Puer Tea Glossary - Zhi Zheng Tea Shop

„tong feng; 通风 - air-flow. Puer should be stored somewhere where there is a little air movement - it doesn't need to be much. Even if it is quite humid, the airflow will guard against tea developing mould. However, care should be taken that tea is not stored in a draft which will dry the tea tea out.“

„The process used to convert máochá into ripened pu'er is a recent invention that manipulates conditions to approximate the result of the aging process by prolonged bacterial and fungal fermentation in a warm humid environment under controlled conditions, a technique called Wò Dūi (渥堆, "wet piling" in English), which involves piling, dampening, and turning the tea leaves in a manner much akin to composting.“
