How Long Does Cheddar Last?
Shelf Life and Storage Tips
Cheddar cheese, one of the most popular and versatile cheeses worldwide, boasts a relatively long shelf life compared to softer cheeses, which is a attribute highly prized by consumers. The expected lifespan of cheddar cheese varies depending on whether it is purchased pre-sliced, in blocks, or shredded, but fundamentally, it is influenced by its storage method and whether the package is opened or unopened. Storage conditions are paramount; ideally, cheddar should be kept in the refrigerator where it can maintain its quality and flavor for a considerable amount of time.
When stored properly, an unopened block of cheddar cheese can last for about six months in the refrigerator. Once opened, the protective barrier against external elements is compromised, reducing the cheese's shelf life to approximately 3-4 weeks before quality begins to decline. Signs that cheddar cheese has gone bad include noticeable mold, an off-putting smell, or a change to a sticky or mushy texture. It's crucial for consumers to recognize these indicators to ensure they consume the cheese while it is still within its optimal quality window and avoid potential foodborne illnesses.
