be stronger (wine yeast tolerates more alcohol than the natural yeasts in the mother). Wait until fermentation is finished (no co2 bubbles) after sediment settles siphon into clean container. The recipe my Gran used was similar to above plus 4 lemons and a pound of raisons. She called it wine - it was an OK drink but stronger than many commercial table wines. The higher alcohol content and sealed fermentation produce a more bacteria free product. Few bacteria do well in 20 proof liquid. The yeast is also ultimately killed by the alcohol it has produced (note: too much of a good thing). Mother cultures are also used in sour dough, ginger beer and don't forget the bacteria in cheese / other milk products. Hard cider uses natural yeasts in the apples this can produce both ethanol (good) and methanol (killer in large quanities over time - this is where the expression "blind drunk" comes from). Bacteria and yeasts are friend and foe. Humans have been making use of them since the stoneage - there are risks but commercial products have there issues too, even peanut butter .... If you decide to experiment respect your sense of smell, taste and start small .... Sorry Darkman - kinda replied to point on vinegar and safety in one plus a bit long winded.

In fact *insert history lesson here*, beer and ale were the most commonly available beverages in the middle ages, mostly because they were actually safer to drink than the disgusting water from streams and rivers, which was contaminated with pretty much everything you can think of. Before hops and the advent of longer-lived beer, ale was the beverage of choice. Each village had a woman who took care of brewing large vats of ale for the town, placing dried branches above her door to indicate that ale was available. After beer came along, the process began to move out of homes and into larger brewing centers because the drink stayed drinkable long enough to transport over significant distances.

Would they allow someone to even post that? I'd think they would be nervous someone would poison themself. But it might be useful to do extractions from medicinal plants, that would be useful and fairly safe.

Isn't Roquefort cheese a symbiosis with penicillin fungus?

Any bleu cheese is a form of penicillin.

If sanitary measures are followed, brewing your own alcohol is safe, no matter what 'loopy-new age' ingredients you make it out of. And I agree with Tim, I'd love to read an instructable you wrote (about anything). I'm leaning towards penicillin. If you used refridgeration it might even be "peni-chilling." ;)

This isn't about brewing alcohol, though, it's about culturing something your sister's friend's yoga instructor gave her. Yeah, my sister did the kombucha thing. Has someone done a still yet? I've got the parts waiting for me to get around to it.

"Kombucha is a fermented tea." Fermentation means yeast. Yeast make alcohol (and c02, and more yeast). This recipe is about making alcohol. It's about culturing yeast ;)

Alcohol content, a product of yeast fermentation, ranges from .5-1.5%.

There is yeast and assorted random other beasties in it. Quite possibly some that are harmful, according to the JAMA article I pointed to.

dude... fermentation is not only by yeast (it can be of a bacterial or of a non-yeast fungal nature), nor is it only related to alcohol. There are acidic fermentations too. Think pickles, sauerkraut, kimchee, soy sauce... for some examples... :)

Dont eat yogurt either it too is formed by rampant bacteria you cant control... you wouldnt want a spoon full of anthrax.. would you? Also only granola crunching hippies and yoga instructors eat this sort of thing. The only reason you would culture this is to buy into that leftist fad (it came from commie russia!!), not for any health benefits which I know dont exist since I havnt looked for them.

my experience with drinking kombucha has been beneficial. It tastes so much like apple cider vinegar i'd image the health benefits are similar. also the probiotics brew vitamins. it came from china more than 2000 years ago. theres even a passage in the bible referring to a drink people think was a similar fermented kombucha like vinegar beverage. hardly a fad.

We don't tend to have anthrax in this country. It is frequently found in articles made with goat hides or goat hair, and from just such countries as Iran. Even then, I suspect that if you were to wash your hands frequently and can keep yourself from being tempted to use an old goat skin as a bottle cover, you would probably be safe, at least from that particular contaminant. :-)

Yes. Anthrax. I'm sure that's what'll happen. Except that anthrax is an anaerobic bacteria in which the spores commonly come from dirt. The main part of Kombucha culturing is aerobic. By the time you create an anearobic environment (when you bottle it) the liquid is teeming with bacteria. GOOD bacteria! These will outcompete the Anthrax. Honestly I don't know where people get this shit from. You're more likely to get anthrax from scraping yourself up outside.

I have been interested in making this stuff but I've got lots of questions I take it sanitation is not even a issue here? IE guy says everthing is sterile than dunks his hand in the wash, takes a sip & pours the rest back. Would sanitary practices such as in homebrewing be advised against or would this make for a cleaner pure finished product? or is this more of a lambic type brew which is dependent on open fermentation. Could I use a glass carboy with air supply via aquarium pump & if so should I use an in line hepa filter? Also could I keep culture of the mother on slants or plates? & last how much fermentation is involved anybody know the ABV if any, I have a feeling the fermentation is not complete & using glass bottles would be advised against Well I'm off to do some research This looks like a promising new venture Thanks for the instructable

Kombucha is delicious! The culture that grows in the brew is called a "SCOBY" a "symbiotic culture of bacteria and yeast" Talk to folks on freecycle, or put up a nice note at a health food store, you're likely to find someone to give a starter to you.

cool i live in Pittsburgh and might be able to find the "mother" in any Russian food store. Couldn't you just heat it to kill of the culture and stabilize the mix?

The mother is actually a combination of Acetobacter xylinum bacteria and various yeasts in a cellulose matrix. The cellulose is created by the Acetobacter and is known as microbial cellulose. This microbial cellulose has been used to make paper for high end speakers. US Patent 4,742,164 shows a patent for the use of microbial cellulose in these speakers. Anyone want to do an Instructable on how to form the mother, dry it, wash it and make it into a speaker?

Hrmm... my post got lost or I forgot to post it :P

I've never even heard of this (I missed the other project too :P). As soon as I can acquire a mother, I'm gonna start making this :)

A few questions.
Is there a time limit on secondary fermentation? That is, will the drink go sour/foul or will the bottles blow their tops from excessive pressure?

Second, can dormant yeast from secondary fermentation be re-used during primary fermentation. You know, to tailor a strain of yeast just for making Kombucha :)


Oh, and anyone in central Florida with some mother to spare :)

Ha! This scared the shit out of me when I saw it at Tim's MIT hangout. It reminded me of a 1950s SF film. Was I going to be "absorbed"??? I tasted it as a test of manliness, but yes indeed, it was surprisingly good, nor am I Russian or New Age freak (I don't think...) ;-)

I love this tea. I used to make it a few years ago, but I moved and I lost the starter. The first bit was a gift from a friend in Toronto( Now deceased) and I do not know where he got it. Do you know where I can get a starter "Pancake"? Thanks.

You can get a good quality starter here, and whatever else you need for tea.
I used to make kombucha, and miss it.
