How Long Does Cheese Last?
By James OkaforReviewed 2026-01-01
Hard cheese keeps 3–4 weeks after opening in the fridge; soft cheese 1–2 weeks. Grated hard cheese freezes for 6 months. Trim mold off hard cheese (1 inch around the spot), but throw out any moldy soft cheese. Wrap in paper, not tight plastic.
Cheese is the rare dairy product that gets better with a little attention. Stored badly, it dries out, sweats, and turns bitter. Stored well — in paper, in the right drawer — a block of hard cheese stays delicious for weeks.
The rule that explains everything: cheese is alive. It needs to breathe but not dry out. Tight plastic wrap suffocates it and traps the moisture that breeds mold; leaving it bare dries it into a crumbly shell. Paper wrap with a loose plastic covering is the sweet spot.
How long cheese lasts
| Storage method | Duration | Best practice |
|---|---|---|
| Fridge — hard cheese (opened) | 3–4 weeks | Rewrap in fresh paper after each use |
| Fridge — semi-soft (mozzarella) | About 2 weeks | Keep in brine or fresh paper |
| Fridge — soft cheese (brie, feta, cream cheese) | 1–2 weeks | Throw out if mold appears |
| Fridge — unopened hard cheese | 2–6 months | Store in the original packaging |
| Freezer — grated hard cheese | Up to 6 months | Grate before freezing; thaw in fridge |
| Room temperature | 2 hours max for service | Return to fridge promptly |
Storage conditions for cheese
Cheese belongs in the warmest part of the fridge — usually the vegetable or cheese drawer — not the door. The door's temperature swings cause condensation, and condensation is mold fuel.
Wrap cheese in waxed or parchment paper first, then tuck it loosely in a plastic bag or container so it can still breathe. Rewrap in fresh paper after every use: old paper holds the moisture that makes cheese sweat. For grated and sliced cheese, the fridge-life is shorter — moisture and surface area mean faster spoilage — so buy those in small amounts.
Storage tip
Grate a large block of cheddar or Parmesan and freeze the grated cheese in a zip-top bag. It thaws in minutes, cooks identically, and gives you hard-cheese convenience at block-cheese prices. ::
Mold: when to cut and when to throw
Hard and semi-hard cheese — cheddar, Parmesan, Swiss, Gouda — is dense enough that mold cannot penetrate. Cut off at least 1 inch around and below the mold spot, rewrap the rest, and it is safe to eat.
Soft and shredded cheese is the opposite. Brie, feta, ricotta, cream cheese, and pre-shredded blends are moist enough that mold spores run through the whole piece. Any visible mold means the entire package goes in the bin.
Warning
Never just scrape mold off soft cheese and eat the rest. In soft, high-moisture cheeses, mold roots below the visible surface where you cannot see it. When in doubt on any soft cheese, discard. ::
Does cheese freeze well?
Hard cheese freezes well and soft cheese does not. Grated hard cheese freezes for up to 6 months and thaws in minutes — ideal for casseroles, sauces, and pizza. Freezing whole blocks is fine for cooking too, though the texture turns crumbly, so skip it for cheese boards. Freeze cheese at 0°F, wrapped tightly to prevent freezer burn, and thaw in the fridge overnight.
For the temperature rules behind all of these times, see the food safety temperature guide and the refrigerator storage guide.
Frequently asked questions
How long does cheese last in the fridge?
Hard cheeses like cheddar and Parmesan keep 3–4 weeks after opening; semi-soft cheeses like mozzarella about 2 weeks; soft cheeses like brie, feta, and cream cheese 1–2 weeks. Unopened hard cheese lasts months. The fridge must stay at 40°F or below, and cheese should be re-wrapped in fresh paper after each use.
Can you freeze cheese?
Hard and semi-hard cheese freezes well for up to 6 months if grated first — grated cheese thaws in minutes and is perfect for cooking. Freezing changes the texture of cheese (it becomes slightly crumbly), so frozen cheese is better for cooking than for serving on a board. Soft cheese does not freeze well.
Is cheese with a little mold safe to eat?
For hard cheeses — cheddar, Parmesan, Swiss — cut off at least 1 inch around and below the mold spot and the rest is safe to eat. For soft cheeses like brie, feta, cream cheese, and shredded cheese, mold means throw it out: moisture lets mold penetrate the whole piece. Never eat moldy soft cheese.
What is the best way to store cheese?
Wrap cheese in waxed or parchment paper, then loosely in plastic or a container. This lets the cheese breathe without drying out, and it prevents condensation that breeds mold. Avoid tight plastic wrap alone, which suffocates cheese and traps moisture. Rewrap in fresh paper after every use.
Why does my cheese get slimy?
Slimy, sticky cheese is usually moisture trapped against the surface — from tight plastic wrap or a too-humid cheese drawer. Pat it dry and rewrap it in paper. If the slime is on a soft or shredded cheese, throw it out. Sliminess with a sour or ammonia smell means spoilage, not just condensation.
