A slightly different wine-producing region in southwest Germany, bordering Alsace and Switzerland, where Riesling is not the major player. Formerly an independent grand duchy, Baden became in 1952 part of the German federal state Baden-Württemburg. Some 16,000 hectares under vines make Baden the third-largest wine-producing district in Germany. Baden's sub-regions are the Badische Bergstrasse, Bodensee, Breisgau, Kaiserstuhl, Kraichgau, Markgrafler Land, Ortenau, Tauberfranken and Tuniberg. White grape varieties are Grauburgunder (Rulander), Müller-Thurgau, Bacchus, Gutedel, Kerner, Klingelberger (Riesling), Scheurebe, Muskateller, Nobling, Auxerrois, Weißburgunder, Silvaner, Gewürztraminer—with the Pinot Gris (Grauburgunder if dry, Rulander when sweet), Pinot Blanc (Weissburgunder) and Müller Thurgau being the most important. The most prominent red variety is Spätburgunder (Pinot Noir), which ripens very impressively in the sunny and warm climate. Other important reds are Schwarzriesling (Pinot Meunier) and Dornfelder.
