If you want to extend the shelf life of your homemade jam, you can process it in a hot water bath canning. We do this for our low-sugar jams like blackberries and blueberries and anything with rhubarb in it. It takes a little longer, but when someone asks me, how long does homemade jam last, I can tell them that this will make the jam last for at least 18 months when stored in a cool, dry place. Check to make sure each jar is sealed by testing the lids.
Sugar has an important part to play in food preservation methods and in answering the question, how long does homemade jam last. When used in making homemade jam, sugar not only adds a little bit of sweetness to otherwise tart fruit but also acts as a preservative. When you make homemade jam with sugar, the sugar helps to thicken the jam by drawing the water out of the fruit during the cooking process.
After the jam is finished cooking, the sugar acts as a barrier against any harmful bacteria that may want to grow. You can most definitely use other sweeteners as alternatives to sugar when making homemade jam, or you can leave it out altogether and use unsweetened pectin for thickening your jam. For homemade jams made using sugar and processed by canning in a hot water bath, you can expect to get about two years of shelf life when stored in a cool, dry place.
Homemade jams made without sugar and processed by canning in a hot water bath will last about half that long — about one year — when stored in cool, dry place out of direct sunlight. Some fruits may darken more quickly with less sugar present. Flavor changes that occur over time become more evident if they are usually otherwise masked by the sugar.
It is always a good practice to carefully examine all home-canned jars of food for signs of spoilage prior to opening and eating. If there is any mold on a jar of jam or jelly, or signs of other spoilage, discard the entire contents of the jar or container. They may last longer depending on the specific product and how it is used. How long does jam last? That depends. How long does bread last? In general, jam lasts only as long as the quickest expiring ingredient it is mixed with.

What are our shelf life resources? From The Blog. While they taste nothing alike, the reason is that all of them contain quite a lot of natural preservatives.
In the case of jams, that preservative is sugar. You should store an unopened jar in a cool and dark place, away from sunlight and sources of heat. Exposure to light and heat could degrade the jam quickly, which may affect its flavor, consistency, and appearance. The pantry or a cabinet in the kitchen are the best choices.
Remember to always seal the jar tightly and put it back into refrigeration after scooping as much as you need. This ensures the jam retains good quality for the longest and minimizes the chance of microbial contamination that might make it spoil. The modus operandi for both store-bought and homemade jams is the same here as well.
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.
