Expiration & Storage Tips
When does peach jam expire?
Unopened store-bought peach jam can last between 1 to 2 years past the 'best by' date printed on the jar, as long as it's stored in a cool, dry place. Once you open the jam, it should be refrigerated and typically lasts for about 1 month. If you've made homemade peach jam using proper canning methods, it can last up to a year in the pantry, and up to a month after opening when stored in the refrigerator. If you choose to freeze homemade peach jam, it can be stored up to a year, but should be promptly consumed after defrosting to ensure maximum freshness and taste.
How do you tell if peach jam is bad?
Look out for these signs to tell if your peach jam has gone bad. If the color has darkened significantly, or you notice a thick, fuzzy layer of mold on the surface, the jam has likely spoiled. It's also important to check the texture and smell. If the jam has become extremely thick or gummy, or it gives off a sour or off-putting smell, it's time to toss it. Additionally, if the jar lid is bulging or the jar has an unusual pop when opened, these are sure signs that your jam is compromised and it's no longer safe to eat.
Tips for storing peach jam to extend shelf life
• Store unopened peach jam in a cool, dry place. This can be a pantry, cupboard, or basement where temperatures stay consistent.
• After opening, always refrigerate your peach jam. Make sure to seal the jar well before placing it back in the fridge.
• When using the jam, use a clean spoon every time to prevent introducing bacteria into the jar.
• For long-term storage, homemade peach jam can be canned using proper techniques or frozen. If freezing, use airtight containers, leaving 1/2 inch headspace to allow for expansion.
• When you're ready to use your frozen peach jam, thaw it in the refrigerator for a few hours or overnight for best results.
