Cold brewed this today like I threatened. It’s much nicer this way, and if it’s ever on sale again I might pick some up just for this purpose. There’s still a slight bitter note at first, but then that mellows out into a smooth flavor with a sweet berry taste. It doesn’t quite manage to taste natural but it’s certainly more interesting this way.
Unfortunately my opinion of this one is slightly influenced by the good oolong I had before it (which I can’t find on here because the label is completely in Chinese). Not sure it works as an oolong exactly, but it’s interesting as a flavored tea.
