5 Things to Know About Parmigiano-Reggiano

1. The 80- to 90-lb wheels of cheese designated as Parmigiano-Reggiano must only be made by approved producers. They are made by traditional methods that have been used for more than nine centuries.

2. We choose to have our Parmigiano-Reggiano aged for 24 months—longer than most. We think this has the best balance of flavor, texture, and aroma. The wheels are carefully aged in special rooms where they are cleaned and kept at specific temperatures and humidity.

3. As the cheese ages, peptones, peptides, and free amino acids form. When these crystalize, they give Parmigiano-Reggiano its distinctive, slightly crunchy texture, as well as making it a healthy, easy to digest food.

4. After aging for one year, professional cheese testers from the Parmigiano-Reggiano Consortium scrutinize each wheel for maturation, aroma, color, consistency, and internal structure. After passing inspection, the wheel is branded with the Consortium's symbol and finishes aging.

5. Once a wheel is opened, it's susceptible to oxidation, like a fine wine, and should be wrapped in clean plastic wrap. Store in the warmest part of the fridge and never freeze.
