Alpasión is situated in Tunuyán, the heart of Mendoza's Uco Valley—a region defined by high altitude, mineral soils, and diurnal temperature swings that sharpen varietal expression. The winery focuses on Bordeaux varieties and Malbec, Argentina's signature red. Its Grand Malbec achieves depth and structure characteristic of the region's flagship grape, while Grand Petit Verdot and Grand Cabernet Franc demonstrate the valley's capacity for secondary varieties. These wines have been assessed by Wine Spectator, Wine Enthusiast, Decanter, Wine Advocate, and Falstaff. Tunuyán's terroir—cool nights and intense sun—produces reds with both power and precision, qualities evident in Alpasión's portfolio.
