Wachau (wine)

Wachau is one of Austria's most established and notable wine regions, specializing in dry wines made from Riesling and Grüner Veltliner. Located in Lower Austria along the Danube, west of Vienna and Krems an der Donau, it is one of the western most wine producing regions in Austria with only a few scattered plantings in Tyrol being further west. While most of Austria follows a wine classification systems based on ripeness and harvest must weight that parallels the German wine classification system, Wachau wines have a unique classification system. The three classification levels for Wachau wine include Steinfeder for wines up to 11.5% alcohol level, Federspiel for wines between 11.5–12.5% and Smaragd that must have a minimum of 12.5% alcohol level. Despite its renown, the Wachau is a small wine region that usually accounts for only around 3% of Austria's wine production.

Archeological evidence suggests that viticulture may have been introduced to the lands around the Danube by the Celtic tribes, most notably the La Tène and Noricum federation, prior to the Roman influence that came into the area following conquest around the 1st century BCE. Viticulture continued to flourish under Roman rule, with the introduction of Roman technology and knowledge, even though grape growing was technically banned in Roman territories north of the Alps. In the 3rd century, Emperor Marcus Aurelius Probus officially overturned the ban and is reported to have ordered the introduction of several grape varieties to be brought into the territories. It has been speculated that both Grüner Veltliner and Welschriesling may have been introduced to the region during the Roman period.
