The short answer
All-Purpose Flour lasts as long as you store it correctly — which can mean anywhere from a few days on the counter to a year in the freezer. The numbers above represent best quality per USDA and FDA guidelines, not absolute safety limits.
Why these numbers vary
Wheat flour for baking. Storage life depends on temperature consistency, humidity, packaging, and how fresh it was when you got it. Refrigerators that swing between 38°F and 45°F shave days off these numbers; vacuum-sealing or freezing extends them.
How to tell if all-purpose flour is bad
- Rancid musty smell
- Bug infestation (weevils)
- Yellowing
- Clumping
Storage tips
- Whole grain flour goes rancid faster than white
- Freezer for whole wheat
- Bay leaf in container deters bugs
