Trà Sen Hiền Xiêm is a family-run artisanal brand from Hanoi’s Tây Hồ district, recognized as one of the most respected guardians of the traditional technique of infusing green tea with fresh lotus petals. Their production relies entirely on manual craftsmanship - from harvesting lotus flowers at dawn, to carefully separating the petals, and repeatedly layering fine tea leaves with the fragrant “gạo sen” pollen over several days.
