I recently had a chance to try a black tea from Yunnan that was quite interesting. It had a sort of faintly smoky Keemun-like flavor that was a bit different than my experience with standard golden Yunnan congou. It was called "golden snail", due to the unusual roll of the leaves. I'm trying to find out what the proper name for it is, but haven't had much luck. The closest I've come in looks is this black Bi Luo Chun from Yunnan sourcing. Is "golden snail" an English term for black Bi Luo Chun? Can anyone suggest any other possibilities?
