Can you eat sharp cheddar cheese a year after sell buy date?

Sharp cheddar cheese can often be safe to eat a year after the sell-by date if it has been stored properly. Hard cheeses like cheddar have a lower moisture content, which helps inhibit bacterial growth. However, always check for signs of spoilage, such as mold, off smells, or unusual texture, before consuming. If in doubt, it's best to err on the side of caution and discard it.
