Common questions
How long does white flour last in the fridge?
1 year in a fridge running at 0–5°C (USDA FoodKeeper guidance). After that, quality and safety both start to slip, and because the bacteria that cause food poisoning are invisible, ‘it seems fine’ is not a reliable test. When in doubt, throw it out.
How can I tell if white flour has gone off?
Rancid or stale smells, clumping, insects, mould and bulging, leaking or rusted tins are all reasons to throw it away. Do not rely on this alone: the time guideline matters even when everything looks fine.
Can I freeze white flour to keep it longer?
Freezing is not recommended for this food; the texture tends to suffer badly. Buy or cook only what you will use in time.
Can I keep white flour out of the fridge?
Yes, for a short time only: around 6–12 months in the cupboard or at room temperature.
