How Long Does Jam & Jelly Last?
Opened jam or jelly lasts about 6 months in the fridge. Unopened jars keep 1 year in the pantry. Low-sugar and freezer jams last only 3–4 weeks refrigerated once opened or thawed.
Jam & Jelly — opened
shelf life- Unopened: 1 year in the fridge
- Homemade: 3–4 weeks in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Jam, jelly, preserves and marmalade are fruit or fruit juice cooked with sugar and pectin until they set. A high sugar level and the fruit's acidity bind up water and keep bacteria out, so sealed jars last a year or more. After opening, mold is the main threat, especially in low-sugar and no-sugar-added spreads.
How to store jam & jelly
- Refrigerate jam after opening and spoon it out with a clean utensil, not the knife that just spread butter or peanut butter.
- Keep toast crumbs out of the jar. Crumbs and butter smears are where mold most often takes hold.
- Use low-sugar, reduced-sugar and fruit-only spreads within 3–4 weeks of opening, since they have far less sugar to protect them.
- Store home-canned jam in a cool, dark, dry place, remove the screw bands, and check that every lid is still concave before opening.
- Keep freezer jam frozen until you need it, thaw it in the fridge, and finish it within 3–4 weeks.
How to tell if jam & jelly has gone bad
- Any mold, whether white, green or blue fuzz, on the surface, under the lid or on the jar walls.
- A fermented, yeasty or wine-like smell, sometimes with small bubbles in the jam.
- An unopened jar with a domed or unsealed lid, or one that spurts or hisses when opened.
- Color darkened to brown with a stale, flat flavor, which is a loss of quality in an old jar.
- Liquid weeping from the gel is normal; stir it back in unless other signs are present.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Frequently asked questions
Does jam need to be refrigerated after opening?
Yes. Once opened, jam and jelly should be kept in the fridge, where they last about 6 months. Sugar slows spoilage but does not stop mold, and airborne mold spores land on the surface each time the jar is opened. Unopened jars are shelf-stable in the pantry for about 1 year.
Can I scoop the mold off jam and eat the rest?
No. The USDA advises discarding jams and jellies that have mold on them. Some molds produce mycotoxins, and in a soft spread they can extend below the visible growth, so scooping off the top is not a reliable fix. Throw out the jar and use clean utensils with the next one.
How long does homemade jam last?
Home-canned jam processed in a boiling water bath and sealed keeps about 1 year in a cool, dark pantry, then 1–6 months in the fridge once opened depending on its sugar content. Freezer jam and other unprocessed jams last 3–4 weeks in the fridge or up to 1 year frozen.
Is jam still good after the expiration date?
Unopened commercial jam is generally good for 6–12 months past its best-by date if the lid is sealed and flat, since the date is about quality. It may be darker and less fruity. After opening, judge by time in the fridge and by inspection, and discard it at the first sign of mold or fermentation.
