Nicolas Catena dared to plant vines where no one thought they would ripen. His high-altitude wine revolution culminated in the discovery of a new terroir for wine, the Adrianna Vineyard, at almost 5,000 feet elevation. \n\nHe discovered that the average temperature decreases with higher altitudes, and the diurnal range increases. The cooler climate at this extreme elevation preserves natural acidity and increases polyphenols, while the intense mountain sunlight strengthens the tannins, producing wines of incredible depth and complexity. The wines consistently prove to have more minerality and acidity than wines from other sites in the Southern Uco Valley at lower altitudes.
