Koumiss is a traditional fermented dairy drink made from the milk of horses. It is popular among various nomadic cultures, particularly in Central Asia, where it has been consumed for centuries. The fermentation process involves adding specific bacteria and yeast to the milk, resulting in a slightly alcoholic beverage with a tangy flavor and a creamy texture. Rich in nutrients, koumiss is often praised for its probiotic properties, which can aid digestion and boost the immune system. It is typically served chilled and can be enjoyed on its own or as part of a meal, making it a unique cultural staple in regions where it is produced.
