What does airag taste like?

Airag has a slightly fizzy texture and a tart, sour flavor softened by a hint of sweetness. People new to it often find it very sour at first. Because it keeps fermenting, taste can change from batch to batch, and it is especially refreshing when served chilled.

How strong is airag?

The alcohol content generally ranges from 2 to 3 percent by volume, which is mild. The exact amount varies with fermentation time, so treat it as an alcoholic drink if you are driving or avoiding alcohol.

How is airag consumed?

  • Cold: best served chilled as a refreshing drink.
  • From a bowl: guests are greeted with a bowl of airag.
  • As hospitality: the bowl is a symbol of hospitality and respect at gatherings such as weddings and festivals like Naadam.
  • In summer: herders traditionally milked mares in summer, when the animals were well fed and healthy, so that is when most airag was made.

What is airag made from?

Mare’s milk, fermented. Fermentation turns some of the milk sugar into lactic acid and a little alcohol, which is what gives the sourness, the slight fizz and the low alcohol content.

Tips if you are offered airag

  • Start with a small sip. It is sour and can be rich.
  • Local customs vary, so watch your host and follow their lead.
  • People who are pregnant, avoiding alcohol, or have milk allergies should skip it.
  • Bottled airag from shops will not taste exactly like homemade versions; flavor differs between producers.

Is airag the same as kumis?

They are the same kind of drink. Kumis (or koumiss) is the name used in other Central Asian countries for fermented mare’s milk, while airag is the Mongolian name.

Can you make it at home?

We do not recommend making it at home without expert guidance, and we did not verify where it can be bought outside Mongolia.
