Thanks to Charles Thomas Draper for mentioning this sheng. I bought a sample (cakes are very expensive) and immediately fired up my little pot and steeped it three times: at 30 seconds, 1 minute, and 2 minutes. The first steep was exquisitely smooth, with a light camphor taste and a more pronounced mandarin orange flavor. Things got pretty wild on the next two steeps; the orange remained, and was joined with chestnut and what reminded me of a perfect black bean sauce. This is a high energy tea that had me buzzing along way into the night, right through an excellent set by the Futurebirds at the Press Room in Portsmouth, NH. I’m going to try and conserve this tea; as good as it is now, it will be even better when some of the bitterness fades away over time.
