National-level Intangible Cultural Heritage Product
The history of De’ang sour tea is a chronicle of the De’ang people’s survival, migration, and cultural evolution as “ancient tea farmers.” Rooted in ancient times, it was devised by the De’ang ancestors to adapt to their environment and has been passed down to this day through a distinctive “pit‑based anaerobic fermentation” process. More than just a uniquely flavored beverage, it embodies the De’ang worldview, social rituals, and ethnic identity, standing as a living historical and cultural heritage.
