Kumis is a traditional milk beverage of cattle-breeder- nomads, received by lactic acid fermentation. True kumis differs by the strength and is made from mare milk. In old times it was made and kept in a horsehide vessel. For that, the skin from the old horse was taken and sewed up, the cellular tissue inside. The hair was singed and the vessel was smoked and greased with oat. The capacity of such vessels was different from 16 liters to 150 liters. This drink, made in a horsehide vessel, was remarkable by its high gustatory senses and foamy consistence because of the gas abundance.
The quality of kumis depends on the ferment. Until the end of XIX century, it was made from the ferment, prepared at the end of kumis season. During the summer cheese sediment was accumulated on the bottom of the milk-skin, it was then dried and kept until the spring. This ferment was combined with mare milk and buttermilk and a dried horse tendon was put in the vessel.
Since XX century, wheat and barley grains, old kumis were used for the ferment and instead of horsehide vessels people made hollowed out linden vessels. Frequent shaking is the indispensable condition of kumis preparing. Kumis treating was a must before and after the meal. This tradition is kept our days as well and made in different ways.
