Cono Sur operates in the Maipo Valley, a subregion of Chile's Central Valley near Santiago known for structured red wines. The winery's Single Vineyard Cabernet Sauvignon demonstrates the region's capacity for depth and complexity in this classic varietal, while its Single Vineyard Syrah captures the darker fruit and spice that Syrah expresses in this terroir. The 20 Barrels Limited Edition Carmenere—a grape with deep roots in Chilean viticulture—rounds out the portfolio with the varietal's characteristic dark plum and herbal character. These wines have been assessed by Wine Advocate, Wine Spectator, Decanter, Falstaff, and Wine Enthusiast.
