Making Kombucha

Kombucha seems to be the new "it" drink (although I live in the Bay Area, so this info may be biased). Of doubtful origin, this fermented tea has a passionate following who claim all manner of health benefits for it. I just like it because it tastes good.

Step 1: Obtain Kombucha starter

You can buy the yeasty starter on the web (sometimes misidentified as a mushroom), or get it from a friend. You might also try looking on message boards of health food stores.

The starter replicates itself in each batch, so one is enough for your lifetime. Soon you'll have enough for everyone you know!

 Instuctable: any advice on brewing time or taste or small etc to get the least amt of alcohol possible? not sure if shorter time has less chance of alcohol to develop or longer time frame gives more chance it's eaten-up and turns to vinegar??? thanks!

don't worry there is more alcohol in your mouth wash 
rubytuesday2 in reply to abadfartMar 23, 2010. 10:07 PM
 um no. i use Tom's of Maine alcohol free.

I remember reading somewhere that kombucha usually contains about 0.5% alcohol, so getting drunk from it really isnt an option if thats what you want to avoid, infact your cells would probably burst before you could even feel an effect from the alcohol

Another Bay Area friend! More people live here than I think, I guess :)
I personally hate kombucha, but my best friend LOVES it (ever since she got a boyfriend who also loves it), so I'll be making this for her birthday!

Ok it may be a stupid question but I have to ask. Do you just drink as is after the 7-14 day cycle? Can I add natural juices to it? Can I bottle it?
CapraRoyale says: Dec 13, 2010. 1:41 AM
Metal only threatens the well-being of the active cultures.
Brewing tea in a metal pot is fine because there are no cultures during that stage.
reverendbubba1 says: Jun 7, 2010. 4:26 PM
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 because of the acidic nature, which kills the starter.
CapraRoyale in reply to reverendbubba1Dec 13, 2010. 1:38 AM
From what I understand, it's not in fact the acidity, because the bacteria thrive in an acidic environment.
That's why you add some of your previous batch into your new batch to bring up the acidity.
It's the Bergamot oil which floats to the surface (as oil does) and cuts off oxygen for the yeast and bacteria.

when do you put the olive oil in?

What does the starter make the tea taste like? This sounds good, but I'm not a big tea person, I do like some kinds though.
harley_rly says: Jun 6, 2010. 10:02 PM
could this be done with just yeast
maven in reply to harley_rlyJul 12, 2010. 5:21 PM
No, the Kombucha Scoby (Symbiotic Colony Of Bacteria and Yeast) is a melange of several strains of bacteria and yeasts. It is closer to a Mother Of Vinegar than a straight-up yeasted beverage. With yeast, you'd get tea wine.
harley_rly in reply to mavenSep 3, 2010. 9:05 AM
oh, ok then. i went ahead and did it with yeast already. it may not have been Kombucha, but it didnt taste half bad lol
new2raw says: Feb 27, 2009. 6:11 PM
Hey,
I have been trying to get a batch ok kombucha started for about a week and a half now, and I'm not sure if its working =/ I used a bottle of the store-bought stuff to get started, because I have no other "kombucha friendly" friends or family. I was wondering which "Bay area" you are in. I'm sorry if you have already posted this, but I didn't see it. Anyways, thank you all for any help.

maven in reply to new2rawJul 12, 2010. 5:17 PM
I started my own Kombucha from a bottle of unfiltered GT's green tea kombucha from the store. I had to let it "work" for a month (December to mid-January) before the scoby (mushroom thingy) grew to a substantial pancake. I added 2 cups of liquid kombucha, especially the sediment in the bottom of the bottle, as the starter to the sweetened, cooled black tea. The tea needs to be acid from the fermented kombucha to fight off molds and stuff. It can be done, but it takes patience to let the stuff grow enough.
Rakala in reply to new2rawJun 11, 2010. 10:42 AM
New2raw, I see you posted this awhile back, so I hope you had success one way or another. If not, and you'd like to try again, there are a few things to keep in mind: 1. Temperature makes a big difference; the warmer the better. 2. You might have just had an not-great starting batch. Make sure you start with bottled kombucha that doesn't have any additives- fruit juice or pulp or anything. To start, you need the plain stuff. If any avaliable brand is brewed nearby, that might be your best bet, since it is less likely to have had a chance to die at some point in the supply chain. You could also try The world wide Kombucha Exchange (http://www.kombu.de/english.htm) to see if you can't find someone in your area to send you a culture. 3. When starting in this manner, it does take awhile to see a thick mother form. You'll start to see a cloudy skin on top. I started brewing mine about 12 days after I first started the whole process, and it's been very hot here (I don't have A/C). It wouldn't be unreasonable to take 3-4 weeks if it was very cool, I wouldn't think. Best of luck!
reverendbubba1 says: Jun 7, 2010. 4:38 PM
The longer it sits,the better the Kombucha.
reverendbubba1 says: Jun 7, 2010. 4:35 PM
Try not to touch the starter any more than you have to...as the oils in your skins can deaden the starter,too.
reverendbubba1 says: Jun 7, 2010. 4:33 PM
You should only use non reactive spoons & pitchers for the tea, as it could kill the starter.
reverendbubba1 says: Jun 7, 2010. 4:30 PM
You can use many things to flavor the FINISHED product,but always wait till the Kombucha is finished. Sweeteners that have been used to sweeten finished product: Sweeteners that have been reported to work: Agave nectar or any nectar you like Pineapple Juice Honey Brown Sugar White Sugar
Instuctable says: May 29, 2008. 3:17 AM
It would be a sin to keep it to myself, I just joined the site just to share this: you don't need to "get" the starter Kombucha "mother" -- you can make one in a couple of weeks yourself.
There aren't many things, so healthy, that are this simple. The yeast grows on the nutrients dissolved in the culture of boiled tea leaves plus sugar, right?
Make some tea or even use the remainder of some tea leftovers. Basically, to make a mother, a very small one at first, brew 1 tea bag in 1 cup of water and add 3 tsp of unrefined sugar in a clean jar covered with cheese cloth kept in place with a rubber band or a string tied around the top/lip. Let it sit in a dark place, allowed to "breathe" until a strange-at-first foam appears on top, in a few days it solidifies. That's the baby Kombucha mother, more or less yellow-beige and slimy. It will have a distinct sour, vinegary smell, and if you smelled it before you will be able to recognize it. Taste a tea spoon of it to make sure it’s Kombucha and/or wash the tea spoon and ask another connoisseur.
Just to pass on a warning, I understand some people achieved growing something else in such a culture – cool! I have not seen anything but a Kombucha culture come out of the following recipe. If it looks or smells more like mold than vinegar I would seek advice. For me, that had never been a problem. If it somehow got contaminated, be brave and throw the whole thing away. Start all over and keep it clean.
To make a few glasses of Kombucha, just to give you approximate proportions (and do experiment to find your own favorite) for a gallon jar (my favs are sun-tea jars with a tap) brew 4-7 teabags or tsps of black tea in a separate wide-mouth bottle, jar or a coffee pot, along with a cup of any, hopefully not very processed, sugar. Let it cool off to room temp, then gently pour all of the above into the jar along with the Kombucha mother and the liquid it’s in. For a sure new “start” never transport the mother alone without it’s liquid. Cover the jar with a cheese cloth or whatever will let Kombucha breathe and keep bacteria, mold and tiny fruit flies away. Let it sit for 1 to 3 weeks, taste it by pouring out a sip at a time, do not drink form the Kombucha jar – keep it as sterile as reasonable.

Once you make your first batch, you may well wish to experiment. Here are some of the main variables:
1. The size of Kombucha mother mushroom. Of course the bigger it is the faster it will eat up the sugar, ferment, convert it into the elixir we know. But if it gets too thick, more than 2” or so (and in the right conditions it grows quite fast) it may not be able to “breathe,” so it’s lowest part will look not too appetizing, which means it’s time to either give a horizontal slice of it to a friend or start another jar!
You can make it a batch at a time or pour yourself a cup or more every day if you add as much brewed tea and sugar back. In case of batch making, you will get a new layer of mother with every batch, then you can discard the lower portion or let it “seed” a new Kombucha mother. The lower, older mother may look like it died making a new one. Actually, it being a conglomeration of billions microorganisms -- they just traveled upwards, towards the air.
The horizontal size of the mother will be only as big as the surface air it can reach.
2. Second biggest variable is the amount of sugar, simply put, the more sugar the “stronger” is faster your Kombucha will develop. Experiment.
3. Time it is allowed to ferment determines it’s acidity, effervescence, alcohol content (usually .5% to 1.5%) and taste. When you like the taste, remove (possibly, not necessarily, using a sieve) all but a couple of cups from the Kombucha jar (now it’s ready to start another batch) and pour them into smaller bottles with good lids (no metal touching nowhere.) Let them sit at room temp for a couple of days, to increase effervescence and sharpen taste, or refrigerate them right away. Again, experiment, it is hard to go wrong, some of your “bad” batches may taste better than some commercial ones!
4. Try different teas and additional flavors, like ginger, mint, lemon, et cet, added before or after brewing. To be honest, I have not ventured that far to be an expert of what is best before or after.
5. Your ingredients and patience (or forgetfulness) will determine the final taste.
6. Last but not least is the temperature during brewing/fermentation. Warmer, but not too warm (70-85F) is best, whereas slightly below room temp is not a problem, but will certainly take longer to ferment.

Fermentation depends on these variables in a very simple way, higher temp –or- more sugar –or- more time = more fermentation. Too much or too little of either may prevent proper fermentation. In hot climate, it may be advisable to brew it slower, like in a cool/cold basement or the lower part of the fridge.

Important:
1. Do not use anything that may have or had preservatives – it will harm Kombucha, possibly producing a dubiously-healthy mold.
2. Keep everything clean, very preferably all glass. Kombucha is both sweet and acidic – it will dissolve some plastic and may imbed or damage wooden or rubber surfaces.
Try not to touch the culture or the brew to decrease the risk of contamination. When you transport it, and simply pouring it out is not possible, handle it’s slimy layers only with freshly soap-washed hands. Enjoy the feeling!
3. Use boiled water to evaporate the chlorine in tap water. Bottled or clean well water should be fine.
4. The Kombucha mother is a friendly yeast colony, a live culture – treat it lovingly, really.
5. Use everything organic. Did somebody actually ask why?

Enjoy, may you be healthy!

You should really make an Instructable about it, your tips are very useful! I think if you make an 'ible about it more people will see your tips. And Btw, does it have a strong smell this way? Because I'm planning to brew my Kombucha in my lockera at school, since I never open it.
nthmost in reply to InstuctableJun 23, 2008. 3:47 AM
Just to boil this post down for people (pun intended), the gist is:

You can make more kombucha by using a commercial bottle of kombucha. There is enough viable culture swimming in that liquid. Get as many of the "floaties" you can into your brewing jar and just start feeding it.

My own caveats about this -- potential downsides of this method:

  • Low success rate for novices to the brewing process
  • Much higher chances for contamination since the culture is very weak
  • Takes a long time (up to 30 days) to generate a strong mother
So...

Whenever possible, and especially if you are a newbie to the world of kombucha, acquire a strong mother rather than trying to generate one from a commercial liquid.

And if you still want to try doing kombucha this way, see if you can make friends with someone who's been into it for a while -- you'll benefit from their experience and intuition, because they'll be able to tell you whether the brewing process is going well.
shalow in reply to nthmostNov 5, 2011. 6:41 PM
I believe you may have miss read the top part, he says you can make a mother without any kombucha.

Also while he says it only takes 5 days from the foam to form, til you have a small mother, he doesnt say how long time it takes for it to form the foam, but i doubt it would take 3 weeks for the foam to form.

At any rate this is an interesting experiment and I now have 3 cups of tea hidden away in a cupboard, heh
IvanJM says: Oct 14, 2007. 12:04 AM
A couple of things. First, it contains both yeast and bacteria. The type of yeast is similar to beer yeast. The bacteria is similar as is used to make vinegar. The yeast breaks the sugar into simpler sugars, CO2, and alcohol. The bacteria convert the sugars (glucose) and alcohol into weak acids. Drinking early will have stronger yeast populations so will have more fizz and a sweater taste. Just don't wait too long, most don't like it too acidic. At no stage is alcohol normally near 1%. Second, brewing your tea in a metal container is fine. It's just not a good idea to use metal with the finished product. Because the finished product contains acids it will react with most metals. Many of the compounds created in this way are toxic. Though it would be extremely rare for these toxins to have noticeable affects until levels had built up over time. Arwen, I'm curious to know how you would describe the differences in flavour between hot and room temp. steeping. And have you tried syrups? I know most places will say it's best to use white sugar only, but I believe this is based on a paranoia that the yeasts and bacterias will be disrupted, lost, or what have you. Syrups are easy to make and probably safer than a second ferment with raw or dried fruit because they are heated.
ofmay in reply to IvanJMDec 19, 2009. 7:45 PM

I do not use white sugar if I have to I use unrefined. But my preference is to used Maple Syrup or Guava or honey.  I use a 2 gallon crock and brew the tea in the crock pouring the sweetener in first followed by the hot water slurring briskly from the bottom and finely tea bags. The 10 bags go in for 10-15 minutes. Set the crock on a cooling rack. The next day add the mother when cooled with some extra butcha juice.  2-3- weeks not to tart not to sweet!

SisterMable in reply to BlondGuy101Sep 11, 2009. 6:33 PM
Earl Grey is strongly flavoured with Bergamot. You should avoid any flavoured teas, as the oils from the flavorings can distort, and sometimes even kill, the mother. The volatile nature of the flavourings can also produce off flavour in the tea itself.
Doctor What says: Oct 12, 2007. 2:19 PM
Fermented, Yeast... Sounds alcoholic. Is it? If so, can i make a virgin type? I'm not a fan of alcohol, and i'm 16.
maven in reply to Doctor WhatNov 11, 2009. 5:40 AM
the alcohol is converted by the mother to vinegar. That's basically what the Kombucha mother is - a mother of vinegar with some extra bacteria thrown in.  If there's any alcohol left, it's only trace amounts.  Kombucha tastes (to me) like fizzy apple cider vinegar.
arwen (author) in reply to Doctor WhatOct 12, 2007. 2:24 PM
As far as I know, it's *slightly* alcoholic, but not enough to get drunk on by any means. It's sold in grocery stores in San Francisco in the refrigerated juice case and there's no mention of any alcohol content, so it must be too negligible to mention.
Doctor What in reply to arwenOct 15, 2007. 2:22 PM
Yay, now i can actually try the stuff. The only reason that i had a concern is that my dad used to make alcohol, and the process sounded all too familiar. but at least now i don't have to worry about my kidneys.

Rick500 in reply to kengMar 5, 2008. 5:44 PM
Only have to worry about going blind if you drink wood alcohol, not alcohol produced by yeast.
georgedotcom in reply to Rick500Mar 13, 2008. 11:29 AM
Yeast produce both wood alcohol and grain alcohol at the same time. That is why poorly made moonshine causes blindness.

Most commercial distilled spirits are full of alcohols and other compounds you don't want. It is those compounds that cause headaches and other hangover symptoms. don't fool yourself into thinking you aren't drinking wood alcohol too...

The better spirits must be distilled a large number of times to get the bad alcohol seperated from the good. Very little that you can buy in the liquior store has been properly purified. There is one brand of vodka that is almost free of wood alcohol and other contaminates... It's made in texas, and they have a great website that talks about this contamination issue.

King of the wasteland in reply to georgedotcomMar 23, 2010. 2:11 PM
Thats simply an ignorant statement. The alcohol that causes hangovers are called fusel alcohols. many of which are toxic. Most are produced late in a distilation run. NOT in a simple fermentation of food grade ingredients. people went blind from additives such as methanol used to stretch the booze further. Note i said ADDED. Methanol is produced in small quantities by fermentation but negligible. for more real info on alcohol production and it's many myth read ""The Compleat Distiller" Happy brewing.

And here I thought it was the lead solder in the car radiators they used for condensers that caused the trouble!  Well, that and the methanol and lye added for "flavor".
cmistark in reply to georgedotcomJul 22, 2008. 11:37 AM
If you want to do it on the cheap, just run your cheap vodka through a carbon filter (ie Brita) a few times (four is what I've heard is best)
porcupinemamma in reply to cmistarkNov 11, 2009. 5:59 AM
You've got me thinking about the Britta idea-I very rarely drink alchohol, so that's not a project that would be too high on my list of "wanna try", but any other fun ideas that a Britta could be used for?
cfuse in reply to porcupinemammaDec 10, 2009. 5:20 PM
I've heard (but not tried myself) that the brita + cheap vodka trick works on a lot of liquids - including orange juice. Basically, if your drink is both cheap and evil tasting, then it may be worth running it through a couple of times to see what happens.

Yes, so if you don't distill at all, but only ferment (as in brewing beer, etc.), there is no chance of producing methanol.
Rick500 in reply to georgedotcomMar 13, 2008. 12:47 PM
My understanding is that wood alcohol (methanol) is not the result of fermentation, but of only distillation.

danmanders says: Feb 22, 2006. 4:51 PM
you don't need to buy a starter, or even get one from a friend. if your food coop has kombucha for sale(unpasteurized...look for pieces of culture at the bottom), you can just buy a bottle and dump the whole thing in to start it. i used a 16oz bottle of synergy kombucha ,and it worked just fine. now i've got a big one...

Rakala in reply to sonomaJun 11, 2010. 10:30 AM
Sonoma- I have started Kombucha in the past, but I tried it from the bottled stuff this last time, and it worked marvelously. You actually don't add anything to it. Just dump the whole thing in a clean (scrupulously clean) glass jar and let it sit until you start to see a mother form. Make sure to keep it covered, but loosely so. Once the mother forms, treat it as you would any other- use the mother and the liquid to start your first batch.
niceday8888 in reply to danmandersJul 2, 2008. 5:53 PM
I just want to thank you that it really worked. I got a bottle of Kombucha from "Whole Food" and used a 3 cups glasses container to brew my 1st batch, it took 14 days. I only used 10oz out of the 16 oz, I want to see how it taste. Now my 2nd one took 10 days and my 3rd one took 7 days. I guess it is getting warmer and the mother is stronger and bigger now. Thanks again.

Folks: I am surprised no one has mentioned chloramine in this forum, but you might want to do a little research on your local water supply to see if it's a factor before trying to brew using tapwater. Details below. I just took a fermentation class which included info on brewing kombucha. The instructor told us that since most water systems in the US add Chloramine to their systems (somehow it's a more stable combination of chlorine and amonium - but I'm not a chemist and really don't understand), and this cannot be removed from tap water by boiling or just letting the water stand. So she recommended using a few drops of a pet supply product such as Amquel to remove the chloramine before using it to brew. I don't know how it's going to turn out, but I will let you know. She has been doing this for years, and a cursory review of wikipedia entries seemed to confirm what she told us. I am trying my first batch tonight, using a SCOBY baby from my teacher and some locally brewed kombucha from the health food store which I have tasted many times and loved. Wish me luck.

hello, thanks for your explanations. i am preparing kombucha tea in a different recipe. first of all i put 4-5 lt water to a pan to boil it. when it starts to boil i add 12-14 spoon of sugar and keep it boiling for a few minutes. than it doesnt need any more boiling, add 7-8 tea bag and wait for 15 minutes. and take the the bags from pan and keep the blend until it is cool. now it is ready to add kombucha starter and some kombucha tea remaining from earlier preperation. and a little bit vinegar will be beter to keep the starters fresh.

I have a question. I just started my very first batch of Kombucha yesterday. I got a scoby from someone on craig's list. Then I followed all the directions. What's kind of weird is that the scoby is hanging vertically in the jar. It hasn't been 24 hours yet, but is this ok?
arwen (author) in reply to nlbknitterJul 10, 2008. 9:53 AM
Again, I'm no expert, but I think that's fine...I've had some that floated on top, some that settle on the bottom, so I don't see why that would be a problem to have it floating in between :-) The main thing to look out for is mold, and otherwise, just taste it cautiously..it should be delicious! Leave it in longer for a stronger, fizzier, more sour taste, and take it out sooner for a lighter, sweeter taste.

has anyone signed up for the 7 day mini course at GetKombucha.com? I want to start brewing this stuff but want to make sure I don't mess it up first...

thanks

amy
nlbknitter in reply to amy2730Jul 1, 2008. 3:53 PM
I did. It's not that instructive. I have seen plenty of other sites that achieve the same results. At the end you get a sales pitch on his equipment. It's still kind of low-key.
amy2730 in reply to amy2730Jun 30, 2008. 1:14 PM
what's that?
amy2730 in reply to amy2730Jun 30, 2008. 1:16 PM
oops, sorry here's the direct link... Kombucha Mini Course

I just signed up and the first day was all about the history of the scoby... pretty cool info, but I can't wait for the free videos!!

I'm on my 6th batch of Kombucha, and love this stuff. The health food stores sell it for about $4.00 a bottle, so I have bottled mine up and have several weeks supply. I didn't like the green tea, it seemed to lack flavor so i switched to black tea. It's much better in my opinion. I drink a couple bottles of my own brew everyday for lunch instead of going to McDonalds and have lost about 15 lbs. For my last batch I substituted Orange Blossom honey for the sugar and it is by far the best tasting batch so far. I had to throw out my old mothers since none of my friends were willing to try it. Here are a few pics of my brew:

harleyxx says: Apr 21, 2008. 6:28 AM
Finally got some Kombucha mother form getkombucha.com and started two batches on Fri 4-18-08. For one batch I used green tea, for the other I used regular Black tea.
harleyxx says: Apr 7, 2008. 8:39 AM
I'm in the Daytona Beach area. Anyone close by willing to donate some mother for my first batch?
discontinuuity says: Mar 29, 2008. 1:47 PM
So I have most of the materials ready to make my own kombucha, but I have a couple questions. First, is it possible to use beer bottles to bottle this stuff? I drink more beer than I do anything that comes in PET bottles. How long would I let it pressurize before putting it into the fridge? Second, can I use other sweeteners such as honey? Third, what would happen if I add baker's or brewer's yeast to the kombucha culture? Would one kill off the other? Would it make more alcohol?
Aerospaced says: Mar 7, 2008. 5:12 PM
If it hadn't been for your reference to Sebastopol, I wouldn't have known wich "bay area" you were in. As for the hotch, I see you havent pasturized the wort. Hmmm, I'll pass on that one. BTW my bay is Tampa. Used to be Monterey.
metaldefektor says: Mar 7, 2008. 4:50 PM
About making the culture? It's so lovely that so many people are so happpy about this amazing drink but I really want to make my own culture, there are lots of exelent comments about making the Kombucha from the culture and to much to read but I didnt browse anything about making culture itself- SWEET!

stasterisk in reply to dillweedMar 6, 2008. 2:00 AM
MITERS has a mother. I have a mother. Lots of people have mothers! Pop into MITERS on Friday, and I'll peel you off a slice of the culture!

comin. i always wanted a piece of yer mom.
amblinman says: Mar 27, 2007. 7:04 PM
I just wanted to make it clear that the tea should be cooled to room temp before dropping in the culture. Don't cook your SCOBY!
surfreak in reply to amblinmanMar 3, 2008. 5:08 PM
He made sun tea, so it's already at room temp. But yes, if you boil (or heat) your water for tea, make sure to cool it first.
nuentoter says: Oct 8, 2007. 12:19 PM
also, if you add lactose, it is an unfermentable sugar that will not be broken down so it will leave a sweetness in your brew even after aging, i use it in all my homebrew beer it's fantastic stuff. northernbrewer.com has tons of stuff, additives and equipment for all this.
sehrgut in reply to nuentoterJan 28, 2008. 10:29 AM
That depends. Kombucha is a much more complex culture than any form of brewers' yeast (which is essentially a monoculture). The bacteria present in most kombucha colonies have some lactose-fermenting abilities, and the acid formed by Acetobacter action encourages acid hydrolysis of disaccharides to more readily-fermented sugars. I'd have to experiment to see if lactose really survived the bacteriofungal kombucha fermentation.
shooby says: Nov 20, 2007. 2:36 PM
So the starter is a solid block made by the suspended ingredients settling on the bottom during fermentation, right?
sehrgut in reply to shoobyJan 28, 2008. 9:42 AM
Actually, the starter is a solid block made by the suspended bacteria and yeast floating to the top and getting caught in a mat of jelly secreted by one of the bacteria. The technical term is a "zoogleal mat" (which rougly translates to "a layer of glued-together animals").
giacomodolce says: Jan 25, 2007. 10:31 AM
Has anyone tried making it in a glass carboy? Like the kind homebrewers use for making beer?
Patrik in reply to giacomodolceJan 26, 2008. 2:38 PM
You can probably *make* it in a carboy. However, the typical carboy has a relatively narrow neck, so you'll have trouble getting the new "mother" out for the next batch.
Patrik in reply to PatrikJan 26, 2008. 2:47 PM
Also, I believe kombucha needs oxygen to ferment - that's why you typically use a wide jar, and cover it with a towel instead of a lid.
Patrik in reply to PatrikJan 26, 2008. 3:01 PM
Ah, I thought I had seen it somewhere... Here's what Tom Anderson had to say on carboys in his Kombucha instructable:

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.

He was talking about plastic watercooler carboys though - I wouldn't recommend trying to cut the top off a glass carboy! ;-)

warning on kombucha. watch out for black or green mould on the top of the"yeast blob"dont drink your brew if you see this. please be careful!

What does it taste like?
TheCheese9921 in reply to alcesteAug 24, 2006. 8:28 PM
it tastes like kombucha
arwen (author) in reply to alcesteDec 15, 2005. 3:43 PM
It depends on your particular batch (proportion of ingredients, whether you use honey or sugar, type of tea, how long it's been brewing)...The best ones I've had taste a little like a light apple cider, or an almost fruity/flowery tea. It's a little bit bubbly as well, particularly if you bottle it after it's done. The commercial ones I've had taste pretty vinegary to me. Apparently the longer you leave it, the more sour (and less sweet) it gets.
bonnie says: Jun 18, 2006. 8:20 PM
Someone said to store the Kombucha in a ziplock bag with the tea in the fridge. NEVER store in plastic - it leaches. ALWAYS use glass containers. Here is how I store it(for the past 7 years). In a small glass container, i put the mushroom and enough liquid to cover it, I then put a thin, white cotton cloth over it and keep it closed with a rubber band. Put it on the top shelf in the fridge and add more tea as it evaporates. IT IS VERY IMPORTANT that you do not store this or drink it in plastic. I only use glass - not crystal.

Hehe, I think I made some of this on accident one time. Never thought to actually taste it! I'm a big tea drinker, so I'll have to try it.
Katie says: Mar 27, 2006. 5:41 PM
I live in the Bay area and was hoping you could 'hook up' a starter. I'm not sure how to email you, but you can email me at xveganxdanceparty@hotmail.com. thanks!
reviks says: Mar 10, 2006. 3:02 PM
also if you are using a ceramic vessel stay away from reds or greens as they might be copper based glazes and the acidic quality of the kombucha could leach the metal out of the glazes as well as compromise the glaze surface, such as etching it which would make it more difficult to keep sanitary.
manchego says: Mar 2, 2006. 11:30 PM
It is very important to sanitize anything that comes in contact with the kombucha. The kinds of mold or bacteria that ctould contaminate the culture are potentially fatal. The odds are low that you would foul up your batch and drink it without noticing, but it's possibly and much more likely if you don't santize your fermenting vessel and stirring implements. Iodine sanitzer is a good choice, it's cheap and non-toxic when dilute. Also, some people like to ferment in ceramic vessels for some kind of feeling of authenticity. Make sure that the ceramic does not have any lead based glaze! The kombuch is quiet acidic and it leaches metal out of the glaze. A good rule of thumb is to use glass and never let any metal touch the culture itself with the possible exception of high quality stainless steel for short periods of time. That said, the drink is delicious once you become accostumed to the flavor. I recommend adding a little bit of juice (whatever flavor suits your fancy) after the initial fermentation period, then bottle and let it sit for a few more days. Then you have a sweet and fizzy drink that is incredibly refreshing when chilled.
mhuckaba says: Feb 28, 2006. 7:21 PM
Should you refridgerate the tea after its done brewing? Should you filter out the solid particles? Are there any health risks?
arwen (author) in reply to mhuckabaMar 2, 2006. 12:41 AM
If you want it to get fizzy, you should actually keep it in a bottle with a cap in a warmish place for a few days until the bottle is hard. It tastes nicer chilled after that, I think, but it's not dangerous to leave it out. If you leave it too long, though, it starts to form a new skin and get more sour. Filter out the solid particles if it grosses you out, but don't bother otherwise. As for health risks....there are as many as with anything you ferment (beer, yogurt, whatever). It seems pretty safe though, as long as you're careful to keep everything clean. If you seen ANY mold, though, toss the batch. The only sicknesses reported had to do with mold (according to wikipedia). I don't know anyone that's had any problems, though.

phinch says: Dec 15, 2005. 11:58 AM
How do you maintain the starter? Do you need to feed it sugar every once in a while? It seems to me that the starter would run out after a while.
arwen (author) in reply to phinchDec 15, 2005. 3:41 PM
Yeah, you do need to feed it. After you harvest it, you give it a fresh batch of sweet tea to work on. I'm not sure what happens if you leave it with the same batch for a long time...haven't tried that. There are a couple of good websites with more info in them if you want to do some research:

http://www.kombu.de/ (with pages in 29 languages!!!)

and

http://www.kombucha.org/

I know if you want to slow growth or let it hibernate, you can keep it in a tupperware container with a little bit of liquid in the fridge....
phinch in reply to arwenDec 15, 2005. 8:44 PM
cool. Is the end product alcoholic?
arwen (author) in reply to phinchDec 28, 2005. 3:31 PM
it's mildly alcoholic, but I think kids drink it, so it's not really something you can get drunk off of...
