In the German region of Württemberg, the common name for a Rotling produced by blending white and red grapes or their mash (but not their must or wine). However, the designation Rosé would not be permitted under EU wine law. Certain grape varieties are not prescribed. There are different versions for the meaning of the name. One of the most common is that the name was derived from the poet prince Friedrich von Schiller (1759-1805), who was born in Marbach in Swabia. This cannot be true, however, as the wine designation was used centuries before Schiller's lifetime. It is much more likely that the name derives from the shimmering colour of the wine. This name may also be used for quality sparkling wine or quality semi-sparkling wine if these products were only made from wine that was allowed to bear the name "Schillerwein". With regard to joint processing of white and red grapes, similar wines are Badisch Rotgold (Baden), Schieler (Saxony) and the Schiller (Switzerland).
