Shelf Life Tips

  • How long does an unopened bottle of katsu sauce last? The precise answer depends to a large extent on storage conditions - to maximize the shelf life of katsu sauce, store in a cool, dry area.
  • How long does an unopened bottle of katsu sauce last at room temperature? Properly stored, an unopened bottle of katsu sauce will generally stay at best quality for about 3 years, although it will usually remain safe to use after that.
  • Is unopened katsu sauce safe to use after the "expiration date" on the bottle? Yes, provided it is properly stored and the bottle is undamaged - commercially packaged katsu 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 katsu sauce will remain at peak quality.
  • Storage time shown is for best quality only - after that, the katsu sauce's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been stored properly, the bottle is undamaged, and there are no signs of spoilage (see below).
  • How can you tell if katsu sauce is bad or spoiled? The best way is to smell and look at the katsu sauce: if the katsu sauce develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
