Pinot Gris and Pinot Grigio are actually the same white grape. Two different names. In Italy and California it's known as Grigio, and in Oregon and France it's known as Gris. Other regions use the terms interchangeably. This is a mutation of the Pinot Noir grape, which is red. Pinot Blanc is not the same as Pinot Gris or Pinot Grigio - it is a further mutation of this varietal. The Italian version is typically dry and light, with a mineral taste to it. California's output can be richer in flavor, but still have the mineral taste. Often, they finish with a lemony or citrus flavor. French Pinot Gris wines usually come from the Alsace region. These are more fruity and flowery, though they still have that mineral aroma. Flavors can range from peach to grapefruit to melon. It's also known as Rulander or Grauer Burgunder. It can be used to create both fine whites and rosés.
