Zweigelt was developed in 1922 and is a red wine grape variety that is widely grown in Austria, although it does have a presence in Canadian vineyards. The most widespread red wine varietal in Austria, Zweigelt ranges from young-drinking wines that are non-wood matured producing firm and strong red wines. Zweigelt is a cross of St. Laurent and Blaufrankisch, and is a heavy producer that can yield five to six tons of fruit per acre. Zweigelt requires little soil, but because it is a fertile grape, requires intensive leaf work and yield regulation. Zweigelt produces wines that are slightly reddish and violet with soft tannins. The mature and full-bodied wines are long-living, delivering morello cherry tones. Zweigelt is darker than Pinot Noir with subtle hints of fruit that are not overwhelming. The fruity and smooth flavor gives way to a spicy bite with an intense and slightly astringent finish. Zweiglet is an early ripening grape and is the most commonly consumed red wine in Austria. The grape makes for a mellow and easy-drinking wine with faint tannins and cassis fruit and cherry flavors. With very little bite and no hard edges, the grape produces 13.5% alcohol by volume.
