Puer Tea Glossary - Zhi Zheng Tea Shop

„shi cang; 湿仓 - wet storage. Storage that is intentionally humid. Done in order to attempt to speed up the ageing process of Puer tea. It has risks associated with it from effectively shortening the 'life' of the tea, having a deliterous effect on the plant constituents - not least the aromatics compounds to ruining the tea altogether.“
