Expiration & Storage Tips
When does unbleached flour expire?
Unopened, unbleached flour can last for up to a year if stored in a cool, dry place. Once opened, it should be used within six to eight months for optimal freshness and quality. However, the actual expiration could vary based on storage conditions. For instance, if stored in an airtight container in the fridge, it can last up to two years, or even longer if frozen.
How do you tell if unbleached flour is bad?
One clear sign that your unbleached flour has gone bad is an off smell - a kind of musty or sour odor. Exposure to moisture can encourage mold growth which will have a notable smell. Additionally, you might see discolored spots, which is another clue of mold. Finally, if you notice bugs or their droppings, that's a sure sign the flour should not be used.
