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.“

„Depending on the desired product and speed, from quickest and tightest to slowest and loosest, pressing can be done by a large heavy stone, carved into the shape of a short cylinder with a handle, simply weighs a bag of tea down onto a wooden board. The tension from the bag and the weight of the stone together give the tea its rounded and sometimes non-uniformed edge. Due to the manual labor involved, this method of pressing is often referred to as: "hand" or "stone-pressing", and is how many artisanal pu'er bǐng are still manufactured.“
