These larger, thicker cakes have been preserved in natural storage. The packaging features large rectangular Zhong character, typical of the period. Crafted from coarse, sturdy leaves under the 7682 blend, this represents the final batch produced by the Menghai Tea Factory using antique tea materials, while also being among the first to incorporate experimental fermentation techniques.
