It's been fun tasting these samples. Have been trying them variously -- a few times in a gaiwan, and also in a couple of favorite yixings I use for puerh. I've done all the sessions 'blind' (not knowing which tea I was brewing until after I'd exhausted the sample) except for the first round. So interesting, the differences each time. The only teas I could guess correctly each time were the 2007 Blue Mark and the 2003 ZiPin. I found the Blue Mark to have a distinctly deep and highly focused warmth in the core of the chest as well as consistently high marks all around for aroma, body, balance, etc, and the ZiPin would always give itself away with it's strong overall qi. I thought the 2003 Qing Teng showed a good deal of activity, as well. All of the samples, though, have been a pleasure to try. Thanks again for the opportunity!
