Rotberger
From Biocrawler, the free encyclopedia.
Rotberger is a wine grape. Its parentage is not known but it is thought to be from a cross of Trollinger and Riesling grapes. Dr. Heinrich Birk (1898-1973) produced the cross at the Geisenheim research institute in 1928. It is used to produce fruity, early maturing light red wines in cool-climate areas. It is often best drunk when young and can be used to produce a rosé or sparkling wine. It has no relationship with the Rotburger variety bearing a nearly similar name which is also known as Zweigelt.
