Finding a source that isn't so vague about how to start a first batch. Most recipes I see have sugar, tea and vinegar. Now the hard part I'm finding is what's used to ferment? I keep reading about "mother", kombucha "mushrooms" and kombucha "culture". But that doesn't tell me a whole lot. Where do I get this? Is it like vials of yeast similar to that for homebrewing beer? I've seen "kombucha" tea in my local grocery store, do these teabags include the yeast culture to start fermentation? Any help would be appreciated, I'd like to get the ball rolling!
