Apple cider storage requirements vary by pasteurization

The storage requirements for apple cider depend significantly on whether the product is fresh, unpasteurized, or shelf-stable. Fresh, unpasteurized cider from orchards carries a higher risk of containing harmful bacteria and must be kept refrigerated at 40°F or below, similar to milk. Experts from Iowa State University and the University of Maine Extension emphasize that untreated juice requires constant refrigeration to maintain safety.

In contrast, shelf-stable or pasteurized cider that has undergone safety treatments can be stored in a cool, dry pantry until it is opened. Once any type of cider is opened, it must be refrigerated and used within a few days. Consumers are advised to check labels or consult sellers to distinguish between perishable orchard products and treated, shelf-stable versions.
