I got this as a free sample with my order and was quite surprised how much punch it had. The flavor has a perfect level of strength, which is a nice contrast to all the sweet light 2017s right now. The notes are daisy, stone fruits, buttered green beans, and slight char. It gets sharper in flavor each infusion, and also builds up some astringency, but a drinkable dryness. The energy of this tea hits after the session.
