Greetings. The guidelines for best quality flour storage are to keep in an airtight container for 6 to 12 months. Whole wheat flour should be kept refrigerated or frozen in an airtight container for 6 to 8 months. Specialty flours should be kept in an airtight container for 6 to 8 months. Humidity over 60% can cause flour to clump and spoil. Food-grade metal, glass or plastic containers with tight fitting lids are the best options. Optimum storage temperature is 50 to 70 degrees F. Flour stored in the pantry or kitchen cupboards should be inspected for pests every two months. For more information on recommended storage times of foods, see Food Storage for Safety and Quality.
