Folle blanche was the traditional grape variety of the Cognac and Armagnac regions of France. It is also known as Picpoule (with various variations of spelling (Piquepoul, Picpoul), although it is in fact unrelated to the Picpoul of the Languedoc) as well as Gros Plant and Enrageat blanc. Folle blanche is an offspring of Gouais blanc, with the other parent so far unidentified.
