Answer: 8 months
White flour, stored in an air tight container in a cool, dry place (not above the stove or under the sink) will retain its quality for up to eight months, according to Fadi Aramouni, Ph.D., a professor of food science at Kansas State University. If you want to extend its shelf life, store it in the refrigerator for up to two years or indefinitely in the freezer. Whole wheat flour contains the oils from the germ of wheat kernel so it can turn rancid when stored at room temperature. Rather, store it in the refrigerator for up to six months or in the freezer for up to a year for the best quality.
