The Primary Ingredient: Water Buffalo Milk
At its core, buffalo cheese is defined by its source: the rich, creamy milk of the water buffalo (Bubalus bubalis). Unlike cow's milk, buffalo milk has a significantly higher fat and protein content, and slightly lower levels of lactose. This unique composition is what gives buffalo cheese its characteristic flavor and texture. For example, fresh Mozzarella di Bufala is known for its pearly white color, elasticity, and tangier, more complex taste compared to the milder, milky-white cow's milk mozzarella.
The Cheesemaking Process: Pasta Filata
The most famous buffalo cheese, mozzarella, is made using the pasta filata or 'spun paste' method. This artisanal process involves several key steps that have been refined over centuries, particularly in the Campania region of Italy. The steps include heating the milk, adding rennet to curdle it, allowing the curds to mature, then heating and stretching the curds before shaping and brining the cheese.
Other Cheeses from Buffalo Milk
While mozzarella is the most internationally recognized, water buffalo milk is used to create a diverse range of cheeses worldwide. These include:
- Ricotta di Bufala: Made from the leftover whey of mozzarella production.
- Burrata di Bufala: Mozzarella filled with a mix of curds and cream.
- Blu di Bufala: An Italian blue-veined cheese.
- Paneer: Often made with buffalo milk in South Asia.
- Sulguni: A Georgian cheese sometimes made with buffalo milk.
Nutritional and Health Benefits
Buffalo milk's high fat and protein content offer nutritional advantages. It has lower cholesterol than cow's milk and can be easier to digest for some due to its protein profile and lower lactose. Buffalo milk also contains beneficial compounds like immunoglobulins and CLA.

The Historical and Cultural Legacy
Buffalo cheese is integral to culinary history, especially in Italy's Campania region. Water buffalo were present by the 12th century, with cheese production following. Mozzarella di Bufala Campana received Protected Designation of Origin (PDO) status in 1996, ensuring its authenticity. More information on its history is available from the Consorzio di tutela Mozzarella di Bufala Campana DOP.
