How long does grape jam last?

The precise answer to this question depends to a large extent on the storage conditions. Let us take a look at unopened and opened jars of grape jam to give you an idea.

Grape jam (unopened jar) 

  • Ambient temperature: 2 years (best quality) 

Stored in the right conditions, an unopened jar of grape jam typically maintains optimum quality for about 2 years at room temperature. To maximize the shelf life of grape jam, store it in a cool, dry place. 

Opened grape jam (open jar) 

  • Refrigerator: 2 to 3 weeks 

Grape jam usually keeps for 2-3 weeks in the refrigerator after opening the jar. To maximize the shelf life of grape jam after opening the jar, store it in the refrigerator in an airtight container. 

Is an unopened jar of grape jam safe to consume after the “best before” date on the jar? 

Yes, provided it is stored in good conditions and the jar is not damaged. Commercial jars of grape jam usually bear a “best before” date, but this is not a best-before date; this is the manufacturer’s estimate of how long the grape jam will retain optimum quality. 

After this date, the texture, color, or flavor of grape jam may change, but in most cases, it will still be safe to eat if stored in the correct conditions, if the jar is not damaged and if it shows no signs of tampering. 

How do you know if grape jam has expired? 

The best way is to smell and examine the grape jam. If the grape jam smells, tastes, or looks abnormal, or if mold appears, it should be discarded. 

Grape jam storage tips

  • Store grape jam in an airtight container in a cool, dry place
  • You can also keep the grape jam in an airtight container in the refrigerator where it will last longer.
  • Do not leave opened grape jam on the counter or in direct sunlight
  • Opened grape jam should be stored in the fridge at all times to preserve its quality.

When it comes to the shelf life of grape jam, it is safe to say that this does not have a set time frame. The two-year shelf life for this product indicates that the quality of ingredients used and storage conditions should be kept high.

In case you buy a jar and notice issues with its freshness, don’t hesitate in calling your supplier. Also, keep an eye out for signs of fermentation such as a musty smell or changes in color. As far as the taste goes, you can only tell whether it is fresh or preserved by tasting it at home!
