Weingut Emmerich Knoll
Weingut Emmerich Knoll is one of Austria's most well-known wine producers. The Knoll estate is located in the Wachau region, in the village of Unterloiben. It was established in 1825 and is still family-owned and -operated. Knoll is best known for its age-worthy, expressive Riesling and Grüner Veltliner wines from unique sites on the northern bank of the Danube.
The estate covers 14 hectares (35 acres) on highly regarded sites including the Schütt, Loibenberg, Kellerberg, Kreutles and Pfaffenberg vineyards. These sites are planted to 45 percent Riesling and 45 percent Grüner Veltliner, with the remainder planted to Chardonnay, Yellow Muscat, Rivaner, Blauer Burgunder and Gelber Traminer. Soil types vary from site to site but are primarily composed of loess, loam, granite, and gneiss top soils.
Emmerich Knoll is a member of the Vinea Wachau Nobilis Districtus and follows the association's strict quality control regulations and three tier system, producing Steinfeder, Federspiel and Smaragd level wines. Some of the estate's top wines include the Kellerberg Riesling Smaragd, Loibenberg Grüner Veltliner Smaragd, and Beerenauslese and Trockenbeerenauslese wines that are made only in vintages conductive to the development of botrytis.
The estate handpicks the grapes at specific ripeness and must weights, blocks malolactic fermentation for freshness, and uses large oak fourdres almost exclusively for an oxidative winemaking process.
