Mustard, a beloved condiment worldwide, is found in many refrigerators and pantries. But have you ever wondered if it has a shelf life? Does mustard go bad? Does dijon mustard go bad?

In this guide, we’ll explore the factors that contribute to mustard’s shelf life, how to tell if it has gone bad, and proper storage methods to prolong its freshness.

How Long Does Mustard Last?

When does mustard expire? Mustard’s longevity largely depends on its type, ingredients, and storage conditions. Typically, unopened bottles can last up to two years, while opened bottles can last up to one year in the refrigerator. However, homemade mustard or those with fewer preservatives may have a shorter shelf life.

Factors Affecting Shelf Life

Ingredients: Mustard made with vinegar, a natural preservative, typically lasts longer than mustard made with water or other liquids.
Type: Different types of mustard, such as Dijon mustard, honey mustard, and whole grain, may have varying shelf lives due to their unique ingredients and preparation methods.
Storage conditions: Proper storage can significantly impact mustard’s longevity. An opened jar should always be refrigerated and tightly sealed.

Signs That Your Mustard Has Gone Bad

While a relatively resilient condiment, it can still go bad. Here are some signs to watch out for when asking yourself “can mustard go bad”:

Color: If your mustard has darkened or changed color, it may be a sign of spoilage.
Texture: Clumps or a thickened texture may indicate that your mustard is no longer fresh.
Smell: An off or sour smell can be a clear indication that your mustard has gone bad.
Taste: If your mustard tastes stale or rancid, it’s time to discard it.
