Bodega Vistalba produces Malbec and Malbec-based blends from Mendoza, Argentina's premier wine region. The winery's flagship Tomero Parcela Única Malbec represents the upper echelon of the varietal, earning recognition from Wine Spectator, Wine Enthusiast, Wine Advocate, and Decanter. The Tomero Cuartel 41 Malbec and Corte C—a Cabernet Sauvignon and Malbec blend—round out the portfolio, each demonstrating the depth and structure that Mendoza terroir imparts to these grapes. Malbec thrives in Mendoza's high-altitude vineyards, where intense sunlight and cool nights build phenolic ripeness and acidity in balance. The winery's focus on single-varietal and blended expressions reflects the region's signature approach to winemaking.
