The Weinviertel is by far the largest wine-growing region in Austria. It covers a total of about 17000 hectares of vineyards and thus almost one third of the total area of Austria. The Weinviertel is not necessarily a homogenous area. It is bordered in the southwest by the wine-growing regions of Kamptal and Wagram and in the south by the Danube. It extends in the north along the Czech border and in the east along the Slovak border around Wien and ends again shortly before the wine-growing region of Carnuntum on the Danube. The vineyards are widely scattered throughout the area and have distinctly different soil types. The climate is predominantly continental, but a Pannonian influence is already noticeable in the far east. In addition, there is a small climatic island near Haugsdorf and Mailberg, which is considered particularly suitable for the cultivation of red varieties due to its very warm and dry conditions.
