A very rare tea cake from 1979. This famous Pu-erh tea cake from the Guang Yun tribute teacake series is made to commemorate the trade relationship between the two provinces which used a combination of Yunnan and Guangxi materials. The mellow taste fits the drinking habits of Southern China with a rich aged aroma and a depth of character to the flavor. Great value for its price for a tea this age. This tea is smooth, rich bodied, with hay aroma, and a strong aged tea flavor.
