Soft cheeses need to be refrigerated at all times. However, some types of harder cheese can be left at room temperature for short periods of time.
Some of the many types of soft and semi-soft cheese include American, Brie, Gorgonzola, ricotta, curd, and Fontina. Hard cheeses include Romano, cheddar, Parmesan, and Asiago.
Cheeses that need to be refrigerated should be kept at temperatures of 35 to 40 degrees Fahrenheit. The shelf life of cheese is extended when wrapped properly. Cheese can be frozen, but it is not a recommended storage method. Freezing cheese can change its texture and make it harder.
