Auxerrois is the name of a low-acid white grape widely planted in Alsace, as well as in Germany and Luxembourg. It is also the name used for the black Malbec grape in Cahors, where it is the principal wine grape. The list goes on: Pinot Gris is known as "Auxerrois Gris" in Alsace, and at one time Chardonnay was called "Auxerrois Blanc" in the Moselle region (though this last term fell into disuse after Chardonnay's huge boom in popularity). Alsatian Auxerrois is used in Crémant d'Alsace, and in blends labeled "Pinot Blanc."
