Palo Alto produces wines from Mendoza, Argentina's premier wine region. The winery focuses on Malbec, the varietal that defines the region's character—deep, structured, and rich with dark fruit. The Malbec and Reserva Malbec showcase the grape's core expression, while the Alucha Gran Reserva Blend adds complexity through a combination of Ancellotta, Malbec, and Cabernet Sauvignon. Wine Enthusiast, Wine Spectator, and Wine Advocate have all rated Palo Alto's portfolio, with the Alucha Gran Reserva Blend earning particular recognition among prestige critics.
