Pu-erh is a sub-category of Dark Tea that comes from Yunnan province in China. They can be strong teas. They may also be medium-bodied, bright, and slightly sweet depending on how you prepare them. Pu-erh teas typically are aged and are prized in China for their medicinal properties and earthy flavor. Pu-erh can have an earthy, rich, and dark flavor. It can also be sweet and floral with a tingling sensation.

Pu-erh tea has an active (probiotic) bacteria that deepens the flavor of the tea over time. In theory, the older it is, the better and more valuable it becomes.

The specifics of aging Pu-erh are closely guarded trade secrets.
