Pu-erh tea

„Pu-erh is typically made through the following steps:
1. green/raw 青普: sun fixation 曬青 > rolling 揉捻 > sun drying 曬乾:
2. dark/ripe 熟普: sun fixation 曬青 > rolling 揉捻 > Wo Dui (piling) 渥堆 > sun drying 曬乾:
3. added processes: green and dark pu'er can be compressed/shaped into cakes and aged.“

„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).“
