Uco Valley
The Summit of Andean Terroir
"Where the cold of the Andes sculpts elegance: the epicenter of the Argentine wine revolution."
The Geology of Altitude
The Uco Valley, in Mendoza, is synonymous with precision viticulture. As highlighted by Wines of Argentina, its identity is forged in alluvial soils rich in calcium carbonate, a geological rarity that yields wines with unique tension and minerality. Here, extreme altitude and the purity of sunlight allow for perfect phenolic ripeness without losing natural freshness.
This region leads the creation of Geographical Indications (GIs) in the country, a territorial delimitation system endorsed by the National Institute of Viticulture. By exploring micro-regions like Gualtallary or Paraje Altamira, consumers discover a modern interpretation of Malbec: less jammy and with more vertical texture.
Terroir Curation
High-Altitude Malbec
Far from heavy power, Uco Malbecs stand out for their notes of violets and blue flowers. Renowned critics at Robert Parker Wine Advocate have frequently pointed to this area as the origin of the highest scores for South America due to its elegance and freshness.
Mineral Chardonnay
European-profile whites, with a marked citrus nerve and calcareous salinity. The technique behind these whites is analyzed by educational portals such as Wine Folly, highlighting the influence of chalky soil on the wine's texture.
Questions about Uco Valley
Why are "calcareous soils" mentioned?
Different studies on viticultural geology in Decanter explain how the calcium carbonate accumulated in the roots imparts that "chalky" sensation in the tannins, allowing for superior palate cleansing.
What is the best serving temperature?
To highlight the citrus vivacity of Chardonnays and the floral freshness of Malbec, we recommend following WSET standards, keeping high-altitude reds between 15°C and 17°C.
