Expiration & Storage Tips
When does grape preserves expire?
Unopened store-bought grape preserves typically last 1-2 years past their printed date, as long as they're stored in a cool, dark location like a pantry, away from heat. Once opened, grape preserves need to be refrigerated and typically last between 6-12 months. If you've gone the homemade route, expect your preserves to be good for up to a year when unopened and kept in the refrigerator. If you freeze your preserves, they can last indefinitely, but for best taste use them within a year.
How do you tell if grape preserves is bad?
A couple of signs can tell you if your grape preserves have gone bad. Firstly, an off smell often indicates that it's time to toss the jar. Also, molds of different colors might start appearing on the surface - if this happens, no debate here, time to throw it away. Lastly, if the preserves naturally seep out of the jar with bulging lids - that's usually a bad sign as it indicates the development of bacteria, so it’s best to discard.
Tips for storing grape preserves to extend shelf life
• Always use a clean, dry spoon to take out the preserves to avoid introducing bacteria.
• Make sure the lid is tightly sealed after each use to preserve the freshness for longer.
• Avoid storing your grape preserves near the stove, dishwasher, or in direct sunlight. A pantry or cabinet away from heat sources is the best option.
• To extend the life of homemade grape preserves, it is helpful to use the canning method of preservation.
• Remember to refrigerate opened jars of grape preserves at all times, irrespective of whether they are store-bought or homemade.
• If you're planning to use the preserves for a longer period, you can consider freezing them. But it’s essential to leave some headspace in the container as the preserves will expand when frozen. Defrost overnight in the fridge when ready to use.
