Ausbruch (literal meaning: "break-out") or sometimes Ausbruchwein is an Austrian wine term for a quality level in the Prädikatswein category.
[1] It is situated between Beerenauslese and Trockenbeerenauslese in requirements, which makes it a sweet dessert wine typically made from grapes affected by noble rot.
The category was introduced into Austrian wine legislation in 1970, as a legalization of the production method allegedly already used in the area of Rust.
This filled the purpose of dissolving crystallized sugars in the grapes in order to speed up the fermentation and make it more efficient.
[1][2] Historically the Hungarian grape Furmint was used in Ausbruch production but today it is rarely found in Austria.
