TerroirArgentina’s Napa Valley
The Uco Valley is one of the most visually captivating wine regions in the world. Over the past 25 years it has become the most exciting terroir in Argentina, and one of the southern hemisphere’s most talked about wine regions.
Alluvialsand, stone, clay, rock
Our vineyards are at 3,600 feet elevation and are still dominated by the towering Andes.
The mountains provide natural irrigation from meltwater and rivers like the Tunuyán. Over geological time, erosion of these peaks created a landscape and soil profile perfect for viticulture.
With more than 250 sunny days annually, and average temperatures of 57 °F, we benefit from natural dryness that deters pests and rot.
The Uco Valley’s altitude and dry air create diurnal temperature variation in the summer. Hot daytime temperatures build intense color and aroma, while cool nights maintain acidity and freshness in the grapes.
Uco Valley soils are alluvial – composed of sand and stony surface layers, with a base of clay and rock.
Drainage is natural with some moisture retention for the deep roots. This naturally stresses the vines to reduce plant vigor and increase flavor concentration in the fruit.
We practice traditional hand harvesting to preserve the best quality fruit.
During the growing season we lower yields to 2-3 tons per acre through green harvesting. This reduces the number of clusters per vine, and intensifies flavor in the grapes. It takes skilled viticulturists who understand the Uco Valley’s Terroir and what the vines need each growing season.
