Shelf Life Tips

  • How long does beer last once opened? The precise answer depends to a large extent on storage conditions — to maximize the shelf life of opened beer, keep it refrigerated and tightly covered.
  • How long does opened beer last in the refrigerator? Beer that has been continuously refrigerated will generally stay at best quality for about 1 day.
  • Is opened beer safe to drink after the "expiration" date on the package? Yes, provided it is properly stored and the package is undamaged - commercially packaged beer 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 beer will remain at peak quality.
  • How to tell if opened beer is bad? If beer develops an off odor, flavor or appearance, it should be discarded for quality purposes.
