How long can Swans Down flour last?

Swans Down flour, like other cake flours, can last for about 6 to 12 months when stored properly in a cool, dry place in an airtight container. If stored in the refrigerator or freezer, it can last even longer, up to 1 to 2 years. Always check for any off smells or discoloration before use, as these can indicate spoilage.
