Auxerrois blanc
auxerrois blanc de laquenexy
Auxerrois blanc or Auxerrois Blanc de Laquenexy is a white wine grape prevalent in the French region of Alsace, and is also grown in neighbouring Germany and Luxembourg. It is a full sibling of Chardonnay that is often blended with the similar Pinot blanc. Auxerrois blanc is thought to have originated in Lorraine, rather than near Auxerre in the Yonne. Recent DNA fingerprinting suggests that it is a cross between Gouais blanc and Pinot, the same ancestry as Chardonnay. The name Auxerrois blanc has been used as a synonym for Chardonnay in the Moselle region in France, which may explain why there is also a longer name (Auxerrois Blanc de Laquenexy) for the grape variety. Auxerrois blanc is seldom seen in the Americas, though is somewhat grown in North America and South Africa.[according to whom?]
