When it comes to cheese, Parmesan is one of the most beloved varieties. Its rich flavor and distinct texture make it a favorite in many dishes.

But have you ever wondered how Parmesan cheese is made? In this article, we’ll take a closer look at the fascinating process behind this delectable cheese.

The Milk

It all starts with the milk. Parmesan cheese is traditionally made from cow’s milk, which is sourced from local dairy farms. The quality of the milk plays a crucial role in the final product, so only the freshest and highest-quality milk is used.

Curd Formation

Once the milk is collected, it undergoes pasteurization to kill any harmful bacteria. After pasteurization, natural whey culture and rennet are added to initiate curd formation. Rennet helps coagulate the proteins in the milk, leading to curd formation.

The Cutting Process

After curd formation, it’s time for the cutting process. The curds are cut into small granules using special knives or wire cutters. This step allows for whey drainage and further separation of curds.

Salt Bath

After cutting, the curds are immersed in a salt bath for several weeks. This salt bath not only enhances flavor but also helps preserve the cheese by inhibiting bacterial growth.

Aging Process

One of the defining characteristics of Parmesan cheese is its long aging process. After being removed from the salt bath, the cheese wheels are stored in temperature- and humidity-controlled rooms for an extended period, usually ranging from 12 to 36 months.

The Curing Room

The curing room provides optimal conditions for aging Parmesan cheese. The controlled temperature and humidity allow the cheese to develop its unique flavor, texture, and aroma. During this time, the cheese wheels are regularly turned and brushed to prevent mold growth and promote even aging.

Grating and Packaging

Once the aging process is complete, it’s time for grating and packaging. The hardened cheese wheels are grated into the familiar fine shreds that we commonly use. These shreds are then packaged in airtight containers to maintain freshness.


In summary, Parmesan cheese is made from cow’s milk that undergoes pasteurization and curd formation with the help of rennet. After cutting, the curds are immersed in a salt bath before being aged in controlled conditions for several months. Finally, the aged cheese is grated and packaged for consumption.


  • Use high-quality milk for best results.
  • The cutting process helps in whey drainage and separation of curds.
  • Aging in controlled environments is crucial for developing Parmesan’s unique flavor.

Now that you know how Parmesan cheese is processed, you can appreciate this delicious ingredient even more when using it in your favorite recipes!
