The Calchaqui Valley is a high-altitude wine region located in the northwest of Argentina, in the province of Salta. The region is known for its unique terroir, characterized by its high elevation, dry climate, and sandy soils. The valley is situated between 5,000 and 10,000 feet above sea level, making it one of the highest wine regions in the world. The combination of high altitude, intense sunlight, and cool nights allows for the production of wines with intense flavors, high acidity, and a distinct minerality.
The main grape varieties grown in the Calchaqui Valley are Malbec, Cabernet Sauvignon, Tannat, and Torrontés. Malbec is the most widely planted grape in the region, and is used to produce full-bodied, intense red wines with flavors of dark fruit, spice, and earth. Cabernet Sauvignon and Tannat are also used to produce bold, structured red wines. Torrontés, a white grape variety native to Argentina, is used to produce aromatic, floral white wines with high acidity and a distinct minerality.
