A grape varietal, used in the production of red wine, originating in Austria. The Blauer Zweigelt varietal is a cross between Blaufränkisch (Blauer Limberger) and St. Laurent, a hybrid developed by Dr. Zweigelt at the Kosterneuburg research station in 1922. Primarily grown in Austria, Canada has begun to cultivate the varietal and is expected to do well given the similar climates of Austria and Canada.
