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.“

„There is also knowledge that you can gain from drinking the same tea over and over again that you cannot from sampling. This may involve the tea changing on you – a traditionally stored puerh gradually losing its storage taste, for example. Or, it can just be that you start noticing nuances that were there, but were not necessarily obvious the first few times you try it.“
