You can figure out a recipe using my rule-of-thumb guidelines:
Guideline for container: Use a glass container for brewing. I use gallon pickle jars, but only filled so the depth of the liquid should be about equal to the diameter of the liquid's surface.
Guideline for water: The water you use should be chlorine-free. I boil tap water to achieve this. Distilled water does not have enough minerals in it for good fizz.
Guideline for tea: I use 5-6 tea bags per gallon of water (minimum 1.25 tea bags per quart), almost always part green tea (or all) green tea. The balance should be a black tea. If you use all black tea, you are making Russian Kombucha. I think GT's is made with all green tea.
Step 1 : boil water in glass or stainless steel, take it off the heat, put tea into it. Cover and let it sit awhile. I just let the tea cool with the teabags in it because the kombucha moms like the tannins.
Guideline for sugar: I use 1/3 C ordinary granulated white sugar per quart of water.
Step 2: Fish out the tea bags and dump in the sugar. Stir until sugar dissolves.
Guideline for starter: The starter (finished kobucha) must be at least 10% of the liquid. Example: if you are making 2 quarts of tea, use 3 tea bags, 2/3 cup of sugar, and at least 6.4 ounces of starter (32 oz + 32 oz + 64 oz, so figure 6.4 oz of starter plus a little more because you just added 6.4 oz to the brew, making it 70.4 oz. So use at least 7.1 oz starter...or 8 or 9 or...) If you harvested you last batch too early and it was still a bit sweet, add extra of it if you use it as starter. The starter's job is to acidify the tea enough that bacteria is kept at bay until the SCOBY forms on the liquid's surface.
Step 3: dump in enough kombucha (starter) to equal 10-20% of the total liquid.
Step 4: Be certain that the liquid is no warmer than room temperature, then put it into the glass container with the mom.
Step 5: Cover container with a napkin, hankie, or paper towel and secure with a rubber band.
Step 6: Wait at least 7 days before tasting. The new SCOBY (mom) will form on the surface--it will be 3/16" thick or more by the time the brew is ready for harvest. Brew will have some tartness to taste and will foam a little if stirred. I usually have to wait about 10- 14 days; sometimes longer.
Step 7: Save some of the brew for your next batch. Drink the rest, or bottle by filling containers very close to the lip; cap tightly. Nicest taste and fizz for me is about 3 weeks wait.
