Tusk Estates is positioning itself as one of Napa Valley’s 21st century cult wines. It was founded in 2007 by Tim Martin, a long-time Napa Valley food and wine marketer and entrepreneur; Michael Uytengsu , a former investment banker and heir to an international food conglomerate; and Philippe Melka, a French-born winemaker and international consultant. Tusk sources grapes from Napa Valley vineyards and calls itself “the next great luxury brand.” Tusk makes only about 150 cases a year and produces a single Cabernet Sauvignon.
