Hi, welcome to solsarin site, in this post we want to talk about“how long is jam good for”,

stay with us.

how long is jam good for?

Opened home-canned jams and jellies should be kept in the refrigerator at 40°F or lower. “Regular” – or pectin-added, full-sugar – cooked jams and jellies are best stored for 1 month in the refrigerator after opening. They may last longer depending on the specific product and how it is used. The expected shelf life will be shortened by keeping the container frequently open and/or out at room temperature for long periods of time during use.

At each use, you can spoon out the quantity of jam or jelly that you may require into a bowl, and replace the jar in the refrigerator quickly – this would ensure minimum exposure to sources of microbial contamination during use. Do examine the container regularly during storage for any signs of spoilage like molds, yeasts and off odors (including a fermented, “yeasty’,” or “alcohol” odor), once it is opened. Discard the entire contents of the container if these are detected.

Lower-sugar or no-sugar-added spreads may have a shorter refrigerated shelf life than those made with the traditional amounts of sugar. Natural flavor changes in the fruit base are more noticeable without the sugar to mask them; for example, some lower-sugar spreads may taste more tart or acidic over time. Light-colored spreads may also darken more quickly with less added sugar.

Freezer jams also have to be stored in the refrigerator after thawing and will only retain good quality for 3 to 4 weeks after opening. They are subject to more syneresis (“weeping” or separation of liquid from the gel) than cooked jams and jellies.

Note: For safe eating practices, store your opened jar of jam or jelly in the refrigerator until consumed, and examine it frequently for signs of spoilage (like mold or yeast growth, or off-odors, including “fermented,” “alcohol” or “yeasty” odors). Discard the product immediately if any signs of spoilage are detected.

How Long Do Jams Last?

If it’s a store-bought variety, it usually comes with a best-by date. Of course, that date is only an approximation, and a jar with an untouched seal can last in good quality for much longer.

Many companies tried the jam they stored for over 20 years and it was still perfectly fine. So while usually, the best-by date is within 12 to 24 months of the production date, you can easily assume the jam should last years more.

For unopened homemade jams, the general consensus is that you can easily store them for at least a year, if not more.

Of course, homemade jams usually don’t retain taste as well as store-bought ones, but that doesn’t mean that after 1.5 or 2 years the jam will taste bland. So as long as the seal remains intact, it should be perfectly safe (and tasty!) for at least a few years more.

Now let’s talk about opened jams. Many manufacturers generally suggest to eat their product within two weeks to a month. Of course, that’s for best quality only, and if you take good care of the jam, it should easily retain flavor for at least a few months.

When it comes to homemade jams, one month in the fridge is a pretty safe estimate of how long will the product retain flavor. Like with store-bought jams, if your storage practices and good and proper, this fruity treat will definitely keep for longer.

Please note that the periods above are for bets quality. Properly stored jam should easily last months longer.

Product Pantry ( when unopened) Refrigerator (when opened)
Low sugar jam Up to 12 months 6-9 months
Homemade jam 1-2 years Up to 1 year
Sugar-free jam Up to 9 months 6-9 months
Smucker’s fruit jam 6-9 months Up to 9 months

How Long Does Jam and Jelly Last Once Opened?

How long jam and jelly lasts depends on many things including the ingredients, how it was processed, and how it is stored, before and after the jar is opened.

Jam and jelly that has sugar as a sweetener, was made with a boiling water bath, and was stored before opening in a cool dark place should have a shelf life of at least 2 years before being opened. And, most people agree that any type of jam or jelly stays good for at least a year after opening if it has been refrigerated, if it has been kept tightly covered, and if the jar is undamaged.

But, the question is, how long does jam or jelly last after it has been opened. Most sources agree that these types of food should last at least 30 days if handled properly.

Here is a recommended chart for how long jam and jelly lasts after opening with refrigeration and without:

  • Homemade: Lasts 6 Months to 1 Year with refrigeration and 1 month without refrigeration.
  • Low Sugar: Lasts 8-9 Months with refrigeration. It is not recommended that low sugar jam and jelly be left unrefrigerated after opening as reduced sugar will not preserve sufficiently.
  • Sugar-Free: Lasts 6-9 Months with refrigeration. It should be refrigerated after opening because it does not have the preservative benefits of sugar.
  • Apple Butter: Lasts 2-3 Months with refrigeration. It should last up to 1 month after opening without refrigeration.
  • Freezer : Lasts about 1 month in the refrigerator after opening, and should not be left unrefrigerated as they normally would not go through the canning process.

How long does freezer jam last?

In its frozen state, freezer jam will last almost indefinitely (at least a year), but, like other high-water products, over time the water “crystallizes out” of the mixture. When this happens, the jam loses its smooth texture and the flavor will begin to deteriorate. Maintaining the freezer at a constant temperature is the best way to maintain frozen storage life.

When you’re ready to use it, defrost the freezer jam in the refrigerator and store it there. It will retain good quality for 3-4 weeks once defrosted. It is subject to more “weeping” (separation of liquid from the gel) than cooked jams and jellies because it hasn’t been cooked to drive off the excess liquid in the fruit. Immediately after thawing, the fruit is still firm, but after a period of time it loses its firm texture. Also, because it doesn’t usually have the high concentration of sugar that cooked jams have, which makes the water somewhat unavailable to microorganisms, it is more likely to develop mold if refrigerated for longer periods of time.

Can Jam Go Bad? How To Tell If Jam Is Bad?

Jam is fruit heated with water and sugar. As we all know, fruits don’t last forever, and neither does jam, especially after opening the jar. Let’s talk about signs of spoilage you should look for.

For an unopened container, make sure the lid isn’t popped. If it is, and you don’t know when that happened, throw it out. If you know when it (roughly) happened, and it wasn’t longer than a couple of days ago, check the jam to make sure it’s alright. Second, make sure the jar is a decent state, meaning the lid isn’t rusting or bulging. Given that everything seems to be okay, time to take a closer look at the jam.

Look for typical signs of spoilage such as mold or yeast growths, or an off smell ([LG]). If either is there, discard the jam.

When it comes to smell, it might remind you of alcohol, fermentation, or be repulsive. I once had a homemade jam that sat in the basement for several years. Once I opened it, I nearly threw up due to the smell. That’s a pretty sure sign that the jam was done for.

An important thing to note here is that light-colored jams tend to darken over time, and that’s not a sign of spoilage. They stay safe, even though the color is slightly off ([LG]).

If the preserve looks okay, smells just fine, and tastes good, chances are it’s perfectly safe to eat.

Tips to Tell If Jam Has Gone Bad

There are several ways to tell if the jam has gone bad. When it goes bad, it exhibits signs that are more or less very visible. We always advise you that whenever you see the signs we will highlight below on your jam; you should discard it with immediate effect.

Mold and yeast growth

The first sign to tell if your jam has expired is mold or yeast growth. Mold growing on jam is very visible as it has a different color from the jam. Similarly, yeast will also be pretty noticeable in a jam.

These two agents are quite harmful and could spoil the taste of your jam and cause foodborne infections. Whenever you notice that your jam has grown moldy, the best action to take would be discarding it rather than getting rid of the mold. After all, there are elements of the mold that will remain in a jam.

Change in smell

Also, if the jam has changed its smell to something fermented like yeast or alcohol, it could indicate spoilage. Fresh jam has a sweet scent that is appealing. It is important to note that a change of sealed jam in color does not necessarily denote spoilage. On many occasions, the light colored jam will assume a dark shade over time. The color change could cause alarm and leave you worrying if the jam has expired.

However, the color change is often caused by the lack of preservatives in the jam or less sugar. Besides, the color change may be accompanied by a slight change in taste. All these should not worry you as it is nature taking its course.

Organic growth

Also, organic growths on the jam could be an indication that the jam has spoiled. Consuming expired jam might be pretty harmful to your health and could cause you stomach-related complications. Whether the jam is opened or still sealed, it can go bad. However, an open jam is more prone to spoilage compared to one sealed in its original package.

The Shelf Life Of Jam

The storage life of jam is affected by the answer to the question if sugar can turn bad. Thus, some jam products are claimed to have little to no sugar. If your jam has the line “no sugar added”, then this jam will have a shorter shelf life than the ones with sugar.

Sugar is added not only to bring the sweet taste but also acts as a preservative. Some jam with less sugar will go to the dark shade in time, or it can have a tart taste than the time you first opened it. It is the normal phenomenon for the jam with less sugar or sugar-free.

Because there is no sugar mask for the fruit preserves, and there are no preservatives in it. Even if it is an unopened jam.

When jam has a darker shade than the time you bought it, check for its taste. If the taste is nearly the same or just a bit tart, jam is edible.

The Shelf Life Of Jam

The shelf life of jam also depends on its situation. An unopened jam can last for almost 2 years when kept in a cold, dry place. But an open jam should be consumed within 6 months and refrigerated since you opened it.

However, different kinds of jam will have their variety in shelf life. Homemade jam with packed sugar can last up to two years if stored properly. While jams with a lighter color have a short shelf life than those that have a dark color.

When your jam is unopened, its shelf life could last for 2 years after the printed date. To make this, you have to store it in a dark, cold place. Those are harmful sources , which will have a bad effect on the quality and the life of jam.
