Austrian wines are mostly dry white wines (often made from the Grüner Veltliner grape), though some sweeter white wines such as dessert wines are made around the Neusiedler. About 30% of the wines are red, made from Blaufränkisch (also known as Lemberger, or as Kékfrankos in neighbouring Hungary), Pinot noir and locally bred varieties such as Zweigelt. Austria has a rich history of winemaking that goes all the way back to 4000 years. The country is also home to Riedel, makers of some of the most expensive wine glasses in the world.
