How Long Do You Age Parmesan Cheese?

Parmesan cheese is a beloved Italian cheese known for its rich flavor and crumbly texture. One of the factors that contribute to its unique taste is the aging process.

But how long do you age Parmesan cheese? Let’s dive into the details.

The Importance of Aging

Aging is a crucial step in the production of Parmesan cheese. It allows the flavors to develop and intensify, giving the cheese its distinctive taste. The aging process also contributes to the texture, making it firm and granular.

So, how long should you age Parmesan cheese?

Minimum Aging Period

In Italy, there are strict regulations regarding the minimum aging period for Parmesan cheese. According to these regulations, Parmigiano Reggiano, which is the original Parmesan cheese, must be aged for at least 12 months. This ensures that it reaches a certain level of maturity before it can be labeled as true Parmigiano Reggiano.

Extra-Aged Parmesan

If you prefer a stronger and more intense flavor, you can opt for extra-aged Parmesan. This type of Parmesan is aged for over 24 months. The longer aging period allows the flavors to deepen even further, resulting in a more complex and robust taste.

The Aging Process

During the aging process, Parmesan cheese goes through several stages of development. In the first few months, it undergoes enzymatic changes that break down complex proteins into simpler forms. This contributes to the development of flavor compounds.

As time goes on, moisture evaporates from the cheese, resulting in a firmer texture. The longer the cheese ages, the drier and more crumbly it becomes. This is why aged Parmesan is often grated or shaved rather than sliced.

Storage Conditions

To properly age Parmesan cheese, it needs to be stored under specific conditions. The ideal temperature for aging Parmesan is around 55°F (13°C).

The cheese also needs to be kept in a well-ventilated area with controlled humidity. These conditions allow the flavors to develop gradually over time.

Proper Wrapping

When aging Parmesan cheese, it’s crucial to wrap it properly. The traditional method involves wrapping the cheese in a cloth made of natural fibers such as linen. This allows the cheese to breathe and prevents excessive moisture buildup.


  • Avoid plastic wrap or airtight containers, as they can trap moisture and hinder the aging process.
  • Regularly check the cheese for any signs of mold or spoilage.

The Joy of Aged Parmesan

Aged Parmesan cheese is a true culinary delight. Its intense flavor and crumbly texture can elevate any dish, from pasta to salads to soups. Whether you prefer the classic 12-month-aged Parmigiano Reggiano or the bolder extra-aged variety, there’s no denying the joy that comes from savoring this magnificent Italian cheese.

So, now that you know how long you should age Parmesan cheese and how it enhances its flavor and texture, get ready to embark on a journey of taste by indulging in this remarkable culinary treasure!
