„hou fajiao; 后发酵 - Post-fermented. 后hou - behind, after. 发; fa - has many meanings; to develop, expand, bring into existences, start; rise or expand when fermented. 酵 jiao - fermented. Together 发酵 means to ferment. Confusion often arises as the term fajiao is used to refer to both processes of fermentation and oxidation. The more specific term yang hua - 氧化 refers specifically to oxidation.“

„Poor control in fermentation/oxidation process can result in bad ripened pu'er, characterized by badly decomposed leaves and an aroma and texture reminiscent of compost.“

„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“
