I make kombucha! OK, I did until I got my morning sickness about 9 months ago. I could NOT deal with the SCOBY at that point, so it kinda got neglected. But now that my daughter is a month old and I have a bigger house, I plan on starting up again. Apparently you can grow a new SCOBY from kombucha you already have. http://www.foodrenegade.com/how-to-grow-a-kombucha-scoby/
I haven't tried it yet, but I hope it works.
The way I brewed mine when I was making it was:
1. Make ridiculously sweet organic black tea, and let sit until room temp.
2. Put in large glass jar (with a little of the last kombucha batch), put SCOBY on top, cover with a clean dish towel, and let sit on top of my fridge for 1 week.
3. Bottle it in mason jars, with some extra sugar and some concentrated fruit juice (cherry is my fave). Let sit at room temp. 1 week.
4. Refrigerate and drink at your leisure!
This method makes it a little sweet/not too sour and super fizzy!
