When do grains expire?

Grains can have varying shelf lives depending on their type and storage conditions. Generally, whole grains can last 6 months to a year if stored in a cool, dark place, while refined grains may last 1 to 2 years. It's essential to check for signs of spoilage, such as off odors or insect infestations, and to store grains in airtight containers to extend their freshness. Always refer to packaging for specific expiration or best-by dates.
