Rðợu nếp (sometimes also called rðợu nếp bắc, or rðợu nếp cẩm, ) is a pudding or drink from northern Vietnam.
It is made from glutinous rice that has been fermented with the aid of yeast and steamed in a banana leaf. It may be either deep purplish-red or yellow in color depending on the variety of rice used. Rðợu nếp is mildly alcoholic (rðợu is the word for "alcohol" in Vietnamese). Depending on its consistency, it may be considered either a pudding or a wine. Thicker versions are eaten with a spoon, while more liquid varieties may be drunk as a beverage. Rðợu nếp than is a brown-colored rice wine.
Many Vietnamese people regard rðợu nếp as a healthful food, and believe that it wards off or kills parasites.
Although they are most typical of northern Vietnam, rðợu nếp and rðợu nếp than are available in Ho Chi Minh City, at the market near the residential quarter where northern Vietnamese people live.
In Vietnam's Central Highlands, a similar rice wine, rðợu cần (literally "stem wine" or "tube wine"), is drunk in a communal manner, through long reed straws out of large earthenware jugs. Rðợu cần may be made out of ordinary rice, glutinous rice, cassava, or corn, along with leaves and herbs. Yet another variety of minority rice wine is rðợu nếp nðáng, made from a glutinous rice grown in mountainous cultivation areas of Vietnam's northwest.
A similar dish, from southern Vietnam, is called cám rðợu, and consists of balls made from white glutinous rice in a mildly alcoholic rice wine.
