Shelf Life Tips
- How long does unopened sparkling water last? The precise answer to the question depends to a large extent on storage conditions - store unopened bottles of sparkling water in a cool, dark area.
To extend the shelf life of unopened sparkling water, keep unopened sparkling water away from direct sources of heat or light.
How long does unopened sparkling water last at room temperature? Properly stored, unopened sparkling water will generally stay at best quality for about 12-18 months when stored at room temperature, although it will usually remain safe to drink after that.
Is unopened 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 unopened sparkling water will remain at peak quality.
Storage times shown are for best quality only - after that, the unopened sparkling water's color or taste may change, but in most cases, it will still be safe to consume if it has been stored properly and the bottle is not damaged.
How to tell if sparkling water is bad? If sparkling water develops an off odor, flavor or appearance, it should be discarded.
