Mustard seeds, Shelf Life : Up To 2 Years When Stored Properly.

Yellow mustard seed is used as a spice and to flavor mustard condiment. There are approximately 40 different species of mustard plant. Three different types are generally used to make the mustard condiment. Black mustard (Brassica nigra) is the most pungent. White mustard (Brassica alba) is mostly mild and is used to make traditional American yellow mustard. Brown mustard (Brassica juncea) is dark yellow, has a pungent taste, and is used to make Dijon mustard. It is easier to harvest the brown mustard seed than the black mustard seed, so many mustard condiments now contain brown mustard seed instead of black mustard seed.*
