Gunpowder Green Tea in Bulk derives its name from the shape of the finished tea leaves. Gunpowder Green Tea has a dark golden color, roasted or toasted taste with a strong aftertaste lingering in the front palette, and a strong roasted or toasted aroma. When brewed, the teas unfold into large leaves. Uncle Lee's Gunpowder Green Tea is rich in natural fluoride, calcium, and antioxidants, and has only 20 to 30mg of caffeine.
