What is the shelf life of mirabelle plum jam? 

Do you know the shelf life of mirabelle plum jam? If not, you’re not alone. Many people don’t necessarily know what to look for when it comes to store-bought jams and jellies and end up purchasing products that are past their expiration date.

If you’re like most people, you probably just toss a jar of jam or jelly in the fridge and assume that it’s safe to eat. But is that a safe assumption?

In this article, we will discuss the shelf life of mirabelle plum jam and provide some tips on how to determine when it’s time to retire your favorite preserved fruit.

How long does mirabelle plum jam last?

There are a few factors that can impact how long the jams will remain edible. First and foremost, the quality of the fruit will affect how long it will keep.

Additionally, the shelf life of your jam may be affected by storage conditions. Sealed jars have a higher chance of lasting longer than unsealed jars that allow air and moisture to enter. It’s always a good idea to make sure that you seal your jams securely to avoid bacteria proliferation if you want to store them for an extended period.

Let us look at unopened and opened mirabelle plum jam and how long it lasts:

Mirabelle plum jam (unopened jar) 

  • Ambient temperature: 2 years (best quality) 

The precise answer to this question depends to a large extent on the storage conditions. To maximize the shelf life of mirabelle plum jam, store it in a cool, dry place. 

Stored in good conditions, an unopened jar of mirabelle plum jam generally retains optimal quality for about 2 years at room temperature.

  • Refrigerator: 2 to 3 weeks 

Mirabelle plum jam generally keeps for 2 to 3 weeks in the refrigerator after opening the jar. To maximize the shelf life of mirabelle plum jam after opening the jar, store it in the refrigerator in an airtight container. 

Can an unopened jar of mirabelle plum jam be safely consumed after the “best before” date indicated on the jar? 

Yes, provided it is stored in good conditions and the jar is not damaged. The mirabelle plum jam jars sold on the market generally carry a date “to consume preferably before”, but it is not a date of consumption; this is the manufacturer’s estimate of how long mirabelle plum jam retains optimal quality. 

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

How do you know if mirabelle plum jam has expired? 

The best way is to smell and examine the mirabelle plum jam. If the mirabelle plum jam gives off an abnormal smell, taste, or appearance, or if mold appears, it must be discarded. 

Ideally, if you have jams or jellies that are starting to show signs of spoilage (i.e., they’re turning brown and thickened), it’s best to throw them out sooner rather than later.

If your store shelves are constantly exposed to high levels of light, the texture and flavor of the jams may start to fade over time. Additionally, certain types of bacteria can grow rapidly in warm environments and cause spoilage. So while it’s generally safe to eat jars of preserved fruit after one year has passed from their manufacture date, it’s always best to check for signs of spoilage to avoid any risks.
