Shelf life of rapeseed oil at a glance
| Storage | Unopened | Opened |
|---|---|---|
| Cupboard | 12 months | 3 months |
| Fridge | – | 4 months |
Store cool, dark and tightly closed; refined oil does not need the fridge. Cold-pressed rapeseed oil is more delicate and turns rancid sooner once opened.
Past its date does not mean spoiled
These are guide values for food stored correctly. A best-before date is not a throw-away date: many products are still fine after it. Check how it looks, smells and tastes. Mould, an unusual smell or a bulging can are reasons to throw it away. A use-by date is different: do not eat the food after it.
