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.
