Tried this last night... Wicked Weed Black Angel. Pitch black sour, with a peculiar head that seems to be alive in your glass (made me think of a potion bubbling in a mad scientist's lab). Tons of flavor, though the tartness masks most nuances of oak flavor that you get from some other sours. Still, this is good stuff. Rich, but still perfectly fine on a hot summer day. Would drink again.
