Taetea 8592 was successfully developed by Menghai Tea Factory in 1985. Originally created as an exclusive supply for the Hong Kong South Tian Trading Company, it was requested by South Tian to stamp a purple “天” character on the cotton paper packaging. This led to its colloquial name among Pu-erh tea enthusiasts as the “Tian Character Cake” or “Purple Tian Cake”. 8592 is known for its large, robust leaves, offering a rich and mellow aged aroma with high sweetness and a smooth texture upon tasting.

The tea cake is well-shaped with moderate tightness, featuring thick and robust leaves with a slight presence of golden tips. The liquor is bright reddish-brown, exuding a pronounced sweet aroma with sugary notes. Its taste is sweet, mellow, and well-balanced, providing a smooth mouthfeel. The leaf base is red-brown in color, showcasing coarse and robust leaves with a noticeable stem presence.
