Rheinhessen (in English often Rhine-Hesse or Rhenish Hesse) is the largest of 13 German wine regions (Weinanbaugebiete) for quality wines (QbA and Prädikatswein) with under cultivation in 2018. Named for the traditional region of Rhenish Hesse, it lies on the left bank of the Rhine between Worms and Bingen in the federal state of Rhineland-Palatinate. Despite its historic name it is currently no longer part of the federal-state of Hesse, this being the case since the end of World War II. There have been several unsuccessful attempts to legally reunite the former wine growing districts of Mainz on the Hessian side during the post-war area. Rheinhessen produces mostly white wine from a variety of grapes, particularly Riesling, Müller-Thurgau and Silvaner, and is best known as the home of Liebfraumilch, although some previously underrated Rieslings are also made, increasingly in a powerful dry style. The wine region is a member of the Great Wine Capitals Global Network. The Rhine forms the eastern and northern boundary of the region, with the river Nahe to the west and the Haardt Mountains to the south. The Palatinate wine region lies to the south, the Rheingau lies across the Rhine to the north, and the Nahe wine region to the west. Known as the "land of the thousand hills", the terrain is undulating with vineyards mixed with orchards and other forms of farming. Its larger towns include: Mainz, Worms, Bingen, Alzey, Nieder-Olm and Ingelheim. In general the wines are best nearest the Rhine, where the soils impart more complex flavours. The best known area for white wines is the so-called Rhine Terrace (Rheinterasse; sometimes Rhine Front, Rheinfront) between Oppenheim and Nackenheim, which by itself is bigger than the whole of the Rheingau. A part of the Rhine Terrace, between Nackenheim and Nierstein is known as the Red Slope (Roter Hang) because of the presence of red slate. The main red grape area is around Ingelheim, in the north of the region opposite the Rheingau.
