FX Pichler is the king of Gruner Veltliner and not only that. Though his Gruner Veltliners may be the real revelation, but his highly concentrated Rieslings and his Sauvignon blanc are equally famous and will age very happily for many years, if not decades. Pichler shares a distrust of very reductive vinification and high technology with other Wachau growers, believing that these would make his wines too uniform. He ferments them in large wooden barrels and leaves them there for about six months. Industrial yeasts are only used for the first consignment of must; after that, natural yeasts take over. --Philipp Blom, Wines of Austria
