How long is opened flour good?

Opened flour can generally be stored for about 6 to 12 months if kept in a cool, dry place, away from moisture and contaminants. For optimal freshness, it's best to store it in an airtight container. Whole wheat and other specialty flours may have a shorter shelf life, typically around 3 to 6 months. Always check for any off smells or signs of spoilage before use.
