This is a white grape variety of the Vitis vinífera species and it is thought to be a mutant clone of the Pinot noir grape. Wines made from this grape exhibit a color ranging from deep golden yellow to coppery including a pink hue. The clone of Pinot Gris found in Italy is known as Pinot Grigio. It is supposed that Pinot Gris was the favorite grape of the emperor Carlos IV, who made Cistercian monks take blends of this variety to Hungary. Later, this vine was called Szürkebarát, meaning “grey monk”. Researchers from the California University in Davis have determined that Pinot Gris grape has a similar DNA profile to Pinot Noir grape and the color difference derived from a genetic mutation occurred a few centuries ago. Leaves and plants of both vines are very similar, being the color the only feature to differentiate one from another.
