How long does hard cheese last in the fridge?
A block of hard cheese keeps 6 months unopened in the fridge and 3–4 weeks once opened — and surface mold on a hard block can be cut away, an inch around and below the spot.

Can it sit out?
Hard cheese is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if hard cheese has gone bad
- An ammonia or sour smell inside the wrap
- A slimy or greasy film on the surface
- Mold running through the body of the block, not just sitting on the surface
When in doubt, throw it out.
Rewrap the block in fresh paper or loose plastic after each use — a sweating block molds faster.
