Isaac Fernández Selección is a collaborative project founded in 2010 by acclaimed winemaker Isaac Fernández Montaña and importer Aurelio Cabestrero to showcase old-vine indigenous grapes from Spain's forgotten terroirs. A nephew of the legendary Mariano García (former head winemaker at Vega Sicilia), Isaac spent over 25 years crafting elite wines at Bodegas Mauro before launching this personal venture. The winery focuses on minimal-intervention techniques to produce expressive, balanced wines across several prestigious regions, including Ribera del Duero, Rueda, and Rioja. Their philosophy centers on respecting the unique identity of each vineyard, often utilizing bush vines aged 60 years or older to achieve natural concentration and mineral depth.
