The taste of fresh blueberries is intense with a slight astringency, a  trait common to most dark berries. The green gunpowder leaves are steamed as soon as they are plucked and then hand-rolled into small round pellets. Once immersed in water, these pellets gracefully open  to reveal a full leaf.  Gunpowder teas typically have a dark coppery green color, and produce a pale yellowy green infusion, with  a smooth, slightly smoky cup with a sweetish finish. Incidentally, this is one tea that goes well over ice.
