Taffy can stay fresh for about 6 to 12 months when stored properly in an airtight container in a cool, dry place. Exposure to air, heat, or moisture can cause it to harden or become sticky. To maintain its texture and flavor, it's best to keep it sealed and away from direct sunlight. If you notice any changes in texture or flavor, it's best to discard it.
