Tepache

Tepache is a fermented beverage made from the peel and the rind of pineapples, and is sweetened either with piloncillo or brown sugar, seasoned with powdered cinnamon, and served cold. Though tepache is fermented for several days, the resulting drink does not contain much alcohol. In Mexican culinary practice, the alcoholic content of tepache may be increased with a small amount of beer.

In Mexico, tepache is usually sold as a chilled drink by street vendors. It is usually stored in barrels to make the fermentation process faster. It is served either in a clay mug or in a clear plastic bag with a straw inserted for easier travel. In the U.S., it is sold in juice bars or traditional Mexican restaurants in the Mexican American communities of the Southwestern United States. The fermentation process for making tepache is simple and quick, which makes tepache a drink readily produced at home.

Tepache is fermented by different microorganisms. Bacteria, such as Lactobacillus pentosus, L. paracasei, L. plantarum, L. lactis and yeast from the genus Saccharomyces have been found in tepache.
