Pu-erh tea

„Maocha can be sold directly to market as loose leaf tea, compressed to produce "raw" Sheng Cha, naturally aged and matured for several year before being compressed to also produce "raw" Sheng Cha or undergo Wo Dui ripening for several months prior to being compressed to produce "ripe" Shou Cha.“

„This process was first developed in 1972 by Menghai Tea Factory and Kunming Tea Factory] to imitate the flavor and colour of aged raw pu-erh, and was an adaptation of wet storage techniques being used by merchants to falsify the age of their teas. Mass production of ripened pu'er began in 1975. It can be consumed without further aging, though it can also be stored to "air out" some of the less savoury flavors and aromas acquired during fermentation.“
