Just thought I'd share a pic of my 2 1/2 gallon SCOBY and brew, Denver, started by a dear friend and jazz musician several years ago from a bottle of GT's. He passed it along to me when he moved to Denver to pursue his music. I have passed out many babies from this one.
To make 2 1/2 gallons I use 15 bags of organic oolong tea, 2 1/2 cups organic sugar. I bottle in Grolsh bottles, usually unflavored, but leave it out for a day or two to get fizzy before storing in the fridge. I always brew my sweet tea the night before I bottle so as soon as I bottle I can dump in room temp tea and start it fermenting right away.
