Zweigelt is recognized as the most widely planted red grape variety in Austria. This grape, a cross between Blaufränkisch and St. Laurent, was developed in the 1920s and is known for producing approachable wines that can display a range of fruit flavors, such as cherry and plum, often with some spice and earthiness. The popularity of Zweigelt in Austria is due to its adaptability to the country's climate and soils, as well as its favorable characteristics for both varietal and blended wines.

In contrast, while Blaufränkisch is important and widely planted, it does not surpass Zweigelt in terms of total acreage. Grüner Veltliner, although extremely significant as Austria's leading white grape, is not a red grape variety, thus making it irrelevant to the question. St. Laurent, another notable red variety in Austria, has a smaller planting area compared to Zweigelt and is generally more focused on niche markets. Therefore, Zweigelt’s prevalence in Austria’s vineyards positions it clearly as the most extensively planted red grape variety in the country.
