How long does Cheddar last?
In the fridge: 21 days
In the freezer: 180 days
Cheddar lasts 3–6 weeks in the fridge once opened, longer than most cheeses thanks to its low moisture and high salt. Sealed blocks keep 6+ months past the printed date in many cases. The harder and more aged the cheddar, the longer it lasts. A small bit of mold can be cut away with a 1cm margin — the rest is safe. Freezing for grating works well; texture suffers for slicing.
How to store it
- Wax paper + loose plastic
- Cheese drawer (4–8°C)
- Cut as needed, don't pre-slice
- Replace wrapping every few uses
- Bring to room temp 30–60 min before serving
Signs it has gone bad
- Spreading mold beyond cuttable margin
- Ammonia or sharply sour smell
- Slimy surface
- Bitter taste

How long does cheddar last in the fridge?
Opened cheddar lasts 3–6 weeks in the fridge. Sealed blocks last 6+ months.
Can you cut mold off cheddar?
Yes — cut away with a 1cm margin. Hard cheeses like cheddar resist mold spread better than soft cheeses.
Can you freeze cheddar?
Yes — grated freezes best (3–6 months). Sliced or block cheddar gets crumbly after thawing, fine for melting.
