Kombucha Heritage is the non-alcoholic program at Ủ. Developed through tea, time, and controlled fermentation, each batch forms its own balance of acidity, aroma, and texture.

The name Heritage reflects a continuity. Tea has long been part of Vietnamese taste — shaped by region, season, and time. Through fermentation, that foundation is extended into a new form. Because the process remains active, no two batches are ever exactly the same. Variation is part of the character — not something to be corrected.
