Da Ye Zhong(大葉種)
Da Ye Zhong translates as “big-leaf variety,” and the name is accurate. Unlike the small-leaf Camellia sinensis var. sinensis that predominates across most Chinese and Japanese tea regions, Da Ye Zhong is Camellia sinensis var. assamica. Wider leaves, bigger buds, more caffeine, more catechins, more body.
Yunnan is where Da Ye Zhong is at home. The province's subtropical climate and the native presence of assamica tea plants, some of the oldest tea trees in the world growing wild on Yunnan's southern mountains, make it the backbone of Chinese tea. Almost every puer you will ever drink, sheng or shou, is Da Ye Zhong. So is every Yunnan black tea. Dian Hong, the honey-sweet red tea from western Yunnan, is Da Ye Zhong. Yue Guang Bai, the moonlight white, is Da Ye Zhong processed as white tea.
What the cultivar delivers: a thicker, rounder mouthfeel than sinensis teas, stronger body, a characteristic sweetness that lingers in the throat (huigan). The leaves are large enough that a well-made cake can be unfolded and studied. A gushu sheng puer cake from a village like Laobanzhang can show intact leaves longer than a thumb.
Gushu (古樹, old-tree) describes the age of the tree, not a different cultivar. Da Ye Zhong grown on wild, semi-wild, or ancient plantation trees, three to eight hundred years old and sometimes older, produces tea materially different from the same cultivar on young bush plantations. Deeper roots, more terroir expression, richer chemistry. The price difference can be an order of magnitude.
