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.“

„Smokiness
The art of making tea from ancient tea trees is very old. Hand-roasting is not easily mastered. Any slight error will influence the taste of the tea. Smokiness or yan wei is one example but it should be distinguished from a burned flavour which is described as hu wei. The latter, typically arises when tea is not well roasted and is, unfortunately, not uncommon. Yan wei or smokiness is caused by oven drying. “
