How Long Can I Keep Fish Sauce In The Refrigerator?

This isn’t to claim that fish sauce is always good, whether it’s before or beyond the expiration date (though you should always refrigerate it after opening). Its quality might decline with time as a result of chemical interactions, resulting in color changes or the development of “off” flavors. Mold or yeast may form on the interior surface or lip of the bottle when there is extra moisture and less salt on rare instances. These growths are mostly harmless, but as with any meal, if it looks, smells, or tastes unusual, it should be discarded.

How long can you use fish sauce after opening?

  • What is the shelf life of fish sauce? The exact answer is very dependent on storage conditions; to extend the shelf life of fish sauce, keep it in a cool, dark cabinet away from direct heat and sunshine.
  • At room temperature, how long does unopened or opened fish sauce last? Fish sauce, whether unopened or opened, will normally keep for 3 to 4 years at room temperature if properly maintained.
  • When not in use, keep the container tightly closed to extend the shelf life of the fish sauce.
  • Is it okay to use fish sauce after the “expiration” date printed on the package? Yes, as long as it’s stored properly and the package isn’t damaged. Commercially packaged fish sauce will usually have a “Best By,” “Best if Used By,” “Best Before,” or “Best When Used By” date, but this isn’t a safety date; rather, it’s the manufacturer’s estimate of how long the fish sauce will stay at peak quality.
  • How can you know if your fish sauce is still edible? Fish sauce loses its flavor with time and should be thrown if it acquires an off odor, flavor, or look.
