It's a late first post of the day for me as well. Had my usual start with Yunnan Gold, two infusions, one of which went cold as I left it too long. But it was still really good. Then there were a few blending experiments.
As for books, I have a few around here but can only think of The Tea Lover's Companion
Has anyone heard of a two volume tea encyclopedia kind of thing? I cannot remember the name of it but it was an big older set that had recently been republished....
