Expiration & Storage Tips
When does preserves expire?
Preserves, whether homemade or store-bought, can last for a long time thanks to the sugar and canning process used to make them. Unopened, they can last for up to 1 year past the printed date, stored in a cool, dark place, like a pantry. Once opened, preserves should be kept in the refrigerator and can last for 6 months to 1 year. If you freeze your preserves, they can last for up to 2 years.
How do you tell if preserves is bad?
Preserves usually have a rich, fruity scent paired with their distinct sweet taste. If they begin to smell sour, fermented, or otherwise off, they have likely gone bad. Similarly, taste can be a giveaway; if they taste sour or unpleasant, you should throw them away. Texture is another signal. If you notice any mold, discoloration, or a slimy texture that wasn’t there before, those are sure indications that your preserves have gone bad.
Tips for storing preserves to extend shelf life
• Always store unopened preserve jars in a cool, dark place away from direct sunlight.
• After opening, always refrigerate your preserves. The cold temperature will slow down the growth of bacteria and mold.
• Always use a clean and dry spoon to take out preserves to avoid introducing bacteria into the jar.
• Consider dividing large quantities of preserves into smaller containers. This way, you consume the contents of one container without exposing the rest.
• Finally, if you're into freezing, you can freeze your preserves in airtight, freezer-proof containers to further extend their shelf life.
