Valle de Uco, in the Tunuyán and Tupungato departments southwest of Mendoza, Argentina, is a high‑altitude viticultural zone at the foothills of the Andes. Since the 1990s and 2000s it has become a focus for premium winemaking, with modern wineries and investment emphasizing site expression. Wines are defined by cool nights, strong diurnal shifts and concentrated fruit with clarity and finesse; producers favor terroir-driven Malbecs and also excel with elegant Cabernet Sauvignon and refined white varieties. The valley’s combination of elevation, clean mountain water and careful vineyard management gives wines that balance power with freshness and mineral lift.
Valle de Uco features semi-arid, continental climate with strong diurnal temperature variation due to elevations roughly 900–1,500 meters. Soils are predominantly alluvial—sand, silt and clay—with pockets of gravel and limestone; vineyards sit on gentle to steep slopes benefiting from good drainage and sun exposure. Irrigation relies on Andean meltwater, and the high UV and cool nights promote thick skins, acidity retention and clear varietal definition.
