Hi! There's a good recipe for kombucha in Eat Fat Lose Fat by Mary Enig and Sally Fallon - same recipe in Sally Fallon's Nourishing Traditions. I would contact a chapter leader of the Weston A Price Foundation (westonaprice.org) to find out about getting a kombucha culture locally. I've saved s much money making my own kombucha (and I like the taste better, too!) Happy New Year!!!
You can find a culture at kombu.de - I would happily send you one but I'm in the states and who knows what they'd so with it at the border?
Also I priced it - homemade costs about 20 cents a pint and at Fairway in NYC it costs between $3. and $3.50 a pint! And I like the taste of homemade better. Little learning curve, but worth it. The culture reproduces itself every time you make a batch. Enjoy!!!
