How long does cheese last in the fridge?
Cheese is the one shelf in the fridge with three different answers. CSIRO’s refrigerated-storage guide gives hard cheese such as cheddar one to three months, soft cheeses such as brie and camembert two to three weeks, and cottage, ricotta and cream cheese ten days. This site takes the short end of each and says so: one month for the block, two weeks for the wedge, ten days for the tub.
Three cheeses, three clocks
The gap between a block of tasty and a tub of ricotta is not a rounding difference. It is the difference between a month and a week and a half, and it comes down to moisture. Hard cheese has had most of its water pressed out, which is why CSIRO can give it a month at the cautious end. Soft, ripened cheese still carries plenty. The fresh cheeses — cottage, ricotta, cream cheese — are mostly water held in curd, which is why their ten days sits closer to milk’s window than to cheddar’s.
Haloumi sits on the same two-to-three-week line as brie in our shelf-life reference, the site’s reading of CSIRO’s soft-cheese row. Feta is not a row on CSIRO’s table at all. Where the table is silent, this site gives no number, and the date on the packet is the rule.
How long does cheese last once opened?
The same as before it was opened, counted from the day it came home. CSIRO’s figures do not distinguish a cut block from a sealed one, so opening the wrapper does not reset the clock and does not shorten it either. A block of cheddar opened in week two still has the two weeks that were left.
What opening changes is exposure. A cut face dries out, picks up fridge smells and grows mould faster than a sealed one, so wrap it tightly or move it to a container. And where the packet carries a use-by date that lands earlier than CSIRO’s window, the use-by date wins. A best-before date is a quality estimate, and cheese kept cold is one of the foods that most often outlives its own label.
Signs to trust
Mould on soft or fresh cheese means it is done, wherever it appears. A wedge of brie that smells sharply of ammonia is done. Ricotta or cottage cheese with a sour smell, a yellow tinge or liquid pooling on top is done. A hard block is the one case that needs judgement rather than a rule, and this site does not hand out a rule it cannot source: if the block smells wrong, treat it the way you would treat the brie.
Why cheese still ends up in the bin
A month sounds like too much time to waste a block of cheddar in, and it is. Cheese gets binned anyway, for one reason. It is bought for a purpose — a lasagne, guests on Saturday, a school lunchbox — the purpose passes, and the rest slides to the back of the shelf behind the milk with no date on it that anyone remembers. Three cheeses in one fridge, each on a different clock, and none of the clocks visible.
That is the failure Pantry is built to take out of the fridge. Scan the receipt and each cheese is dated the day it came home with its own window: the block on the longest clock, the wedge on a two-week one, the tub on ten days — three windows off one docket, not one generic countdown stamped across the shelf. The morning digest names the brie in its second week and leaves the cheddar alone, because the cheddar is fine. And every phone in the household sees the same dates on the same three cheeses, so the wedge bought for Saturday’s guests becomes somebody’s Tuesday dinner, not next month’s bin.
