I can't seem to find it right now (!!) but I had a nice recipe for a kind of bare bones mead involving tea from a friend of mine currently out in south america with the peace corps. Bollocks on the lot of it!
At any rate, there are several recipes that involve black tea because it's ostensibly got tannins and other bits for the yeast to eat up. Pick something that doesn't rely on the tea exclusively (I feel like green tea must have less tannin) and it should come out wonderfully.
Who will try to ferment just about anything
