Tips
  • How long does boysenberry jam last once opened? The precise answer depends to a large extent on storage conditions — to maximize the shelf life of opened boysenberry jam, keep it refrigerated and tightly covered.
  • How long does opened boysenberry jam last in the refrigerator? Boysenberry jam that has been continuously refrigerated will generally stay at best quality for about 1 year.
  • Is opened boysenberry 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 boysenberry 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 boysenberry jam will remain at peak quality.
  • The storage time shown for opened boysenberry 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 boysenberry jam is bad or spoiled? The best way is to smell and look at the boysenberry jam: if the jam develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
