Pu-erh tea

„‘Ripened’ Shou Cha (熟茶) tea is pressed maocha that has been specially processed to imitate aged "raw" Sheng Cha tea. Although it is also known as cooked pu-erh, the process does not actually employ cooking to imitate the aging process. The term may come about due to inaccurate translation due to the dual meaning of shú (熟) as both "fully cooked" and "fully ripened".“

„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.“
