Does mustard go bad when refrigerated?

mustard is one of those items that does not have a set expiration date, so it's a little more challenging to know when the mustard is still safe to eat. For this reason, we recommend storing mustard in the refrigerator once opened. This will prevent the growth of bacteria and extend the shelf life.

Can mustard go bad in the fridge?

This is a common question on all levels of proficiency. The answer is yes, mustard can go bad at refrigerator temperatures. However, the shelf life of mustard is quite long (at least a year if it’s in a sealed jar or can). It’s also not going to “go bad” like a jar of spaghetti sauce might. When the jar or container is opened, it will continue to stay fresh on your shelf for quite some time.

Does store-bought mustard go bad?

While homemade mustard is great, store-banged mustard may not be as flavorful. Mustard is one of those foods that loses flavor when stored at room temperature, so homemade mustard may need to be refrigerated. If you are using mustard in other ways as well, such as as a sauce, it might not be a bad idea to refrigerate it anyway.

If homemade mustard goes bad, how long will it last?

Depending on the recipe, homemade mustard can last for up to two months at room temperature or up to two years refrigerated. Seedless varieties can last even longer—up to five years at room temperature and up to 30 years refrigerated.

Does homemade mustard go bad?

Like many other prepared foods, mustard is shelf-stable once it's been sealed in an airtight container, but it does go bad if it's left at room temperature or in the fridge for a long time. Although the shelf life of store-bought mustard is an estimated two to three years when properly stored, homemade mustard is more perishable. Once opened, the shelf life is reduced to about one month.
