The Portland Tribune recently reported on the exploits of Steve Lee, who was involved with the founding of Stash Tea and later Tazo Tea. Lee's current project is Kombucha Wonder Drink.
KWD's Web site describes it as "a refreshing organic sparkling fermented tea". For those of you who are not familiar with kombucha, there is also an FAQ at the Web site that should help bring you up to speed.
I actually had an experience with kombucha some years back, courtesy of a coworker who was quite fond of the stuff. He convinced me to take a crack at making it, a process that basically consists of using a bit of starter culture to ferment and make your own.
Memory's a tricky thing and I have to confess that I don't recall the result of this adventure. Something tells me that the brew-in-progress got tossed after while because my better half felt that it was thoroughly nasty. Or maybe it was me who felt it was thoroughly nasty. But to tell you the truth, I don't recall. I guess I'll have to give it another try sometime.
