Benvenuto de la Serna operates in Mendoza's Uco Valley, a region defined by high-altitude vineyards and intense sunlight that ripens Malbec and Cabernet Sauvignon to dark, structured wines. The winery's portfolio centers on these regional signatures. Trisagio Red Blend—a combination of Malbec, Tannat, and Petit Verdot—represents the winery's approach to blending, drawing on the valley's capacity for ripe, age-worthy reds. The Malbec and Cabernet Sauvignon bottlings stand as single-varietal expressions of what the Uco Valley terroir yields. Wine Enthusiast and Wine Spectator have assessed the range, with Trisagio Red Blend earning particular recognition among the three flagships.
