Grape Guide
Zweigelt
RedZweigelt is Austria's leading red grape, a 1922 crossing of Blaufränkisch and Sankt Laurent that now covers roughly 13 percent of the national vineyard. Yield largely decides the style: generous crops give juicy, violet-tinged drinking wines, while restrained crops produce structured, barrel-aged reds built on sour and black cherry fruit.
Key Characteristics
- Crossing of Blaufränkisch and Sankt Laurent made in 1922 at Klosterneuburg
- Early budding and mid-season ripening, a little ahead of Blaufränkisch
- Vigorous and high-yielding, so canopy management and crop thinning are essential
- Prone to powdery mildew and to berry shrivel (Traubenwelke)
- Austria's most planted red grape and second overall after Grüner Veltliner

Overview
Zweigelt makes red wines of bright colour, ripe fruit and moderate tannin, with a texture that is soft rather than grippy. Young wines are typically red-violet in the glass, with aromas of sour cherry, blackberry and plum and sometimes a violet or peppery lift. The grape responds strongly to crop level. At high yields it gives light, fruity, early-drinking reds with little structure; at low yields it can deliver density, depth and a firmer tannic frame that rewards oak maturation and several years in bottle. The variety suits both simple and ambitious winemaking. Many bottlings are unoaked or see only large old casks, aimed at freshness and immediate fruit. Serious versions are aged in barriques or larger wood and show black cherry, dark chocolate and spice. Its generous fruit and reliable colour also make it a frequent component in red blends, where it is often paired with Blaufränkisch or Cabernet Sauvignon for added structure.
Origins & History
Zweigelt was bred at the federal viticulture research institute in Klosterneuburg, close to Vienna, where Fritz Zweigelt made the cross in 1922. The parents are Blaufränkisch and Sankt Laurent, two varieties long established in Central Europe. The breeder first called his new vine Rotburger, and Austrian labels still carry that name as a synonym. Some time in the 1970s the vine officially took its creator's surname instead, a change Lenz Moser had long argued for so the crossing would be named after its breeder; sources give different years, but by 1978 the official list named it Blauer Zweigelt, with Rotburger kept only as a synonym. Genetic testing has backed up the parentage. Blaufränkisch descends from Gouais Blanc, and Sankt Laurent is believed to be a Pinot offspring. That makes Zweigelt a grandchild of both Gouais Blanc and Pinot, linking it to the family tree of many Western European varieties. Plantings grew slowly at first, then expanded quickly during the second half of the twentieth century, thanks to dependable ripening, deep colour and generous yields. Between 2000 and roughly 2010, Austrian vineyard area under the variety rose by nearly half, and today Grüner Veltliner is the only grape planted more widely in Austria. Zweigelt has also been used in breeding: Roesler, bred in Austria, and Cabernet Moravia, from the Czech Republic, both count it among their ancestors.
Viticultural Characteristics
Zweigelt buds early and ripens in mid-season, ahead of Blaufränkisch, which makes it more dependable in cooler or less favoured sites. Vigour and productivity are high, so quality depends on disciplined viticulture: restricted pruning, shoot and leaf management, and green harvesting or bunch thinning to bring yields down. Left unchecked, the vine over-crops and the wines turn thin and herbaceous. Powdery mildew is a recurrent threat, and the variety is notably susceptible to berry shrivel (Traubenwelke, also called grape wilting), a disorder that can reduce yields and distort ripeness in affected seasons. It adapts to a wide range of soils, from the heavy loams and loess of the Weinviertel to the gravels and sands around Lake Neusiedl, and is hardy enough to be grown in northern, cool-climate regions.
Wine Styles & Characteristics
Austrian Zweigelt falls into two broad categories. The first is a youthful, unoaked red, fermented in stainless steel or large wood and bottled early, with red-violet colour, purple-fruit aroma, soft tannin and moderate alcohol. It is produced in large volumes and is typically served lightly chilled or at cellar temperature with casual food. The second is a concentrated, oak-matured red from low-yielding vineyards, fuller in body, with sour or black cherry fruit, spice and firmer structure that can develop over five to ten years or more. Appellation rules reinforce the distinction. In the Neusiedlersee DAC, a wine labelled Classic is a dry, unoaked-leaning expression, while Reserve wines are pure Zweigelt or blends with a Zweigelt majority of at least 60 percent, matured in wood and carrying a stated minimum of 13 percent alcohol. Carnuntum producers use the Rubin Carnuntum label for a Zweigelt-based, fruit-forward style. Zweigelt is also vinified as rosé and, in some cases, as a sparkling base.
