It’s a dark, wiry tea. Very reminiscent of a Yunnan, but also reminds me of the one Taiwan black I’ve tried. Dusty, doesn’t really seem to have many notes. Perhaps cocoa (dry, not chocolate). I think I can get what they mean by “smoke”, but nothing that makes me think maple.
I’ve had it a few times already, both in a mug and in a gaiwan. I was gifted with another variety of it, which I haven’t tried yet, but that I think I should steep side-by-side.
