Are there any varieties of cheese that need refrigeration?

Yes, almost all varieties of cheese need refrigeration.

Here's why:

* Moisture content: Most cheeses contain a significant amount of moisture, making them a breeding ground for bacteria. Refrigeration slows down the growth of these bacteria, extending the shelf life of the cheese.

* Fat content: Cheese is high in fat, which can become rancid and spoil at room temperature.

* Flavor and texture: Refrigeration helps preserve the flavor and texture of cheese. At room temperature, cheese can dry out, become crumbly, and lose its delicate flavors.

Exceptions:

* Hard, aged cheeses: Some hard, aged cheeses like Parmesan, cheddar, and Gouda can be stored at room temperature for a short period (a few weeks) due to their low moisture content. However, it's best to refrigerate them for optimal flavor and texture preservation.

* Specialty cheeses: Some specialty cheeses, like certain aged blues, can be kept unrefrigerated for a few days, but this is often not recommended.

General rule: Unless specifically stated on the packaging, it's always best to refrigerate cheese. Keep it wrapped tightly in plastic wrap or wax paper to prevent it from drying out.
