Ingredients

  • Fresh mare's milk (or a substitute such as cow's milk for a home approximation) — 8 cups (1.9 litres / 64 fl oz)
  • Existing airag or a live kefir/yoghurt starter culture — 1/2 cup

Method

  1. Warm the milk gently to just above room temperature.
  2. Stir in the starter culture thoroughly.
  3. Transfer to a clean container (traditionally a leather bag) and churn vigorously and repeatedly over the course of the day.
  4. Leave to ferment at a moderate temperature, churning periodically, for 24–48 hours until slightly sour and mildly fizzy.
  5. Strain if needed and serve chilled or at room temperature.

Introduction: A tangy, mildly effervescent fermented drink made from mare’s milk, deeply tied to Mongolian nomadic culture and summer festivities.

Cultural Background: Airag has been central to Mongolian herding life for centuries, traditionally churned in a leather bag and shared generously among family and visitors, especially during Naadam and summer gatherings when mare’s milk is most plentiful.

Tips: Frequent churning is essential — it develops the characteristic light effervescence of properly made airag. True airag is made specifically from mare’s milk; other milks will ferment but produce a notably different result.

Variations: A related drink, tarag, is made similarly from cow’s milk and is more commonly replicated at home. Serve airag alongside bansh or buuz as part of a traditional summer meal.

Storage: Store in a sealed container in the refrigerator for up to 5 days, though flavour and effervescence are best fresh.

Reheating: This drink is served cold or at room temperature and is not reheated.
