Xinjiang Ayran (Airan): The Salty Yogurt Drink That Cools Every Meal
The first time I was handed a glass of Xinjiang ayran it looked like thin buttermilk with a faint foam mustache. I had just finished a plate of cumin-heavy lamb skewers in a courtyard kitchen in Yining, and the cook set it down without a word. One sip and the whole meal rebalanced — salty, cool, faintly tangy, nothing like the sweet lassis I knew from elsewhere in Asia. In Xinjiang, ayran (locally called airan or sü’t) is the default cold drink next to grilled meat, and once you understand it, you stop reaching for soda.
What Exactly Is Xinjiang Ayran?
Ayran is fermented milk thinned with water and a pinch of salt, then whisked or churned until it turns light and slightly frothy. Unlike the sweet yogurt drinks popular elsewhere, there is no sugar, no fruit, no syrup — just milk, water, salt, and time. The result sits at roughly the saltiness of a tear and the thickness of a loose smoothie. It is served cold, often straight from the fridge in summer or at cellar temperature in winter.
In Xinjiang the drink crosses ethnic lines. Uyghur households make it, as do Kazakh and Kyrgyz families on the northern grasslands, and you will find it bottled in nearly every supermarket from Urumqi to Kashgar. It is the regional cousin of Turkish ayran, the dugh of Iran, and the tan of the Caucasus — a whole belt of salty yogurt drinks running along the old Silk Road.
Why Salt, Not Sugar?
Salt does two jobs. First, it replaces the electrolytes you lose in Xinjiang’s dry, sometimes 35°C summer heat. Second, it cuts the fat of lamb and beef beautifully. A sweet drink on top of a plate of Xinjiang lamb skewers feels cloying; a salty one resets your palate so the next bite tastes like the first.
How Ayran Is Made at Home
The home version is simple. Take plain whole-milk yogurt (or the thick kurut-style drained yogurt common in the south), thin it with cold water until it pours easily, add salt to taste, and beat it with a whisk or pour it between two jugs until bubbles form. Some families churn it in a wooden butter churn, which also lifts the butterfat into a richer foam. Bottled commercial ayran in Xinjiang often adds a little carbonated water for fizz — read the label for qi shui (sparkling water) if you want the fizzy kind.
Fresh vs Bottled
Fresh house-made ayran tastes brighter and less uniform than the bottled kind. In village homes near the grasslands I drank ayran still warm from the morning milking, salted and cooled in a clay jug — nothing in a shop matches it. Bottled versions (brands like Tebiesi or local dairy co-ops) are reliable, last for weeks, and are what most travelers will actually encounter.
Where to Drink Ayran in Xinjiang
You will find it almost everywhere food is grilled. Urumqi‘s kebab streets near the International Grand Bazaar sell it by the glass for about 3–5 RMB. In Yili (Ili) and the Khorgas border area, Kazakh-run cafés pour it alongside koumiss in summer. In Kashgar‘s old town, ask for airan at any noodle shop and it comes in a small bowl next to your laghman.
| Form | Typical price | Best with | Where I’d order it |
|---|---|---|---|
| Fresh house-made | Free (hospitality) | Whole roasted lamb | Grassland yurt stays, Yili |
| Glass, restaurant | 3–5 RMB | Lamb skewers, polo | Urumqi bazaar, Kashgar old town |
| Bottled 1L | 8–12 RMB | Picnic, long drives | Any supermarket |
| Fizzy (carbonated) | 4–6 RMB | Spicy dishes | Convenience stores, south Xinjiang |
Ayran vs Other Xinjiang Drinks
Don’t confuse ayran with Xinjiang milk tea, which is hot, milky, and also salty but served warm as a hospitality drink. Ayran is cold and snack-time. Nor is it koumiss (fermented mare’s milk), which is alcoholic-light and sour in a different way. Ayran is the everyday, kid-friendly, non-alcoholic option — the regional equivalent of iced water, but with character.
Frequently Asked Questions
Is Xinjiang ayran healthy?
Yes. It is a source of protein, calcium, and live cultures from the yogurt, with no added sugar. The salt content is modest — a glass has far less sodium than a bowl of instant noodles. Travelers with lactose tolerance do fine; those sensitive to dairy should sip slowly the first time.
Does ayran contain alcohol like koumiss?
No. Ayran is simply yogurt, water, and salt — no fermentation to alcohol. Koumiss (mare’s milk) is the lightly alcoholic one. If you want a non-alcoholic cold drink, ayran is safe.
Can I buy ayran outside Xinjiang?
Bottled Turkish or Caucasian ayran in international groceries is a close match. For the real thing, some Urumqi brands ship within China via e-commerce; overseas, look for “Tebiesi” or generic “Xinjiang airan” in Central Asian stores.
Is it very salty?
Less than you fear. Proper ayran is savory, not brine. If a shop version tastes too salty, cut it 50/50 with plain cold water — that is exactly what many locals do at home.
