Traditional yak herding in Mongolia: the source of Byaslag’s unique flavor and nutrition.
What is Byaslag Cheese?
Byaslag (pronounced byas-lag) is a mild, unripened cheese made from the milk of yaks, cows, or sometimes sheep and goats. It is a cornerstone of Mongolian cuisine, especially among nomadic herders. The cheese is typically white, slightly crumbly, and has a clean, milky flavor with a hint of tang from the fermentation process. Unlike many Western cheeses, Byaslag is rarely aged and is often enjoyed fresh or sun-dried for longer storage.

History and Cultural Significance
Cheese making in Mongolia dates back over a thousand years, rooted in the nomadic lifestyle of the Mongol people. Byaslag is traditionally made in a ger (yurt) using yak or cow milk collected from herds that roam the vast steppe. The process is a communal activity, often involving several family members and passed down through generations.
Byaslag is more than food—it's a symbol of hospitality, sustenance, and survival in Mongolia’s harsh climate. It is served to guests with tea, eaten as a snack, or used in rituals and celebrations. The cheese is also a practical solution for preserving milk in a land where refrigeration is rare and mobility is essential.
How Byaslag is Made: Traditional Methods
The process of making Byaslag is simple but requires skill and patience:
- Milk Collection: Fresh yak or cow milk is collected, often mixed with a small amount of kefir or yogurt to act as a natural starter.
- Curdling: The milk is gently heated over a fire. As it warms, the starter culture causes the milk to separate into curds and whey.
- Draining: The curds are scooped into a cloth and allowed to drain, sometimes pressed between wooden boards with a weight to remove excess whey.
- Shaping: The cheese is shaped into flat rounds or blocks. It can be eaten fresh, or sun-dried for a firmer, longer-lasting product.
Unlike many European cheeses, Byaslag does not use rennet. The use of kefir or yogurt as a curdling agent gives the cheese a subtle tang and supports gut-friendly bacteria.
Nutritional Profile and Health Benefits
Byaslag is a nutrient-dense food, providing essential protein, calcium, and healthy fats. Because it is made from yak or cow milk, it is rich in:
- Protein: Supports muscle repair and growth, especially important for active lifestyles.
- Calcium: Essential for bone health, teeth, and nerve function.
- Vitamin B12: Important for energy and brain health.
- Healthy Fats: Yak milk is higher in omega-3s and conjugated linoleic acid (CLA) than cow milk, which may support heart health.
- Probiotics: The fermentation process introduces beneficial bacteria that support gut health.
Byaslag is naturally low in carbohydrates and, when made from yak milk, may be easier to digest for some people with lactose sensitivity.
Byaslag vs. Other Cheeses
How does Byaslag compare to more familiar cheeses?
- Texture: Byaslag is firmer and less creamy than mozzarella, but softer than hard cheeses like parmesan.
- Flavor: Mild, milky, and slightly tangy—less salty than feta, less sharp than cheddar.
- Production: Made without rennet, using only milk and natural cultures.
- Storage: Can be eaten fresh or sun-dried for months, making it ideal for nomadic life.
