Tips
  • How long does a bottle of mustard last once opened? The precise answer depends to a large extent on storage conditions — store opened mustard in a cool, dark place and keep tightly covered at all times.
  • How long does an opened bottle of mustard last at normal room temperature? Opened mustard will usually keep for 1 to 2 months when stored in the pantry.
  • To extend the shelf life of opened mustard, refrigerate it.
  • How long does mustard last after the “Use By” or “Best By” date? An opened bottle of mustard that has been continuously refrigerated will usually remain at best quality for 1 year after the "Use By" or “Best By” date on the package.
  • Is opened mustard still safe to use after the expiration date? Yes — while the mustard's texture, color or flavor may change, in most cases, an opened bottle of mustard will still be safe to consume after the “Best By," "Best if Used By," and "Use By" dates have passed, provided it has been kept continuously refrigerated and tightly covered.
  • How can you tell if mustard has gone bad? If mustard develops an off odor, flavor or appearance, it should be discarded for quality purposes; if mold appears, discard the entire product.
