Clos d'Agon produces wines from Catalunya, where Mediterranean climate and diverse terroir support both traditional and expressive varieties. The winery's portfolio centers on two distinct expressions: a red blend anchored in Cabernet Franc, Petit Verdot, and Cabernet Sauvignon, and white wines built from Viognier and Rhône-style blends of Marsanne, Viognier, and Roussanne. The Selección Especial demonstrates the structure and depth possible from the region's Cabernet varieties, while the Viognier and Blanco showcase the aromatic potential of white grapes in this Mediterranean setting. Decanter, Falstaff, and Wine Advocate have assessed the winery's output, reflecting serious engagement with both red and white production.
