Of all the generic black tea I've tasted (India, Ceylon, Turkey, Kenya), Kenya tea is actually my favorite, although it's one of the cheapest.
Last week at a friend's home I had some trader joe organic black tea bag (that 365 something brand). It's probably the best teabag I've ever tasted, better than some low level loose leaf tea. But the package doesn't say where the tea is from. I was very much impressed by the teabag and has written whole food to ask for the production location of the tea. I very much suspect it's from Kenya.
