The process used to convert mao cha (raw puer tea) into ripened Pu-erh is a recent invention that manipulates conditions to approximate the result of the aging process by prolonged bacterial and fungal fermentation in a warm humid environment under controlled conditions, a technique called wòdūi (渥堆, "wet piling" in English), which involves piling, dampening, and turning the tea leaves in a manner much akin to composting.
The tea is weighed and placed in the bucket. Then it will be steamed for 25 seconds to soften the leaves and to allow the leaves to stay together when pressed.
Cloth is placed over the bucket and the tea is emptied in to the cloth. Then tied the cloth.
Put the wrapped teacake to the machine to be pressed.
