How Long Does Yellow Mustard Last?
Keep your condiment shelf fresh with proper storage tips.
Yellow mustard lasts about 1 year in the refrigerator.
Yellow mustard is a staple condiment known for its tangy flavor and long shelf life. Because of its high acidity and vinegar content, it acts as a natural preservative, making it much more stable than dairy-based spreads. When kept in a sealed container in the refrigerator, yellow mustard remains safe to eat for many months, often lasting up to a year. While the flavor may eventually dull or develop a slightly different profile over time, the safety of the product remains high due to its acidic environment.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
