True, you can find Maille gourmet mustard all over the place, but you can only get it hand-pumped here in the official boutique. Pumped fresh into a genuine stoneware pot and sealed with a cork, it has an altogether different taste, and it is delicious. Choose from mustard made with a dash of Chablis, Chardonnay, Sauternes, or splurge on Chablis with truffle bits.
