Didier Dagueneau was a winemaker in Pouilly-sur-Loire (Pouilly-Fumé wines) who has contributed much to putting Pouilly more clearly on the map for wine lovers. He started making in 1982 and became famous for his very concentrated sauvignon blanc based wines (Pur Sang, Silex). A contributing factor may also have been his very original cave man-like appearance with long hair and wild beard. Dagueneau died in September in a crash when flying an ultralight aircraft.
