About five years ago I bought a Japanese tea called Yabukita in a commercial tin at a Korean store and not cheap $10/100g. I couldn't find anything on it using the popular web search engine of the time and thought the taste average but not good. I checked a couple of days ago and all the specialty Japanese tea websites are goo-goo-gah-gah about it and more expensive than I paid. I tried it again and damn if it wasn't one of the best Japanese greens I've had in a long time. I tried multiple infusions and the thing I noted the leaf was actually disintegrating each time and I hadn't seen that in any other tea. It made a cloudy brew but tasty green cup which was more pungent than floral after the first. Now I have to limit myself till I can find more on the shelves. It's been awhile since I've been to that Korean store.

PS Maybe it was longer than five years because the first post about it is June 23 1999 and I don't remember seeing it with DejaVu.
