I'd say Tai Ping Hou Kui is the specific tea that I've taken to reordering regularly. The first 2011 batch I received from Jing Tea Shop this year was excellent.
Today I repeated tea in a different way. I don't usually have the same tea twice in one day, but I discovered an unopened bag of O-Cha Asa-giri in my cabinet. Now I'm testing different ways of brewing it. I made some this morning in my shiboridashi, since the O-Cha website recommends treating it like gyokuro. Then this afternoon I brewed it in my small kyusu, at the same temperature, and it was even better. Next up, since during a heat emergency something brewed at 150 degrees is better than a tea brewed with boiling water (e.g. puerh), I'm going to load up the kyusu with more tea and ramp up the intensity.
