Grey Poupon is a brand of Dijon mustard in the U.S. The brand of Dijon-style mustard was originally owned and marketed in the U.S. by the Heublein Company and now owned and manufactured by Kraft Foods. Like other Dijon mustards, Grey Poupon contains a small amount of white wine. It is made with brown mustard seed grown in Canada. The wine used is produced in upstate New York under the supervision of a rabbi, to ensure that the product maintains its kosher status. Grey Poupon became a popular mustard in the late 1970s and 1980s as American tastes broadened from conventional American yellow mustards. read more
