The wine-growing region in the far north-west of Hungary on the border with Austria is named after the town of the same name (Engl. Ödenburg). It is one of the oldest in Hungary, as the Celts were already cultivating vines here. The climate, with a rather cool and rainy summer and a sunny autumn, is positively influenced by the nearby Lake Neusiedl. The vineyards on loam, loess, limestone and slate cover about 1,900 hectares of vines. The climate favours the production of red wines with the most important variety Kékfrankos (Blaufränkisch), as well as Cabernet Franc, Cabernet Sauvignon, Merlot, Kékburgundi (Pinot Noir) and Zweigelt. The white wines are made from Chardonnay, Leányka, Sauvignon Blanc and Zöld Veltelini (Grüner Veltliner). There are some joint ventures with Austrian winemakers, for example Pfneisl and Weninger Franz. Other well-known Hungarian producers are Luka Enikő, Ráspi and Szigeti.
