The white grape variety (also Mainriesling, Würzburg N 1-11-17) is a new breed between Silvaner x Riesling (which was confirmed by DNA analyses carried out in 2012). It must not be confused with the varieties Riesel, Riesliner or Rieslina, which have similar names. The cross was made in 1921 at the Bavarian State Institute for Viticulture and Horticulture in Würzburg by Dr. August Ziegler (1885-1937). It was rediscovered in 1950 by Dr. Hans Breider (1908-2000), who vehemently advocated its distribution. She was a crossing partner in the three new breeds Albalonga, Fontanara and Montagna. With the same parents the three new breeds Multaner, Oraniensteiner and Osteiner were created. The late maturing, rather low-yielding vine tends to trickle. It produces a yellow-green, fruity wine with a taste similar to Riesling and ageing potential. In 2010 the variety occupied 87 hectares of vineyards in Germany.
