Theme - Tea oxidation

„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.“

„The leaves are then dry pan-fried using a large wok in a process called "kill green" (殺青; pinyin: shā qīng), which arrests most enzyme activity in the leaf and prevents full oxidation. After pan-frying, the leaves are rolled, rubbed, and shaped into strands through several steps to lightly bruise the tea and then left to dry in the sun.“

„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.“
