How long does flour last? Fridge, freezer & pantry

Flour storage guide — how long it lasts
Unopened, flour keeps in the pantry for around 1 year. Once opened, use it within about 6 months for best quality and safety.

Storage temperatures: keep the fridge at ≤4 °C (40 °F), the freezer at −18 °C (0 °F), and the pantry cool and dry at room temperature.

Times are for unopened, properly stored flour and reflect best quality. Always use your senses and follow any date on the package.

Signs flour has gone bad

  • A musty or rancid, crayon-like smell.
  • Clumping, webbing, or any sign of pantry pests.
  • Mould or damp patches inside the bag.

When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.

Best way to store flour

Flour is the ultimate multiplier — one cheap bag is the base for bread, tortillas, pancakes, pizza dough, dumplings, and a gravy thickener, replacing pricier pasta and boxed mixes. Keep it airtight in a cool, dark, dry pantry; refined white flour lasts many months there.

How long does flour last in the fridge or refrigerator?

Flour is usually stored at room temperature rather than the fridge — about 1 year in the pantry. Check the table above for the full breakdown.
