Questions this answers
Tap a question for the short answer.
How long does hard cheese last?
Hard cheese really lasts 6 to 12 months when kept refrigerated, even though the label date usually says 3 to 6 months. Hard cheeses are on my keep list of foods that are still safe past the date.
How do I store hard cheese long term?
Keep hard cheese refrigerated. Stored that way its real shelf life runs 6 to 12 months, well beyond the 3 to 6 months the label suggests. Check it for slime and unwanted mold as it ages.
How do I tell if hard cheese has gone bad?
Look for unwanted mold and discoloration, smell it for sour or off odors, and feel the surface for a slimy texture. Any of those is a warning sign. Blue cheese is the exception on discoloration.
