The Knoll winery is located in the Unterloiben wine-growing community in the Lower Austrian Wachau wine region. It has been run by the Knoll family for several generations. Today Emmerich and his wife Monika run the business. For decades, the winery has consistently been one of the absolute top wine addresses in Austria. The vineyards cover 15 hectares and are located in the famous Wachau vineyards of Kellerberg, Kreutles, Loibenberg and Schütt, as well as Pfaffenberg in the adjacent Kremstal wine region. Wines from Pfaffenberg may of course not be called Vinea Wachau (Federspiel, Steinfeder, Smaragd). The vineyards are planted 45% each with the main varieties Grüner Veltliner and Riesling, the rest is divided between Gelber Muskateller, Gelber Traminer, Chardonnay and Blauburgunder(Pinot Noir).
The bottle labels have been decorated for decades by Saint Urban, the patron saint of winegrowers. The vinification of the wines is based on tradition and consistency. A wide range of almost 30 wines is produced, nine each of Riesling and Veltliner. The flagships of the house are Grüner Veltliner Schütt Smaragd, Grüner Veltliner Vinothek filling, Riesling Schütt Smaragd and Riesling Vinothek filling. A speciality produced only in years with appropriate conditions are sweet high-premium wines such as Auslese, Beerenauslese and Trockenbeerenauslese. Knoll wines have great storage potential. About 150,000 bottles are produced annually. The winery is a member of the Vinea Wachau Nobilis Districtus association. The restaurant "Loibnerhof" adjacent to the winery is run by cousin Josef Knoll.
