Is Pu 'er tea raw or cooked?

Pu 'er tea has both raw tea and cooked tea.

1, Pu 'er raw tea. Natural oxidative fermentation. Sun-drying of big leaf seeds, whether it is pressed tea or loose tea formed by high-pressure sterilization, is essentially Yunnan green, that is, green tea before oxidation. Tea polyphenols have high content, astringent taste and strong irritation. After a certain period of storage, the oxidation degree of tea polyphenols decreased, and the taste tended to be mellow and better, similar to Pu 'er tea in history.

2. Pu 'er cooked tea. Microbial fermentation. Pu-erh cooked tea is Pu-erh tea which is fermented at high temperature, also called artificially fermented Pu-erh tea, or modern craft Pu-erh tea. In order to meet the demand of consumer markets in Hong Kong and other places, and solve the problem of long fermentation time after natural fermentation of Pu 'er tea, Yunnan began to develop fermentation technology in 1973, and successfully trial-produced fermentation technology in Kunming Tea Factory in Yunnan in 1975.

After artificial water splashing and heap fermentation, Dianqing crude tea is rapidly fermented for 40-60 days under the action of microorganisms and hydrothermal, and it becomes Pu 'er cooked tea without storage, that is, it has an old, fragrant and mellow flavor.

Pu 'er tea is a kind of tea that has been stored for a long time. The longer it is stored, the better it tastes. Although Pu 'er tea has a long shelf life, it cannot be stored for a long time.
