From my understanding the culture eats up some of the caffeine when culturing the tea.  The drinkable kombucha only has small amounts of sugar and caffeine in it.   I use green tea which has less caffeine in it.  The instructions I got with my culture said you can use either green or black tea.  It also said you can use herbal teas but you can't keep the culture going on herbal tea alone.  Every other culture you would want to use a caffeine tea and keep a healthy culture solely on green or black tea in case the one you are using on your herbal teas stops culturing.

I've started brewing Kombucha, but I'm not thrilled with the idea of drinking caffeine so I was wondering if herb teas could be used instead of green or black tea. Failing that, what about white tea? Thanks.
