Expiration & Storage Tips
When does stone ground mustard expire?
Stone ground mustard usually lasts for about a year if unopened and stored correctly. The 'best by' date on the jar should provide a useful guideline. However, once opened, it should be consumed within 2-3 months for optimal flavor, though it can technically last in the refrigerator for up to a year. If frozen, stone ground mustard can exceed its usual shelf life by several months, but its texture might change on defrosting.
How do you tell if stone ground mustard is bad?
A few ways to tell if your stone ground mustard has gone bad are if it develops an off smell or if you see mold in the jar. A change in the mustard color, usually becoming darker, could also suggest it's going bad. Remember, consume your mustard sooner rather than later once opened, to enjoy its ideal flavor.
Tips for storing stone ground mustard to extend shelf life
• Store your unopened jar of stone ground mustard in a cool, dry place away from sunlight.
• Upon opening, store your mustard in the refrigerator to maintain its flavor and longevity.
• If you choose to freeze your mustard, place it in an airtight container labelled with the date. This will help prevent freezer burn and keep track of how long it’s been frozen.
• Always use a clean, dry utensil when scooping out mustard to avoid introducing bacteria into the jar, which can accelerate spoilage.
• Consider buying smaller jars if you use this condiment infrequently, to ensure it remains fresh.
