Rieslaner is an important cross between two white grapes, Riesling and Silvaner. Created in 1921, Rieslaner was designed to have good results when exposed to botrytis (the same rot that is the "secret" ingredient in Sauternes). Although it is found in dry wines, Rieslaner's astronomically high acidity and full bouquet of flavors make it one of the world's best sweet wine grapes.
The best regions for Rieslaner are in Germany, where it was created. Franconia and Pfalz are the main areas for the growth of this grape, but Rheinhessen has also produced good examples.
