Airag is the fermented beverage from mare’s milk. This element includes a traditional method of making airag, its related equipment and objects such as khokhuur (cowhide vessel), buluur (paddle) and khovoo (kibble), and associated therewith social customs and rituals. The milking season for horses runs from mid June to early October. Daily milk yield of mares varies from 3 to 6 liters. The basic technique of making airag consists of milking mares and cooling fresh milked milk, and repeatedly churning milk in a khokhuur with starter left inside to assist its fermentation. The liquid must be churned 5000 and more times to make good fermented blend of airag. Mare’s milk undergoes fermentation by lactobacilli and lactic acid streptococci, producing ethanol, lactic acids and carbon dioxide. The airag - mildly alcoholic white beverage emits a delicious smell and its pleasant taste can make your mouth watery. For making the khokhuur, first, the cowhide is soaked and hide’s filament is removed, then it is dehydrated in the wind and fumigated. In such process, the cowhide turns to a white flexible leather. The khokhuur is made from this white leather and consists of mouth neck, corner, body and cords. The buluur is long-handled wooden paddle which is used for churning airag in khokhuur and furnished with bored blade of board at the end. Khokhuur can hold 40 to 100 liters of airag. Airag is used and served as a main and holy drink during various fests and in making offerings and ritual blessings.

The libation ceremony starts with horses are gathered and brought to the tethering line at sunrise. At first, the first-born foal is caught and hitched to the tethering line. When catchers finish tethering the foals, they place their lasso poles in row at the back of the ger. All gathered people can then enter the ger and have tea. Then they go out of the ger, where upon the milking of mare begins. The first mare is milked by a man. This is vistage of ancient tradition. After milking the mares, a milk libation ceremony is performed. The general proceeding is the same as other feast proceedings. But their contents are different. It reflects the manner and movement of tethering foals or colts and mare's ferment milk-libation.
