I'm sure this has been touched on elsewhere, but usually for whatever reasons the best tea's are not certified organic.
Different theories abound for why this is so. I have noticed some better tasting batches with an organic label lately, so there may be a trend towards organic at the high-end, but the rule still seems that most organic tea is mediocre. Although I guess you could say most tea in general is mediocre, or most everything on earth is mediocre (hehe), but in any case, the best tea still seems to be conventionally grown.
As one example, Dragon Well/Long Jing, the mouthwatering best of the best that I have come across had has not been organic, but I've had plenty of mediocre organic batches. Same with sencha.
Personally, I like to buy organic food where I can, but tea I usually focus on taste... would be nice if more is organic, but i'm not going to avoid the best tea because it isn't certified.
