This is a delicious tea from Guizhou. Guizhou is not one of the better-known tea growing provinces outside of China. However, it is highly respected in China. Guizhou is famous for its high mountains and deep valleys. The soil this tea is grown in is high in zinc and selenium, which some experts believe gives this tea extra medicinal qualities. Besides the fact that these teas are delicious, they also tend to stay fresh longer because the leaves are ball-shaped.
