Learn To Make Kombucha
The first step in brewing kombucha is to obtain a scoby. When you get your scoby, make sure the person gives you at least a cup of kombucha as well.
Once you have your scoby, you'll want to keep it in the fridge in the kombucha it came in until you're ready to use it. Store it in glass if at all possible; plastic can leach into the kombucha, and metal is reactive with its acids.
To brew your kombucha you need:
* 3 1/2 quarts of filtered water--the chlorine in tap water can hurt your scoby! Filter the water through a Brita or other water filter, let it sit out overnight to let the chlorine evaporate (happy thought, no?) or use bottled water. Doesn't have to be distilled, just non-chlorinated.
* 1 cup regular old white sugar
* 5 regular old black tea bags--you can get as fancy as you like with the tea, but I use garden variety restaurant supply tea bags. Red Rose, Lipton, whatever. AVOID ARTIFICIALLY FLAVORED TEAS like Earl Grey or Constant Comment. If you want to experiment with flavor, try different kinds of tea like green or white, or substitute a bag of herbal or spice tea for one of the black tea bags. I like putting in a bag of Yogi Tea. Just make sure the bulk of the tea is camellia sinensis--the plain old tea plant--in some form.
* A large pot
* A gallon-sized glass jar
* A piece of cloth that will cover the top of the jar
* A rubber band or something similar that is big enough to go over the mouth of the jar
* Your scoby and at least 1/2 cup of leftover kombucha from your last batch
