More Kombucha

More about kombucha...

A little more about the SCOBY, and how to make your own. The SCOBY is a gelatinous mass of yeast and bacteria that forms when conditions are right. While many people obtain their first SCOBY from online/mail order options or from friends who may be brewing their own kombucha, it is quite possible to grow your own - and not difficult. It's just a little time-consuming.

You can read the article that I read here (this is a great website with lots of info on natural foods in general, by the way). But I will also share my experience in growing my own SCOBY.

First, I bought some G.T.'s Original Raw Organic Kombucha at Hannaford. You should be able to get by with one bottle, but I was drinking it then, and had more on hand.

Next, I made sweet tea as described in the article at the website, but I made 2 cups of tea, sweetened with 2 tablespoons of white cane sugar.

I had an empty G.T.'s bottle, so once both the newly made tea and the G.T.'s Original Kombucha were at room temperature, I combined them in my 4 cup Pyrex measuring cup and then poured the combined liquid into each of two empty G.T.'s bottles about 3/4 of the way full - so that there was the maximum amount of surface space I could get.

Then I covered each with a square of paper towel and fastened them with rubberbands. Now, it would have been better - possibly even faster - if I had put the liquid into a container with a larger diameter, but I worked with what I had at the time, having read that the starter SCOBY needed to be thick, but the diameter didn't really matter that much.

Finally, I put them into the cupboard above my pilot lit gas wall oven, where it was much warmer than anywhere else, and I waited.

A new SCOBY forming rather resembles an oil slick when it starts. There is nothing to indicate that it is anything more than a slime coating on the top of the liquid... you just have to wait. Time is the last ingredient in this recipe.

At first, I was convinced that I had a moldy SCOBY forming on one of the containers, because it looked like there was something dark forming on part of my slime. But everything I read stated that mold looks like dry greenish black mold and this didn't look like that. Since I had two of them going, I figured I would just wait and see, and if it turned out to be mold, I had the other one.  It took well over a week for one of the SCOBYs to resemble the SCOBYs that I'd seen in pictures, but once it did, it was just a matter of waiting for it to thicken up. What had appeared to be mold turned out to be a brown clump of yeast waste - yucky looking but perfectly normal in this kind of culture. After a bit over two weeks, it seemed almost done - but I waited a little longer for it to thicken a little more. When that first one got to be over 1/4 inch thick, I gathered the stuff I had to try to make a batch of kombucha with my new SCOBY.  I left the second one, which seemed much thinner, in the jar and ignored it for another few days.

That one came out even thicker, in the end.  I can't really remember how I managed to get three, as I really do only remember starting two - but I did get three by the time all was said and done. I now have three healthy SCOBYS that I rotate by the length of time since they've been used - the older ones being first used. I keep them in ceramic bowls, covered with the tea they were cultured in, with the bowl covered with plastic and stored in the fridge.  The refrigeration slows the activity of the SCOBY so they will last. They can be kept in the fridge for a couple of weeks, but much longer than that and you risk them starting to die off.

Next up, how I made kombucha with those thick, gelatinous masses!

No kitties, Kombucha!

So ... about kombucha. Kombucha is fermented tea. It's an ancient Asian drink and is available at many health food stores and even some grocery stores like Hannaford. There are many supposed health benefits, but the main ones are lots of pro-biotics (good for the digestive system) and lots of B vitamins (likely due to the yeast).

If you've ever had hard cider, I think that the taste is similar, but less sweet. There are "hard iced teas" on the market, but I don't think that the flavor is very like those. And, yes, as a fermented beverage that starts out with sugar, it does contain a very small amount of alchohol - but a lot of that is dependent upon how long you ferment it.

I decided to embark on making my own due to the fact that the cost of the stuff I like is about $3.70 per 16 ounce bottle. I looked into it online and found a number of different sites and blog entries devoted to the brewing of kombucha. It sounded simple enough - tea, water, sugar and time ... except that I would need a starter culture, sometimes called a Kombucha mushroom, but more technically and accurately referred to as a "SCOBY". S.C.O.B.Y stands for "Symbiotic Culture Of Bacteria and Yeast" and is exactly that. You can buy a SCOBY online for anywhere from $15-$30, but I was leery of all these little individual sites and researched if there was a way to make my own.

Sure enough, there is! It's a little time-consuming, but it's relatively inexpensive, and the three that I grew have made me several batches of kombucha and ensure that I can rotate them so they can rest a little between batches... and I always have one backup. The cool thing is that they grow their own replacements - a "baby" that you can separate from the "mother" when the baby is thick enough.

Here is a list of the things you would need were you to decide to brew your own kombucha:

• LOTS of black or black and green teas (there are some that believe some black tea is essential for a good kombucha - who am I to argue that?) - preferably organic and it's great if you can find affordable free-trade tea. I found organic black and green teas at Hannaford.
• White cane sugar. Can be organic if you prefer, but my understanding is that the sugar is almost completely consumed by the fermentation process, so most people aren't as picky about this. Other sweeteners may be iffy - honey, for example, has natural anti-bacterial properties and so might kill the bacterial part of your culture, ruining your kombucha. Probably best to stick with plain white cane sugar especially to start.
• SCOBY plus some starter tea - generally included if you purchase a SCOBY online.  If you grow your own, you will have the leftover tea from that starter. And you will always save some kombucha from each batch you brew to protect your stored SCOBY and use as starter tea for a new batch.
• At least one, prefereably two, 1 gallon glass jar(s). I purchased 5 litre canning jars online - they were pricey - or at least the shipping was high, but they fairly sturdy.  You might be able to find gallon or larger glass jars at a restaurant if you know anyone who might be willing to save them for you.  Or, if you purchase in bulk and can find glass jars that large, and don't mind eating a lot of pickles or whatever before you can use them ...
• Cheesecloth (I triple layer it for better protection from flies and such), a square or two of muslin or other breathable but fairly tight weave cloth large enough to hang a couple of inches over the mouth of your jar(s). Some people use a lint free kitchen towel.
• Rubberbands. Several. Large enough to go around the mouth of your jar and whatever material it is you cover it with. Just get a package of them so you have plenty of them when you get going - eventually they will stretch out and break, and you'll want to have more to replace broken ones.
• 1 -2 quart Pyrex or other heat resistant bowl or measuring cup.  I have both, but am now mostly using my 4 cup Pyrex measuring cup. The measuring cup can be used in both the preparation process and the bottling process, so it might be your best bet.
• Tea kettle or small stainless steel stock pot.
• Six to eight 15-16 oz bottles. If you already drink a commercially sold kombucha you can sometimes use those bottles - especially if they have screw on caps. Or you can do what I did and buy bottles ... or what I really did was buy a case of Grolsch beer in the flip top bottles and drink or discard the beer for the bottles. It is actually cheaper to buy a case of Grolsch and pour the beer down the drain to get the bottles than it is to buy the bottles online and pay for shipping. Shipping glass is EXPENSIVE.
• A funnel that will fit into the necks of your bottles. Still tricky, but the funnel truly helps in bottling.
• Plastic straws. I have a little dispenser similar to the old fashioned straw dispensers one used to find in the old soda shops - this keeps them clean and protected in storage. You will want to use the straws to help sample your kombucha during the fermenting process to see if it's at the point you would want to bottle it yet - i.e., taste-testing.
• A quiet, warmish (70-85 degrees F) space big enough to hold at least one, if not both, of your gallon jars, and possibly 3 or more of your bottles. I use the top of my fridge right now, but I'm thinking I will need to rearrange the area over my wall oven - mine is an old oven with a pilot light, so there is always a little bit of heat rising from it. The warmer the area, the faster your fermentation will take place.

So ... there is a little investment in time and equipment/supplies if you really want to brew your own kombucha. While you can do it in smaller containers, that means more SCOBYs, so the gallon container is ideal. Two containers means you can start a new batch before the first one is finished. I haven't quite gotten that timing down yet, but I'm hoping to at some point have batches overlapping by 3-4 days so that I never run out. I have already saved a bunch of money by cutting my dependence on store-bought kombucha in half if not further, and I am hoping that I get a routine that will enable me to only purchase from the store when I need an infusion of new culture into my kombucha family.

I will write more about how I grew my own SCOBY and how I brew and bottle my kombucha in future blog posts... I hope you are interested and enjoying the read!
