Hailing originally from Dijon, France, this pale, grayish-yellow mustard is known for its clean, sharp flavor, which can range from mild to hot. Dijon mustard is made from brown or black mustard seeds, white wine, unfermented grape juice (must) and various seasonings. The best-known maker of Dijon mustard is the house of Poupon, particularly famous in the United States for their Grey Poupon mustard.
