Proemio produces wines from Mendoza, Argentina's premier wine region. The winery's portfolio centers on Bordeaux and Rhône varieties adapted to the region's high-altitude terroir. The Barrel Selection, a Cabernet Sauvignon–Malbec–Petit Verdot blend, represents the winery's core expression, while the Grand Reserve Winemaker's Selection Tinto layers Shiraz, Cabernet Sauvignon, Merlot, and Malbec into a more complex structure. A Reserve Single Vineyard Cabernet Franc rounds out the range, showcasing the varietal's herbal and mineral character in Mendoza's continental climate. Wines from Proemio have been assessed by Wine Enthusiast, Wine Spectator, Decanter, Wine Advocate, and Falstaff.
