Shelf life of wheat flour at a glance
| Storage | Unopened | Opened |
|---|---|---|
| Cupboard | 1 year | 6 months |
White flour stored cool, dry and airtight often lasts months past its best-before date. Whole-wheat flour turns rancid after 4 to 6 months because of its fat content.
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.
