Pu-erh tea

„Unlike green tea produced in china which is dried with hot air after the pan-frying stage to completely kill enzyme activity, leaves used in the production of pu-erh are only pan-fried and thus a small amount of enyzmes are left which contribute a minor amount of oxidation to the leaves during sun-drying“

„shai qing; 晒青 - Sun dried. This is a critical aspect of Puer Tea processing. Oven dried tea is considered inferior to sun-dried. The Provincial Government has ruled that Puer tea must be sun-dried.“
