Buk is a traditional fermented beverage made from the sap of the palmyra tree. It is popular in various regions of Southeast Asia, particularly in Vietnam and Cambodia. The sap is collected and then fermented with the help of natural yeasts, resulting in a sweet, slightly alcoholic drink. The fermentation process can take several hours to a few days, depending on the desired taste and alcohol content. Buk is often enjoyed fresh and can be served chilled. It is a refreshing drink that is sometimes used in local celebrations and gatherings, showcasing the cultural significance of traditional beverages.
