Weinert produces wines from Mendoza, Argentina's premier wine region. The winery's portfolio centers on Malbec, the varietal that defines the region's character—deep, structured, and capable of remarkable aging potential. Tonel Unico 248 Malbec stands as the flagship expression, a wine that has earned recognition from Wine Advocate, Wine Enthusiast, Decanter, Wine Spectator, and Falstaff. The Reserve Montfleury Chardonnay demonstrates range beyond red varietals, while Carrascal Corte Clásico—a blend of Merlot, Cabernet Sauvignon, and Malbec—showcases the winery's approach to Bordeaux-style composition adapted to Mendoza terroir. These wines reflect the region's high altitude, intense sunlight, and continental climate, which together produce wines of concentration and definition.
