This is the third Guoyan raw pu-er that I've tried, and I've loved them all. It comes entirely from Ban Zhang mountain, which, I take it, is one of the famous pu-er producing mountains in Yunnan. To limit the bitterness, I kept the first three infusions very short: about 5 seconds. Far from bitter, each was extremely sweet though the characteristic smokiness of a young raw pu-er was there too. There was a fruity flavor too, though it was hard to pick out among the others.
