Kumis
Kumis (also spelled kumiss or koumiss or kumys, see other transliterations and cognate words below under terminology and etymology – old turkic: airag kazakh: қымыз, qymyz) mongolian: айраг, ääryg) is a fermented dairy product traditionally made from mare milk or donkey milk. the drink remains important to the peoples of the central asian steppes, of turkic and mongol origin: kazakhs, bashkirs, kalmyks, kyrgyz, mongols, and yakuts. kumis was historically consumed by the khitans, jurchens, hungarians, and han chinese of north china as well.kumis is a dairy product similar to kefir, but is produced from a liquid starter culture, in contrast to the solid kefir "grains". because mare's milk contains more sugars than cow's or goat's milk, when fermented, kumis has a higher, though still mild, alcohol content compared to kefir.
even in the areas of the world where kumis is popular today, mare's milk remains a very limited commodity. industrial-scale production, therefore, generally uses cow's milk, which is richer in fat and protein, but lower in lactose than the milk from a horse. before fermentation, the cow's milk is fortified in one of several ways. sucrose may be added to allow a comparable fermentation. another technique adds modified whey to better approximate the composition of mare's milk.
