Frequently Asked Questions

What's the difference between expiration and best quality dates for Parmigiano Reggiano Dop?

The expiration date on Parmigiano Reggiano DOP is more about the quality rather than safety. This cheese can last a long time if stored properly. The expiration date is more of a guideline for optimal flavor and texture. As Parmigiano Reggiano ages, it develops more complex flavors and a crumbly texture. However, if the cheese develops mold or an off smell, it should be discarded.

How can I tell if Parmigiano Reggiano Dop has gone bad?

To determine if Parmigiano Reggiano Dop has gone bad, look for any mold growth on the surface, a rancid or sour smell, or a change in texture such as becoming overly soft or crumbly. Fresh Parmigiano Reggiano should have a firm texture, a nutty aroma, and a clean appearance without any visible signs of spoilage.

What are the food safety risks with Parmigiano Reggiano Dop?

Parmigiano Reggiano DOP, being a hard cheese with low moisture content, has a low risk of foodborne illnesses. However, it is still important to store it properly to prevent contamination. Make sure to keep it away from other strong-smelling foods in the refrigerator to avoid absorption of odors.

What are some pro tips for storing Parmigiano Reggiano Dop?

To store Parmigiano Reggiano DOP, wrap it tightly in parchment paper or wax paper, followed by a layer of plastic wrap or aluminum foil to prevent it from drying out. Store it in the vegetable drawer of the refrigerator, where the temperature is more stable. Avoid storing it in the cheese drawer as it can be too cold. If the cheese develops some surface mold, you can simply cut it off as Parmigiano Reggiano is a hard cheese and mold typically does not penetrate deep.

Any interesting facts about Parmigiano Reggiano Dop?

Parmigiano Reggiano DOP is a renowned Italian cheese that has been produced for over 900 years. It is known as the 'King of Cheeses' and is highly valued for its rich, nutty flavor and granular texture.
