Rheinhessen
The Rheinhessen wine region of Germany, is located just south of the Rheingau, along the Rhine River. It is the largest wine region of Germany, with more than 65,000 acres of vines. The climate here is mild, as temperatures are moderated by breezes from the river as well as nearby forests.

While Riesling is the most widely planted variety in the Rheinhessen, it is not as dominant as in other German regions. In fact, red varieties account for almost 30% of plantings here; these include Spatburgunder (Pinot Noir) and two unusual reds, Blauer Portugieser and Dornfelder, which is often made into a sweet red wine.

As with other wine zones along the Rhine, temperatures are moderate, resulting in wines of very good acidity and structure. Although Rheinhessen wines are not as famous as those from other German regions, the quality is among the best in the country. The finest examples of Riesling can age for a decade or more, while Sauvignon Blanc, with textbook herbal flavors, is an up and coming wine in this area. (Wine/Appellations)
