Not recommended for uncooked dry grains

Uncooked dry grains are shelf-stable and do not require refrigeration. Cooked grains should be refrigerated promptly within 2 hours.

Freezer

6 months to 1 year (for uncooked dry grains); 1-2 months (for cooked grains)

For uncooked grains, store in airtight, freezer-safe containers or heavy-duty freezer bags to prevent freezer burn and moisture absorption. Cooked grains should be cooled quickly before freezing.

Signs of Spoilage

  • Mold growth
  • Off-odor or sour smell
  • Discoloration
  • Presence of insects or larvae (for dry grains)
  • Slimy or sticky texture (for cooked grains)

Room Temperature Safety

Cooked grains: 2-hour rule (1 hour if above 90°F/32°C)

40°F–140°F (4°C–60°C)

Cooked grains should not be left at room temperature for more than 2 hours. Discard if left out longer. Uncooked, dry grains are shelf-stable at room temperature when stored properly.
