Why Is Uco Valley So Renowned for Its Wines?
Located about 100 km south of the city of Mendoza, Uco Valley has become the epicenter of Argentina’s high-end wine scene. Sitting between 900 and 1,600 meters above sea level, this mountain terroir offers ideal conditions for producing fresh, intense, and elegant wines. Dry climate, significant temperature variations, and mineral-rich soils (with sand, stone, clay, and limestone) set the perfect stage for crafting high-altitude wines with a strong identity.
It’s no coincidence that demand for Uco Valley wines keeps growing. Renowned winemakers, visionary architects, and committed producers have positioned this region among the world’s most prestigious.
A Brief History: From Agricultural Zone to International Icon
For decades, Uco Valley was just another winegrowing area in Mendoza. But in the 1990s, a new generation of producers began to study its altitude, microclimates, and soil diversity in detail. This led to the recognition of zones like Gualtallary, Altamira, and Los Chacayes, now protected by official designations of origin.
Thanks to its strategic location and cutting-edge technology, Uco Valley now produces high-altitude wines that rival the greats of Burgundy, Napa, and Tuscany.
