You guys win, I'll stop being lazy and try to grow a SCOBY. Did 4 cups water, 2 black tea (allegro brand) bags, 1/3 cup sugar, and 8 oz of GT's with the baby SCOBY thing in it. Got that going in a 1/2 gal jar. I also got an aquarium heater that should keep a water bath around 76-80 deg f, because my house has been around 60. I have 6 six 1/2 gal jars, so I'll probably start another in a couple days and see if one does better. My hesitation was that some people claim they had trouble after the reformulation of commercial kombucha to minimize alcohol.
