Philippine rice wine, popularly known as tapuy, is an alcoholic rice drink. The name is derived from tapai, a fermented rice dish found in most of Southeast Asia. It is a traditional beverage originated from Banaue and the Mountain Province, where it is used for important occasions such as weddings, rice harvesting ceremonies, fiestas and cultural fairs. It is produced from either pure glutinous rice or a combination of glutinous and non-glutinous rice together with onuad roots, ginger extract, and a powdered starter culture locally known as bubod.
The characteristics of tapuy, as in many other rice wines, depend on the process and ingredients used by each manufacturer. However, in general, tapuy is a clear full-bodied wine with a strong alcoholic flavor, moderately sweet and often leaves a lingering taste. The alcohol content is 28 proof or about 14 percent. It has no sulfites (which are preservatives found in other wines) that sometimes cause adverse reactions like hang-over and allergies. Tapuy is also not diluted with water and has no sugar added.
The process of producing commercial tapuy starts with weighing and washing selected rice. Then, the rice is cooked, cooled and inoculated with a natural starter culture, locally known as bubod. After that, a process of natural pre-fermentation and natural fermentation follows. Once the fermentation is completed, the fresh wine can be harvested and pasteurized. After the pasteurization, the rice wine is aged, filtered and clarified before bottling. Finally, bottled rice wine is pasteurized once again before sealing.
