Traditional Kazakh fermented mare milk is a tangy, mildly effervescent dairy beverage enjoyed for centuries by nomadic herders on the Central Asian steppe. It is naturally fermented using lactic acid bacteria and yeast, producing a refreshing sour flavor with subtle fruity notes and a very low alcohol content. This homemade version uses fresh mare's milk and an active starter culture to recreate the authentic taste of the Kazakh steppes.

Ingredients
For the fermentation
- 1 L (about 4 cups) fresh raw mare's milk, strained through cheesecloth
- 1/4 cup (60 ml) active kumis starter culture or live kefir grains
- 2 tablespoons plain live yogurt with active cultures (optional backup)
Equipment and finishing
- 1 large stainless steel or glass bowl, sterilized
- 1 clean wooden or plastic stirring spoon
- 1 muslin cloth for covering
- 1 glass jar with loose lid for second fermentation
- Cold filtered water for dilution (optional)
Directions
- Sterilize your bowl, spoon, jar, and any equipment by pouring boiling water over them and air-drying them completely; residual soap or detergent can kill the live cultures.
- Pour the fresh strained mare's milk into the sterilized bowl and warm it gently to about 25-30°C (77-86°F) by sitting the bowl in a larger pan of warm water; test with a clean finger, it should feel neutral, not hot.
- Whisk in the kumis starter culture (or kefir grains) thoroughly so the bacteria and yeast are evenly distributed throughout the milk.
- Cover the bowl with the clean muslin cloth to keep dust out while still allowing airflow, and let it rest at room temperature (20-25°C / 68-77°F) for about 18-24 hours; stir gently with the wooden spoon every 4-6 hours to keep the top from separating and to distribute the fermenting cultures.
- When you see fine bubbles rising and the milk tastes tangy but not sharp, transfer the milk into the sterilized glass jar, close the lid only loosely, and refrigerate for 6-12 more hours to slow the fermentation and develop the characteristic light fizz and gentle sourness.
- Stir the finished fermented mare milk one final time, taste for balance, dilute 1-2 tablespoons of cold water per cup if it feels too strong, and serve very cold in small ceramic bowls or glasses as Kazakh tradition prescribes.
Cook’s Notes
- Mare's milk is naturally lower in fat and higher in lactose than cow's milk, which is why kumis ferments quickly and tastes subtly sweet-sour; if you must substitute, goat's milk is the closest match but the flavor will be different.
- Keep the temperature steady during fermentation; too cold and the yeast won't activate, too warm and the milk may turn overly sour or develop off-flavors.
- Traditional Kazakh kumis is unpasteurized and contains live cultures and trace alcohol (0.5-1.5%); pregnant women, young children, and immunocompromised individuals should consult a doctor before consuming.
- Stop fermentation earlier (around 12 hours) for a milder, sweeter drink, or let it go longer for a tangier, more effervescent result with higher alcohol content.
- Serve in a traditional Kazakh wooden bowl (piyala) or a small glass over ice, and pair with fresh bread, dried fruits, or savory dumplings for an authentic nomadic-style spread.
