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.“

„The fermented dark tea, Hei Cha (黑茶), is one of the six classes of tea in China, and pu-erh is classified as a dark tea (defined as fermented), something which is resented by some who argue for a separate category for pu-erh tea.“
