Flour does go bad over time through staleness, flavor loss, rancidity, or pest infestation, with shelf life varying by type—refined flour lasts 12-18 months while whole grain and nut flours last only 3-6 months. Proper storage in airtight containers in cool, dry conditions, or in the refrigerator or freezer for more perishable varieties, can extend freshness and preserve flavor.
