Ruster Ausbruch is a sweet wine made from botrytized grapes in the town of Rust on the Neusiedlersee in Burgenland, Austria. Ausbruch is the German-language equivalent of Aszú, the term used in neighbouring Hungary for sweet wines made from white and red grapes affected by noble rot, such as Welschriesling, Muskateller, Sauvignon Blanc, Pinot Blanc, Pinot Noir and Chardonnay, and Furmint. Both Tokaji and Ausbruch were probably developed at a similar time in the early 17th century, by adding small percentages of non-botrytized grapes to the juice of mainly Furmint grapes concentrated by noble rot, due to warm and moist air from the nearby shallow lake warmed by air off the Pannonian plain (the Carpathian Basin).
