Pu-erh tea

„The process used to convert máochá into ripened pu'er 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 Wò Dūi (渥堆, "wet piling" in English), which involves piling, dampening, and turning the tea leaves in a manner much akin to composting.“

„Indistinct fragrance is, by nature, restrained, hidden and it is only by steeping the tea and then smelling a cup that has just been emptied of tea can one appreciate this fragrance. Alternatively, one can also smell the steeped leaves. “
