Best Before Date: Can Flour Actually Spoil?

In principle, flour can be kept almost indefinitely because it is dry and germs can hardly multiply in it. The best-before date printed on the packaging is a manufacturer’s guarantee: the product will last at least up to this date if it is stored properly. However, that doesn’t mean it has to spoil immediately after the date has passed.

Basically, the drier a product is, the slower it spoils. However, whole wheat flour still contains some natural fat that can go rancid. It, therefore, does not keep as long as white flour, which you store in a cool, dry, airtight place and away from pests. However, if not stored properly, it can become infested with food moths and other vermin, or take on a musty, inedible smell and taste.
