In the high-altitude communities of Xizang, a frothy, savory drink has sustained generations and forged social bonds for centuries. Butter tea, known locally as po cha, combines fermented black tea leaves, yak butter, and salt into a uniquely nourishing beverage that reflects the region's adaptation to its environment.
A Recipe For Resilience
Prepared by churning hot tea with butter and salt in wooden cylinders, this high-calorie drink provides essential energy in Xizang's oxygen-scarce plateau climate. The traditional brick tea base—historically transported via ancient trade routes—develops deep earthy flavors during fermentation, balanced by the richness of yak butter.
More Than Sustenance
Butter tea's role extends beyond nutrition. Serving it in homes signals respect and hospitality, with hosts continuously refilling guests' bowls. In Lhasa's tea houses, the drink fuels lively discussions and community gatherings, preserving oral traditions and social networks.
Modern Cultural Symbol
While urbanization introduces new beverages, butter tea remains a proud cultural marker. Annual festivals feature ceremonial preparations, and younger generations reinterpret the drink through sustainable yak dairy initiatives. For visitors, tasting this distinctive brew offers insight into Xizang's enduring heritage.
