How Long Does Cranberry Juice Last in the Refrigerator?
How to store and identify fresh cranberry juice
Cranberry juice lasts 7–10 days in the refrigerator after opening.
Once you break the seal on a bottle of cranberry juice, refrigeration is essential to maintain its tart flavor and prevent spoilage. While unopened juices are shelf-stable until their expiration date, an opened container needs consistent cold temperatures to slow down oxidation and microbial growth. To ensure your juice remains safe to drink, keep the cap tightly sealed and avoid leaving the bottle at room temperature for long periods. Monitor the liquid for changes in clarity, unusual bubbles, or off-putting odors. If you notice any signs of fermentation or mold, discard the liquid immediately rather than attempting to taste it.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
