Shelf Life Tips

  • How long does bottled water last once opened? The precise answer depends to a large extent on storage conditions — keep opened bottled water refrigerated and tightly closed.
  • How long does bottled water last in the refrigerator once opened? Bottled water that has been continuously refrigerated will keep at best quality for about 4 to 6 days after opening.
  • Is opened bottled water safe to drink after the "expiration" date on the bottle? Yes, provided it is properly stored and the bottle is undamaged - commercially packaged bottled 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 bottled water will remain at peak quality.
  • How can you tell if opened bottled water is bad or spoiled? If the bottled water develops an off odor, flavor or appearance it should be discarded.
