Which two factors are crucial for producing high-quality grapes in Mendoza?

The factors that are crucial for producing high-quality grapes in Mendoza are snow-melt water from mountains and high altitude. Mendoza is located at the foothills of the Andes Mountains, where snowmelt from these mountains provides a vital source of irrigation for vineyards. This melting snow helps ensure a consistent and high-quality water supply, which is essential for vine health and grape development.

The high altitude of Mendoza’s vineyards plays a significant role as well. Vineyards at higher elevations experience more sunlight and cooler temperatures, which contribute to the development of thicker-skinned grapes. These conditions also help to preserve acidity in the grapes while promoting the development of complex flavors and aromas—both of which are essential for high-quality wine production.

In combination, snowmelt provides the necessary irrigation, while high altitude influences the growing conditions, making these two factors fundamental in producing the excellent quality grapes for which Mendoza is known.
