Pu-erh is a type of fermented tea originating from the Yunnan province of China. It is made from the leaves of the Camellia sinensis plant and is known for its unique aging process, which can enhance its flavor over time. There are two main types: raw (sheng) and ripe (shou), each offering distinct taste profiles. The production of Pu-erh involves a complex process that includes withering, rolling, fermenting, and drying the tea leaves. This tea is often compressed into cakes or bricks, making it easy to store and age. Pu-erh is appreciated for its earthy flavor and potential health benefits, including aiding digestion and reducing cholesterol.
