Puerh History - Pu-erh.Net

„At the beginning of 1990s, many small tea factories were born. Some of them started to use class level 3 (or even higher) raw tea (which was only available for emperors in the past) instead of level 6 (or even lower) raw tea (which was the traditional material for producing 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".“
