The 2004 aged pu-erh is the tea made in 2004. The material is from the old tea tree, naturally growing in the Bao Dao Shan high mountains of West Yunnan, where the altitude is around 2000m. The tea has rich quality content itself. Now in 2019, fifteen years has passed. The ideal keeping condition in Yunnan has made the tea transform very well. The liquor of it is red now (close to that of cooked pu-erh tea). And it gives off matured sweet flavor. The taste is very mellow tasty and rich!
