Our USDA certified Organic Gunpowder Imperial is the highest grade available and comes from the renowned green tea triangle in Anhui Province, China. Called "gunpowder" due to it's pellet like appearance, not all gunpowder green tea is the same. For the finest quality look for a consistent size, shaped in a roll, a dark, almost shiny finish to the leaf, and a smoother, not as smoky a finish as some of the lower grade teas.
