Every sip is a new journey – The Mongolian ethnic group's kumis

Kumis, also known as airag, is a fermented alcoholic beverage made from mare's milk by special acidification. Though common among Mongolians, the drink elicits mixed feelings from those trying it for the first time. The drink is so popular among the Mongolian ethnic group that in Japan the soft drink Calpis has already tried to mimic the flavor of kumis.
