Rượu cần is a variety of Vietnamese rice wine that is usually made with glutinous (sticky) rice, though plain rice, millet, or cassava can also be used as a base. Unlike similar varieties, this type is not distilled, and the rice is usually combined with various herbs, spices, and roots before it is left to ferment for several weeks.
The process is traditionally done in large earthenware pots, which are covered with banana leaves. Rượu cần holds ceremonial value in Vietnam, and it is mostly enjoyed during ceremonies and festivities. The pot is usually placed in the center, and the wine is slowly sipped with the help of long bamboo straws.
