Post-fermented Teas Hei Cha 黑茶

Dark tea (Hei Cha 黑茶) is post-fermented tea, which means that after the tea leaves are oxidized after harvesting, they undergo accelerated controlled fermentation. For accelerated fermentation, the wet layering process ((Wo Dui 渥堆) is most often used, when biochemical reactions occur under the influence of microorganisms. In oxidation, biochemical reactions occur when interacting with atmospheric oxygen and typically last for several hours. The fermentation process can take several hours to several months, but can then continue without limitation for decades.
