Parmesan cheese is a type of hard, granular cheese that has its origins in Italy. It is widely used in various dishes across the world due to its unique flavor and texture. One of the most common questions that people have about Parmesan cheese is how long it is aged for.

What is Parmesan Cheese?

Before we delve into the aging process, let’s first understand what Parmesan cheese actually is. Parmesan cheese, also known as Parmigiano-Reggiano, is made from cow’s milk and has a hard, gritty texture. It has a pale yellow color and a distinctive flavor that can be described as nutty and slightly fruity.

How Long Is Parmesan Cheese Aged?

Parmesan cheese is aged for a minimum of 12 months and can be aged up to 36 months or even longer. The length of time that it is aged for greatly affects its flavor and texture.

12 Months

Parmesan cheese that has been aged for 12 months has a mild, creamy flavor with a slightly grainy texture. It is often used in dishes where you want to taste the other ingredients more prominently.

18 Months

After being aged for 18 months, Parmesan cheese becomes harder and crumblier, with a more intense flavor. It has a nutty taste with hints of saltiness and sweetness.

24 Months

When aged for 24 months, Parmesan cheese has an even stronger flavor than before. Its granular texture becomes more pronounced, giving it an almost crystalline appearance. This type of Parmesan cheese is perfect for grating over pasta dishes or salads.

36 Months or More

Parmesan cheese that has been aged for 36 months or more develops an incredibly rich, complex flavor with a crunchy texture. It is often used as a standalone cheese, rather than being grated or melted into dishes.


In conclusion, Parmesan cheese is aged for a minimum of 12 months, but can be aged up to 36 months or more. The longer it is aged for, the stronger and more complex its flavor becomes.

Whether you prefer your Parmesan cheese mild and creamy or rich and crunchy, there is an aging time that is perfect for you. So go ahead and experiment with different types of Parmesan cheese to find your favorite!
