- How long does sparkling water last once opened? The precise answer depends to a large extent on storage conditions — keep opened sparkling water refrigerated and tightly closed.
How long does sparkling water last in the refrigerator once opened? Sparkling water that has been continuously refrigerated will keep at best quality for about 2 to 3 days after opening.
Is opened sparkling water safe to drink after the "expiration" date on the bottle? Yes, provided it is properly stored and the bottle is undamaged - commercially packaged sparkling water will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the sparkling water will remain at peak quality.
How can you tell if opened sparkling water is bad or spoiled? After opening, commercially manufactured sparkling water will start to become flat; if the sparkling water develops an off odor, flavor or appearance it should be discarded.
Discard all sparkling water from cans or bottles that are leaking, rusting, bulging or severely dented.
