Tobacco fermentation / curing chamber for cigars

Tobacco fermentation / curing chamber for cigars
Tobacco is an age old, yet amazing plant, which has become increasingly popular among hobbyist in recent times!

Perhaps it is a distraction from daily stresses and allows an escape to simpler times. For some, growing tobacco is an absolute obsession...and its easy to see why! Tobacco starts from shockingly tiny seeds and grows a million fold into a 6-7 foot monster in just about 5 months. You too can join the ranks of tobacco plant enthusiasts and with some luck and planning, your efforts may be rewarded with a homegrown cigar!

Growing and harvesting is a perquisite to fermentation covered in other guides, available here . This instructable picks up after you have air cured your green leafy bounty and is one possible way to simulate the needed conditions for fermentation at home. **Tobacco sowing season is NOW! March-June,get started TODAY!**

This project was created last year (2008 harvest) to provide address a common question in the tobacco growing hobby, discussing the critical points of curing tobacco. Also provided is an example of how one may be able to affordably recreate the conditions needed for tobacco fermentation. No oil heaters required!

Step 1Before we start...

Before we start...
Before starting here's a small note of discretion: Typically tobacco growing hobbyist raise and cure these plants for the pure enjoyment of taking care of this fast growing monster! There is great potential for a wonderfully cured crop at the end of the growing season, however this hobby shouldn't be taken as a way to save on your tobacco spending money as there is a lot of time and labor invested with a lot of potential for crop failure due many factors: both while growing then the potential of mold during the curing process!

On the plus side: Home grown tobacco contains far less chemicals and no additives when compared to the stuff the tobacco industry produces. Buuut, it is still good to note the same surgeon general warning that "smoking is bad for your health", etc.

That being said, lets get started! Whoo-hoo!

when air curing has happened with my plants there are vast diffrents in colour between the diffrent leafs some are dark brown - light brown but some are a very dark green.. they are cured they just seem to hold there colour..? mayb to much nitrogen locked in the leaf... what do you think

im in manchester uk.. i have tried drying in about 4 diffrent places now over 2 years .. i dried that lot in the loft so there was temp fluctuation. and all so i listened to my mums idea of putting it between news paper which was silly thing to do, it stuck to the sheets of paper and when mouldy! proberly down to the paper.. the best way i found was hung up in a garrage. it was cold and had good air flow. i will try outside next year just abit worrie about things eatting them .. the slugs around here seem to have a nicotine addiction.
this pic is just a couple of late bloomers that iv put in a pot outside if you notice on the dried leaf there is type of mould when cured outside have you had this proble befor or has this happened because its still attached to the plant?
has not been a good year for growing this year but the other plants were about 5ft with broard leafs what was left after the slugs

i hope this works because all my tobacco is in there.. iv got a brewing heat pad about 30 watts put a storage box on top will 2 lt of water. some plastic corks to keep the purple basket out of the water - filled the purple basket with the tobacco and put quite a thick bit of plastic over the top the plastic has been stretched and taped in place.. it has all been cleaned because this sort of condition breeds mold.

Pretty inventive set-up you have there. How did the tobacco smoke after it was finished curing ?

curing tobacco is very simular to aging wine
if you make red wine then drink it straight away it is not nice
but leave it for 6 months it takes on a new flavor but leave it for 1yr -1yr 1/2 its is proberly the best it will be...

Thanks for the upload- I feared an indoor fire too, when I saw the articles they had on these things already! had to settle on polystyrene sheets in the end tho, those coolers are rare and expensive over here! suprised that a 30W bulb would be capable of generating the right heat tho? was considering the use of a computer fan in the base, after all, cool air and a medium heat source is how a food dehydrator works ; ) let me know what you think
Nov 23, 2011. 11:34 AMandybuda says:
a masons thermometer had temp and humid and are very cheep.. for the heat source .. a brewing heat pad could be used that gives of a gentle heat...

Ahh, I see. Thank you for the information here, its inspired me to make a few useful mods to the chamber idea I had in mind ; )

Just a thought: there are some devices used for pet reptiles that might give off the same heat without being as potentially dangerous. They even have heating elements that screw into light bulb sockets. I'm not an expert though, so I can't say for sure if it would work or not.

True, also you can use a computer fan with adjustable speeds to control humidity. I've seen a chamber built out of one of those Rubber Maid standing plastic cabinets, with a reptile heater at the bottom and the shelving cut out and covered with screens to hold the plant material. The guy also used a thermostat to control the heat. It worked very well. I intend to build one myself.

The fermentation chamber I saw also had a hygrometer mounted in the door so better observe temperature and humidity

To me the way you have this all set up is nothing more then a fire hazzard. Now I do think I have a better way to accomplish this process. Which I am getting from my experience with raising tropical reptiles and snakes. It would be slightly more expensive but the concept is entirely the same.

What you would need is a fish take with a lid. The lid can be a screen lid for if you think that you need to remove some of the ventalation from the chamber. You simply need to take tin foil or plastic wrap and wrap the lid.

Now for say jackson chameleons who require just about the same conditions as you are describing. They do like it slightly cooler but they do love the extra humidity. So what I would do instead of wrapping the screened in lid is I would simply add a second clamp lamp and or maybe a strip floresent light with a day light bulb. This would take away some of the extra spaces allowing the humidity to escape. Also instead of a 30 watt bulb I would use atleast a 90-150 watt incadecent bulb.

This give you the heat source you would need to keep it around the temps you are talking about. Then for the moisture you just need to either set up the tank with either a water dish on one side. When the water evaporates out you simply need to add more water to this dish and you are all set.

I have not tried this my self yet since I recently decided to start growing my own but I will be taking my knowledge of keeping tropical reptiles alive and mixing it with the process you are talking about. Also I want to note that if you are noticing that your cured leaves are getting slightly to dry simply make sure that you place the light over the water and not over the leaves. This way you are not forcing them to dry out but instead giving them the humidy and heat from the water. It will make the water evaporate alot faster but to me this sounds like it would be a much safer and reliable solution.

If any one feels like trying my method out please feel free to contact me and let me know if it works while I wait for my first plants to grow.

i have used a heating pad that is for home brew before.... they can take abit of humidity/damp and a towel on top can control the temp (distance from heat source) the one i have is only 30w but is about 1ft x 1ft

not a good year for growing tobacco in the uk this year... the plants got eaten alive.... but i got lots of seeds for next year.. what i did get from the plants i also ruined by drying them in news paper and not checking them... for drying i should have hung them up in a cool dry place i find this works best. so they don`t dry to quick but this way can be prone to mould growth hence the area has to be dry...

Surf Monkey Coconut: I purchased some Havana seeds from you a few months ago and I am eager to plant them. This sounds like fun and if all goes well ill be able to enjoy my work.

I do have a question, would the fermentation process be able to take place in a food dehydrator?

Also could I use an aquarium with the temperature maintained and do the same thing by putting the tobacco leaves in a bag misted with water?

How long does it take for the fermentation process to complete? How do you know when the process is complete?

Well, I just ordered some seeds from your ebay store (didn't see the link above). I saw this a while back, and thought "man, I wish tobacco would grow up here in upstate NY". Last year, I had a friend that had six beautiful plants (I think Connecticut variety) growing in his back yard. He definitely proved me wrong.

Since I didn't get a jump start on it over the summer like I told myself I would, I'm going to give hydroponics a try. I have an amazingly sunny apartment, and a home grown hydroponic garden, so why not? The only downside is that I'll have to cut back on my lettuce, cucumbers, and tomatoes in order to make space... or maybe I'll start another garden.

I think it's worth a little experimenting. If you have any tips for hydroponics that don't come in your little booklet, I would be happy to hear them.

Hopefully, I can figure out the whole fermentation thing when the time rolls around.

what kind of conditions would be best to dry your tobacco in? and can you skip this step if you want to use the tobacco in a pipe or something like that?
Jul 29, 2011. 6:39 PMmatt_and_nick says:
i didn't know that tobacco had to be fermented first. i thought you just dried it.
also, i was wondering is it IS possible to somke a just picked leaf (would it hold an ember?)

Surf Monkey, how do I know when the leaves are "just enough" air dried and not too much? I tried growing tobacco and my leaves turned to paper, which promptly molded. That's no good!

No plastic bag,there no oxigen. No oxigen _ no oxidacion_no fermentation

I have to wonder if another kind of smoke-able plant would benefit from this process? Nice article, btw.

Excellent setup!...I'm about to prime my small home "plantation" and your instructions seem to fit my needs! However, I was wondering about your fermentation process - do you "rotate" the stacks of leaves/hands regularly (as I've read on some sites) to prevent rot or mold?
