Unopened cheese can last a long time depending on the type and how it is stored. Hard and semisoft cheeses, such as cheddar, Parmesan, and Swiss, can last for up to 6 months when stored properly in the refrigerator. Soft cheeses, such as Brie, feta, and goat, can last up to 4 weeks. Unopened processed cheese, such as American and Velveeta, can last up to 2 months.

Can you eat unopened cheese past expiration?

Generally speaking, it is not recommended to eat unopened cheese past its expiration date. Once the expiration date has passed, the cheese may have lost its original flavor, texture, and nutritional value. The expiration date is a best-by date that indicates when the cheese is at its peak flavor, so eating it after the expiration date may not result in the best eating experience. Additionally, eating spoiled cheese can lead to food poisoning.
