The Leo Alzinger winery is located in the municipality of Unterloiben in the Lower Austrian wine growing region of Wachau. It is managed by Leo Alzinger sen. (born 1946) and Leo Alzinger jr. (born 1979). Leo junior, trained at the HBLA Klosterneuburg, with practical experience in Austrian companies, Germany and New Zealand, integrates his own ideas and continues with the same consistency what his father started - "all or nothing". The vineyards comprise nine hectares of vines in the Wachau top vineyards Burgstall, Frauenweingarten, Höhereck, Hollerin, Liebenberg, Loibenberg, Mühlpoint and Steinertal. They are 100% planted with white wine varieties, namely Grüner Veltliner (55%), Riesling (40%) and Chardonnay (5%). The best wines are developed in a location-oriented way, which is documented by the guiding principle of the house: "We let each location have its own personality". Among the premium wines are for example Riesling Smaragd Dürnsteiner Höhereck, Grüner Veltliner Smaragd Reserve (bottled only in Magnums), Grüner Veltliner Smaragd Mühlpoint and Grüner Veltliner Smaragd Loibner Steinertal. The winery is a member of the Vinea Wachau Nobilis Districtus wine growers' association.
