What is the shelf life of grape juice?

Unopened grape juice typically has a shelf life of 12 to 18 months when stored in a cool, dry place. After opening, it should be consumed within 7-10 days when refrigerated. To extend the shelf life of opened grape juice, you can freeze it in airtight containers for up to 6 months. Be sure to leave some headspace in the container to allow for expansion during freezing. When ready to use, thaw the frozen grape juice in the refrigerator overnight.
