Petit Verdot is a red grape variety primarily grown in Bordeaux, France. It is known for its deep color, high tannins, and rich flavors, often contributing to blends rather than being used alone. The grape thrives in warm climates and is typically harvested late in the season, which allows it to develop complex flavors. In addition to Bordeaux, Petit Verdot is cultivated in various wine regions around the world, including California and Australia. It is often used to enhance the structure and aging potential of wines, adding notes of dark fruit, spice, and floral elements. Its unique characteristics make it a valuable component in many red wine blends.
