Does mustard have to be refrigerated after opening?

I’ve seen mustard in the refrigerator section of the grocery store, and although I know it’s in a sealed container, I wonder if it’s ever been opened before. Most brands of mustard will keep well in the refrigerator for about three months after opening, but if you want to keep it longer, you can freeze it.

Can mustard be kept at room temperature after opening?

Yes, mustard generally does not need to be refrigerated after opening. Once opened, mustard should be stored in an airtight container at room temperature. Refrigerated mustard will likely have a shorter shelf life. Refrigerated mustard will last about four to six weeks.

Can you leave out mustard after opening?

The short answer is yes. Once the seal is broken, you can leave the jar of mustard out at room temperature for about two to three weeks. Re-seal the jar when you’re done using it. However, the jar should be tightly sealed, as the shelf life decreases with an opened jar.

Mustard that’s been refrigerated after opening will keep for two to three weeks. If you need to use it before that, put the jar in an airtight container and store it in the freezer.
