How long will cranberry sauce last in refrigerator?

Homemade cranberry sauce can last in the refrigerator for about 1 to 2 weeks when stored in an airtight container. Store-bought cranberry sauce, if unopened, can last until its expiration date, but once opened, it should also be consumed within 1 to 2 weeks. Always check for any signs of spoilage, such as off smells or mold, before consuming.
