Bavarian monasteries cut the first dry-stone terraces of this Danube gorge in the early Middle Ages, and the landscape they began — a narrow vineyard threaded between Melk and Krems, its terrace walls still maintained by hand — was inscribed by UNESCO in 2000 as a river valley shaped by a thousand years of use.
When Austrian wine had to rebuild itself after the scandal of 1985, the Wachau led the way: the codex of its growers, Vinea Wachau, adopted in 1983, defines three ascending categories of dry wine — Steinfeder, Federspiel and Smaragd, the last named for the emerald lizard that suns itself on the terrace walls — and Grüner Veltliner and Riesling grown on gneiss became emblems of the country's quality rebirth.
