Pu-erh tea shapes

„Pu-erh shape - Mushroom - Literally meaning "tight tea," the tea is shaped much like túocha, but with a stem rather than a convex hollow. This makes them quite similar in form to a mushroom. Pu'er tea of this shape is generally produced for Tibetan consumption, and is usually 250g or 300g.“

„The fermented dark tea, Hei Cha (黑茶), is one of the six classes of tea in China, and pu-erh is classified as a dark tea (defined as fermented), something which is resented by some who argue for a separate category for pu-erh tea.“
