Yes, a piece of work indeed, it doesn’t even have the right to be called a tea. It’s so incredibly tart that it’s unpleasant to drink. I don’t know what sangria really tastes like, but if it’s supposed to be this tart, then they did a good job. There is no berry taste in this tea at all; usually the berries sweeten things up, but the tartness from I-really-don’t-know-what takes over. Overall, it’s just one big cup or tartness; no other way to describe it.
