What is the difference between Pinot Gris and Pinot Grigio?

Pinot Gris and Pinot Grigio represent not only a different language, but a different wine style as well. The French variety, Pinot Gris, is best known for the soft, aromatic wines it produces in Alsace, Franc. Pinot Grigio, the Italian name for the grape, produces wines that are crisper, more citrus-driven in avor, and lighter bodied in style. Outside of France and Italy, producers of the grape use the name (Pinot Gris or Pinot Grigio) that best represents the style they are aiming to create.
