Wow, I have no idea what that is! The description says Black Tea, but the photo seems to show some green parts like an oolong or a light darjeeling. It doesn't look like shu puerh, but I suppose it could be a sheng puerh, but I can't imagine why anyone would call that a black tea. Is there anyone there who can provide guidance about brewing? The good news is that it doesn't seem like something that would have strange stuff in it ... no rats' tails or insect bits!
It may be time to experiment.
