Tips

  • How long does oyster sauce last once opened? The precise answer depends to a large extent on storage conditions - to maximize the shelf life of opened oyster sauce, refrigerate and keep tightly covered at all times.
  • How long does opened oyster sauce last in the refrigerator? Oyster sauce that has been continuously refrigerated will generally stay at best quality for about 2 years.
  • Is opened oyster sauce safe to use after the "expiration date"? Yes, provided it has been stored properly, the bottle is undamaged, and there are no signs of spoilage (see below) - commercially bottled oyster sauce 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 oyster sauce will remain at peak quality.
  • The storage time shown for opened oyster sauce is for best quality only - after that, the oyster sauce's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been kept continuously refrigerated, the bottle is undamaged, and there are no signs of spoilage (see below).
  • How can you tell if opened oyster sauce is bad or spoiled? The best way is to smell and look at the oyster sauce: if the oyster sauce develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
