How long does jelly last in fridge?
In general you can probably expect your homemade jelly to last for around 6 to 12 months if you put it in the fridge, though again it’s got about a month of shelf life if you leave it out in the open.
How can you tell if jelly is spoiled?
Typical signs of jam spoilage include mold or yeast growth, or any off odor. If the jam smells like yeast, alcohol, or anything fermented, get rid of it. Same thing if there are any organic growths on the surface. If everything looks and smells okay, feel free to give it a taste.
