How long will flour and cornmeal last in storage?

Flour can last up to a year when stored in a cool, dark place in an airtight container, while whole wheat flour typically lasts about 3 to 6 months due to its higher oil content. Cornmeal can last around 6 to 12 months when stored similarly, but its shelf life is shorter for whole grain varieties. For both, freezing can extend their shelf life significantly. Always check for signs of spoilage, such as off odors or discoloration, before use.
