Problably the fleshiest breed
Decades of breeding work at the Lower Austria Klosterneuburg School of Oenology has produced this red grape variety. In 1970, the hybrid between Zweigelt and Blaufränkisch was approved and named after the former director of the school, Dr. Leonhard Roesler (1839-1910).
This moderately early-ripening grape variety makes no special demands and provides consistently good quality. The dark, almost blue-black berries are very fleshy, and they yield extremely dark wines with high tannin content. Roesler is therefore often used for blends.
Around 10 hectares are planted with Roesler in Austria.
