Shou Puerh
Shou (熟) puerh, often called "cooked", "ripe", or "black" puerh, is produced through a process called "wet-pile fermentation" (wo dui, 渥堆), which ferments the tea before being compressed. During this process, the tea is piled, moistened and then covered with thermal blankets to increase and maintain internal heat. The result is a dark, full-bodied brew with a relaxing energy.
