Quick Answer: What Is De’ang Sour Tea?
De’ang (德昂族, Dé’ángzú) sour tea (酸茶, suānchá) is made from fermented tea leaves in communities around Mangshi (芒市, Mángshì) in western Yunnan. The finished leaves can be eaten as part of a dish or further processed and dried for brewing.[1]
- Santai Mountain is a documented center of the tradition.[2]
- Sealed fermentation helps give the tea its tart character.[2]
- China added the making tradition to its national heritage list in 2021.[2]
The same English name can refer to a food or a drink, depending on how the leaves are prepared.

If someone offers sour tea, ask whether it will be served on a plate or in a cup. Both uses are part of the local tea tradition.
Two Ways to Serve the Leaves
The edible form uses moist fermented leaves prepared with other ingredients. The drinking form is made by drying and further processing the fermented leaves. When brewed, the infusion can be golden, with a tart taste that gives way to sweetness. A documented Santai Mountain method uses sealed bamboo containers for fermentation. The leaves themselves develop the acidity, a useful comparison with other Chinese fermented foods.[1][2]
Tea in De’ang Community Life
Tea appears in hospitality, wedding customs and ritual among De’ang communities. A creation epic tells how a divine figure brought tea seeds to people. The story gives tea a place in the account of how the community began.[1] The Blang tea traditions of Jingmai Mountain offer a nearby example of how a different community relates tea to its own origin stories and practices.
How the Craft Has Been Passed On
Representative practitioner Yang Lasan (杨腊三, Yáng Làsān) sought out older makers in China and consulted De’ang makers in Myanmar. Families then learned the work through practice with him. The national listing of the local craft and UNESCO’s 2022 inscription of the wider Chinese tea traditions describe heritage at different scales.[3][4]
