The Ortega Gil-Fourmier family created the domain O. Fournier at the foot of the Andes in Argentina in 2000. Mendoza is the most reputed viticultural region in Argentina as it boasts terroirs at exceptional altitudes. O. Fournier is located in Mendoza in an area named Valle de Uco (between 900 and 1250m of altitude). There is a majority of Malbec and Tempranillo. The domain takes advantage of the malleability of varietals to produce medium-bodied wines such as the cuvées Uco and Beta, as well as powerful and structured wines such as the cuvée Alpha.

The Alpha Crux Blend cuvée consists primarily of Malbec, associated with Tempranillo, Cabernet Sauvignon and Syrah. This was the first domaine in Argentina to plant Tempranillo. The wine is aged for 18 months in barrels made of 80% French oak and is unfiltered. The dark colour indicates a wine with a fine structure. The dark berry nose also has a light floral subtext. It is full, harmonious and taut on the palate, with a toasted cocoa and leather finish. Barrel ageing ensures good longevity.
