Puer Tea Glossary - Zhi Zheng Tea Shop

„sheng; 生 - Raw, uncooked, un-processed. Here used to refer to Puer tea that is made from maocha that does not undergo further processing, other than steaming and pressing where it is made into cake, brick, etc. form.“

„Good quality old tea has a 'matured' fragrance (chen wei). This comes from tea that has been stored well and matured without any adverse effects. (xing wei - a 'fishy' smell that can be detected in old tea that has been stored poorly - should be clearly distinguished from chen wei which is quite different). “
