I tried his late 2000 LBZ, those in 100gm beeng. Good quality stuff.
Also tried his mid 2000s pure mountain tea. Not too bad either.
Generally I find his tea quite good and above average especially those earlier ones. I haven't own any tea from him but those that I tried are brewed and shared with me by other tea collectors. Sorry I can't recall the year of the cakes. Just the impression.
