Blauburger

Dr. Fritz Zweigelt created Blauburger in 1923 at the Federal Institute for Viticulture and Pomology in Klosterneuburg, Austria. The cross of Blauer Portugieser and Blaufränkisch was developed specifically to produce wines with intense color and to reduce the industry's reliance on imported coloring additives. Blauburger was bred just one year after Zweigelt created the variety that now bears his name, representing an effort to find an even better red grape for Austrian conditions. DNA analysis conducted in 2013 confirmed the parentage of the variety.

• Breeding number registered as Klosterneuburg 181-2
• Goal was intense color production and reduced need for imported additives
• Bred one year after Zweigelt (Rotburger), as a continuation of the same research program
• DNA analysis in 2013 officially confirmed Blauer Portugieser x Blaufränkisch parentage

Blauburger is planted across 418 hectares in Austria as of 2024, making up roughly 0.9% of Austrian vineyards. The variety concentrates in Niederösterreich (Lower Austria), with the Weinviertel region being its primary home. Blauburger is an adaptable variety that places few demands on soil type, and its early-ripening character suits cooler sites where traditional red varieties struggle to achieve full ripeness. Beyond Austria, Blauburger is extensively grown in Hungary and in Germany, where it is permitted as a component in Egri Bikavér wines.

• Primary home is Niederösterreich, particularly the Weinviertel region
• 418 hectares in Austria; also grown extensively in Hungary and Germany
• Adaptable to various soil types with no specific soil requirements
• Early-ripening character suits cooler climates where other red varieties struggle

Blauburger produces dark red wines that are rich in extract with a notably neutral flavor profile. The variety is characterized by its bluish-black berries and the deep, dark color it imparts to wine. Aromas lean toward soft berry notes, predominantly elderberry, with a velvety and harmonious texture on the palate. Low acidity and low tannins give the wines an approachable, smooth character. Because of its extraordinary color intensity rather than aromatic complexity, Blauburger is rarely bottled as a standalone varietal wine and serves primarily as a blending partner to enhance color in red wine production.

• Deep, dark color is the grape's defining winemaking asset
• Flavor profile is neutral with soft elderberry aromas
• Low acidity and low tannins create a velvety, harmonious texture
• Functions mainly as a blending component rather than a varietal bottling

Blauburger holds official status as one of 13 red grape varieties permitted for quality wine production in Austria. In Hungary, the variety is permitted as a component in Egri Bikavér, the traditional red blend known internationally as Bull's Blood. Notable producers working with the variety include Matthias Hager in Austria. The variety is susceptible to powdery mildew and fungal diseases, which adds a management burden for growers and partly explains its relatively modest footprint within Austrian viticulture.

• One of 13 permitted red varieties for Austrian quality wine
• Permitted component in Hungarian Egri Bikavér (Bull's Blood)
• Matthias Hager is a notable Austrian producer
• Susceptibility to powdery mildew and fungal disease limits wider adoption
