An unopened bottle of pomegranate juice lasts until the expiration date printed on the label, as long as it stays refrigerated. Once you open it, you have about two weeks to finish it. Those timelines shift depending on how you store it and whether the juice has been pasteurized.
Unopened Pomegranate Juice
Most commercially sold pomegranate juice, like POM Wonderful, is pasteurized and sold refrigerated. Keep it in the fridge from the moment you bring it home, and it will stay good through the printed expiration date. POM Wonderful specifically states their juices should be refrigerated at all times to preserve taste and antioxidant content. Leaving a bottle on the counter, even for a few hours, shortens its usable life because warmth accelerates bacterial growth and degrades the juice’s flavor.
If you buy shelf-stable pomegranate juice (the kind sold in unrefrigerated cartons or bottles), it typically lasts several months in your pantry. Once you open it, treat it like the refrigerated version: move it to the fridge and use it within two weeks.
After Opening: The Two-Week Window
POM Wonderful recommends consuming their juice within two weeks of opening or by the expiration date, whichever comes first. That two-week guideline is a good rule of thumb for any pasteurized pomegranate juice. Every time you open the bottle, you introduce air and trace amounts of bacteria from your hands and the environment. Refrigeration slows that bacterial growth but doesn’t stop it entirely.
To get the most out of that window, reseal the bottle tightly after every pour and return it to the fridge immediately. Storing it toward the back of the refrigerator, where temperatures are more consistent, helps more than keeping it in the door where it’s exposed to warm air every time you open the fridge.
Unpasteurized Juice Has a Shorter Life
Fresh-pressed pomegranate juice from a farmers’ market, juice bar, or made at home hasn’t been heat-treated to kill bacteria. The FDA requires unpasteurized juices to carry a warning label noting they may contain harmful bacteria that can cause serious illness, particularly in children, older adults, and people with weakened immune systems. This type of juice should be consumed within a few days of pressing, kept refrigerated the entire time, and never left at room temperature.
Freezing for Longer Storage
Freezing is the best way to extend pomegranate juice well beyond that two-week window. According to the UC Master Food Preserver Program, pomegranate juice freezes well in freezer-safe containers. The key detail: leave at least half an inch of space at the top of the container, because the liquid expands as it freezes. Skip this step and you risk a cracked container and a sticky mess in your freezer.
Frozen pomegranate juice holds its quality for about 8 to 12 months. It remains safe indefinitely at 0°F, but flavor and nutritional value gradually decline after that first year. Thaw it in the refrigerator overnight rather than on the counter. Once thawed, use it within a few days and don’t refreeze it.
Ice cube trays work well if you only need small amounts for smoothies or cooking. Freeze the juice in trays, pop the cubes out, and transfer them to a freezer bag. This way you can pull out exactly what you need without thawing an entire container.
How to Tell It’s Gone Bad
Pomegranate juice that has turned will usually tell you through smell first. Fresh pomegranate juice has a tart, slightly sweet aroma. Spoiled juice develops a sharp, acrid, or vinegar-like smell, which signals fermentation. If it smells like alcohol or nail polish remover, bacteria or yeast have been at work and the juice should be discarded.
Visual changes are the next clue. Look for:
- Color shift: Fresh pomegranate juice is a deep ruby red. Browning or significant darkening suggests oxidation and age.
- Mold: Any visible mold on the surface or around the cap means the entire bottle should go. Don’t try to scoop off mold and drink the rest.
- Fizzing or bloating: A swollen bottle cap or bubbles when you open it indicate active fermentation. This juice is no longer safe.
Taste is your last line of defense. Pomegranate juice that has gone off tastes noticeably bitter or sour in a way that’s different from its normal tartness. If anything seems off, trust your instincts and toss it. A bottle of juice isn’t worth a bout of food poisoning.
Quick Reference by Storage Method
