Italian 

Italian Pinot Grigio is usually light to medium-bodied, clean, dry, and refreshing with mild hints of white peach and pear.

Alsace, France

French Pinot Gris (mostly from Alsace) is richer and fuller flavored with intense aromatics of ripe peaches, honeysuckle, and quince. Although usually dry, they can seem sweeter due to the ripeness of the fruit and the intensity of the perfume.

New World

New World Pinot Gris typically falls somewhere in between style-wise, not as rich as Alsace but not as light as Italy. The goal is usually a crisp, refreshing wine that also offers enough obvious succulent fruit to appeal to the average New World white wine drinker.
