Uco Valley

Uco Valley is a protected wine-origin designation in Argentina, anchored in the existing wineknowledge region row for mendoza. It belongs in the appellations layer because it describes the legal name that may appear on labels, while any broader region row remains geographic and cultural context.

Characteristic grapes include Malbec, Cabernet Franc, Cabernet Sauvignon, Chardonnay, Semillon, Sauvignon Blanc, Pinot Noir. The wines often show dark fruit, violet, herbs, mineral tension, firm acidity, and polished tannin, with altitude shaping freshness. The grape list is a practical orientation rather than a claim that every bottle uses every variety.

Argentina's GI framework protects the origin name; Uco Valley is a high-altitude Mendoza subregion rather than a single required grape style. The rules protect origin and labeling, while producer choice, vintage, site, and cellar decisions still determine the final wine.

The IG adds a necessary Mendoza sub-origin beneath the broad Mendoza row. For EncyclopediaOfWine, the row keeps the legal designation separate from the larger region and from grape-variety reference content.
