Zweigelt
The Zweigelt , also known as Rotburger, is an Austrian hybrid grape variety created in 1922 by Friedrich Zweigelt (1888–1964), who later became Director of the Federal Institute and Experimental Station of Viticulture, Fruit Production and Horticulture (1938–1945). Zweigelt is a crossing between the St. Laurent and Blaufränkisch grape varieties. Widely planted in Austria, Zweigelt vines have made inroads in the Canadian wine regions of Ontario's Niagara Peninsula and of British Columbia, with limited plantings in Hungary, Australia and New Zealand. In the Czech Republic it is known as Zweigeltrebe and is the third-most widely planted red-grape variety, comprising approximately 4.7% of total vineyards. It grows in most of the wine regions in Slovakia. As of 2010[update], newly established Belgian and Polish vineyards have also started to plant Zweigelt. As of 2014[update], Washington state has several small plantings (only a few acres) of Zweigelt, including Wilridge Winery and Perennial Vintners. Zweigelt is also known as Rotburger (not to be confused with Rotberger), Zweigeltrebe, and Blauer Zweigelt.
