Viejo Solar produces wines from Mendoza, Argentina's premier wine region. The winery focuses on varietals that thrive in the region's high-altitude terroir and intense sunlight: Bonarda, Malbec, and Torrontés. Bonarda, the winery's flagship red, brings the dark fruit and spice characteristic of the variety, while its Malbec expresses the structure and depth that define Mendoza's signature expression. The Torrontés offers the aromatic white alternative—a crisp, floral counterpoint to the reds. These wines have been reviewed by Wine Spectator, Wine Enthusiast, Wine Advocate, and Falstaff, reflecting their standing within the broader conversation around Argentine wine.
