Mustard with Grape Must has a fruity and powerful taste. It is delicious with cold meats, duck breasts, blood sausages, in vinaigrettes, and in sauces. It can also be used like a chutney, with foie gras or cheese. This mustard is naturally made by finely grinding black mustard seeds with spices. To this spicy paste, our master mustard maker adds grape must, a concentrate of red grape grains. The red grape naturally colors the mustard, giving it this lovely purple hue. Very sweet, the red grape is the source of this incomparable sweet and savory flavor. 200g
