Pu-erh tea

„The most famous variety of this category of tea is Pu-erh from Yunnan Province, named after the trading post for dark tea during imperial China.“

„Pu'er Tea; 普洱茶. That 'Puer Tea' was given this name suggests that historically this kind of tea - post fermented camelia sinensis assamica must have come from the south and west of Puer for there to have been any sense in transporting it through that city. The majority of good Puer tea still comes from the Xishuangbanna region. Puer County itself was not an historically important tea producing region.“
