Franz Hirtzberger and F.X. Pichler are the two greatest producers of the Wachau and arguably of dry white wines in Austria. Located in the tiny village of Spitz, surrounded by mountains and the Danube, Hirtzberger makes Riesling that tastes like pure minerality and precision. His terraced vineyard names—Hochrain, Singerriedel, Steinporz—are synonymous with the greatest wines of the region.
