Do Frenchs® Mustards need to be refrigerated?
Dijon & horseradish mustard will lose their distinct flavors if not refrigerated, so we encourage refrigerating both. For all other mustards, refrigeration will help maintain flavor; however, it is not necessary to refrigerate if you prefer to consume your mustard at room temperature. There are no ingredients in mustard that spoil. “Refrigerate After Opening” is not required for food safety–we only recommended you do so to maintain optimal product flavor.
