This came in a “Black Teas” sampler, so I wasn’t expecting any pu-erhs, nor did I really know what this was. It was not labeled with anything expect “Pu-Erh Yunnan Black.” Is it a black tea made with pu-erh material? Is is a blend of pu-erh and black?
After tasting it, I’m still not sure. It’s a shu possibly mixed with a black tea. Leaves are broken and don’t look live they’ve ever been compressed into a cake. Dry leaves smell of sweet hay, brewed leaves smell like a damp barn: woody, eathy, damp leaves, horses.
Brewed in a clay gaiwan with just under boiling water. Not a lot of flavour but no bitterness either.
