Kumis is a fermented dairy product that originated in ancient Mongolia, but over time it has spread throughout Central Asia. The drink is similar to kefir, but is traditionally produced from mare’s raw milk, which contains more sugar than goat’s or cow’s milk, and it is also rich in proteins and vitamin C.
Due to the amount of sugar in mare’s milk, kumis has a higher level of alcohol than kefir when fermented. If distilled into the spirit, kumis becomes araka or arkhi. This light-bodied dairy drink has a slightly sour flavor and an aftertaste reminiscent of almonds.
