It was labeled as 1998 vintage 8582 when I acquired this tea almost 15 years ago. But in the yearbook “Pu Erh Xin Yun” p. 59 (see books for identification), it was recorded as late 90’s by the Meng Hai Factory:
It was dry-storage when I acquired them, and after 15 years of drier storage in Houston, it was a pure joy to see the cake has matured to such a clean and energetic appearance and obvious more brownish color.
The true excitement came when tasting it: a very clean fragrance that is full of mature woody, cinnamon, tropical fruit, Chinese date, clove, mushroomy – exactly what you can expect from an over 20-years old 8582. The taste is similarly clean, smooth, and a long finish, with some sweetness, and there is still enough robustness and structure that makes the taste very interesting.
