Wachau is a prestigious wine region in Lower Austria, where steep terraced vineyards along the Danube produce concentrated, dry white wines shaped by rocky soils, warm days, and cool nighttime air. Grüner Veltliner and Riesling dominate, typically showing ripe citrus and stone fruit, firm acidity, spice, and mineral depth, with traditional styles labeled Steinfeder, Federspiel, and Smaragd according to ripeness and body.
