Pantry storage

Does flour need to be refrigerated?

No. A sealed bag keeps 6 to 12 months in the pantry, and an open bag can stay there too. FoodKeeper says opened white flour can stay in the pantry, and the fridge roughly doubles its time.

These times are a guide, not a safety guarantee, and a label that says to refrigerate comes first.

Unopened and opened

Unopened and opened packages keep for different times. These are the times the source gives.

After opening

Where to keep it once open
Pantry or cupboard. The fridge is optional, but the quality lasts longer there.

Sources and limits

The after-opening time runs from the day you opened it, not from the date printed on the package, so write that day down. Well Stockd doesn’t know when your package was made, bought or opened: follow the package directions, keep it somewhere cool and dark, and check the official listing when food safety is in question.

The storage times above are quoted from the sources below. They’re a guide, not a safety guarantee: quality varies with packaging, temperature and how the package is handled between uses. Nothing here overrides a label that says to refrigerate. This page was last updated .
