How does Argentina's high altitude affect its wine production?

According to the fact, Argentinian vineyards are located in highlands where the distance from the sea level varies between 1550 and 3000 meters. The altitude, together with the reduced heat contributes to cooler climate, which slow down ripening and insures acidity in the grapes. With the special terroir of this high-altitude production site, the wines have the opportunity to develop these intense flavors and aromatic properties that distinguish them from the wines from the lower level regions.
