Districts: pinot grigio is planted extensively in the Venezia and Alto Adige regions of Italy. Pinot grigio is also grown in the western coastal regions of the U.S.A. It is called malvoisie in the Loire Valley and pinot gris in the rest of France. In Germany and Austria pinot grigio is known as the Ruländer or Grauer Burgunder. Similar aliases are used in the german settled regions of Australia.
Typical taste: crisp, dry wines with good acid “bite” are typically made in Italy and Germany. Oregon or Alsace Pinot Gris shows aromatic, fruity flavors. Pairing with food is more difficult because Alsatian winemakers leave the grapes on the vine much longer. The perfume in Alsatian Pinot Gris makes it especially well suited for Thai or spicy Chinese cuisine.
