Pu'erh tea, also spelled pu-erh or puer, is a type of fermented tea that is made from the leaves of the Camellia sinensis plant. It is produced in the Yunnan province of China and is known for its bold, earthy flavor and dark color. Pu'erh tea is made using a process called post-fermentation, in which the tea leaves are left to age and ferment after they have been dried and roasted. This process gives pu'erh tea its unique flavor and aroma, and it is believed to contribute to the tea's potential health benefits. Pu'erh tea is traditionally consumed in China, and it is becoming increasingly popular in other parts of the world due to its bold flavor and potential health benefits.
