Tips
  • How long does plum jam last once opened? The precise answer depends to a large extent on storage conditions — to maximize the shelf life of opened plum jam, keep it refrigerated and tightly covered.
  • How long does opened plum jam last in the refrigerator? Plum jam that has been continuously refrigerated will generally stay at best quality for about 1 year.
  • Is opened plum jam safe to use after the “expiration” date on the jar? Yes, provided it has been stored properly, the jar is undamaged, and there are no signs of spoilage (see below) — commercially jarred plum jam 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 plum jam will remain at peak quality.
  • The storage time shown for opened plum jam is for best quality only — after that, the jam'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 jar is undamaged, and there are no signs of spoilage (see below).
  • How can you tell if opened plum jam is bad or spoiled? The best way is to smell and look at the plum jam: if the jam develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
