How Long Does Plum Sauce Stay Fresh?
Storage Guide and Spoilage Indicators
Plum sauce lasts about 12 months in the refrigerator when stored properly.
Plum sauce is a versatile condiment known for its balance of sweetness and tanginess. Because it is fruit-based and contains vinegar, its longevity depends on maintaining an acidic environment and consistent refrigeration. While commercially bottled versions are highly stable, homemade varieties may require more careful monitoring. Once opened, the primary goal is to prevent oxidation and microbial growth by keeping the container tightly sealed and chilled. Understanding the visual and olfactory signs of spoilage ensures you enjoy the intended flavor profile without risking foodborne illness. By following proper storage protocols, you can maximize the shelf life of this pantry staple while maintaining its characteristic texture and deep color.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
