Kımız is a dairy product formed through lactic acid and ethanol fermentation, typically made from mare’s milk. It is a slightly sour, frothy drink. During its production, alcohol fermentation occurs, and the alcohol content ranges from 1.10% to 1.75% (Ö. Kınık et al., “Research on Kımız Production and Characteristics,” Food, 2000, 25 (5), p. 382). Depending on the type, the alcohol content of kımız can reach up to 3% (Hasan Yaygın, “Characteristics of Kımız and Health-Related Properties,” Food, 1991, 16 (2), p. 112).
Since Islam prohibits intoxicating beverages, kımız, which may intoxicate if consumed in large quantities, is considered impermissible, even with a low alcohol content. While some sources state that kımız with a low alcohol content does not cause intoxication, it is essential in Islam to avoid doubtful matters. Therefore, it is advised to abstain from such drinks. As a result, drinking kımız is expressed as not permissible.
