The winery is located in the cadastral district of Stammersdorf in the 21st district of Floridsdorf in the north of the Austrian capital Wien. The winery, which is rich in tradition and around 100 years old, was run purely as a wine tavern until the 1980s, when Fritz Wieninger Jr. took over the management of wine production. In 2005, a new production building was put into operation in a historic building. The vineyards cover 40 hectares; the vineyards are located on the slopes of the Bisamberg in the south and south-east of the Großlage in the vineyards Breiten, Gabrissen, Herrenholz, Jungenberg, Rothen and Wiesthalen, mainly on sandy, loamy and lime-rich loess soils.
On the Nußberg on the other side of the Danube, 15 hectares of vineyards are leased, including the Preußen and Rosengartel vineyards. Two thirds of the vineyards are planted with the white wine varieties Grüner Veltliner, Pinot Blanc, Pinot Gris, Chardonnay, Sauvignon Blanc, Riesling, Gelber Muskateller and Traminer, and the red wine varieties Zweigelt, Pinot Noir, Cabernet Sauvignon and Merlot. In 2014, the Viennese winery Hajszan-Neumann with 20 hectares of vineyards was taken over; however, the brand name is retained. Since 2006, certified biodynamic viticulture has been practised according to the rules of the respekt-BIODYN association. Pesticides (such as herbicides), systemic sprays and artificial fertilisers are completely avoided. Instead, infusions and biodynamic preparations are used. Flora and fauna are supported by a sophisticated cover crop of the vineyards. The focus is not on high yields, but on health, self-healing power and the quality of the vines and the wine.
The white wine grapes are destemmed (de-stemmed) and gently pressed, depending on the grape variety or the desired wine type. The must is then fermented in temperature-controlled steel tanks, wooden barrels of various sizes and partly in barriques. The red wines are classically fermented on the skins either in closed tanks or, as in the case of Pinot Noir, in open vats made of oak. They always undergo malolactic fermentation and are then aged exclusively in barriques. The top line is called "Grand Select", which is bottled without filtration. The flagship of the house is the "Pinot Grand Select" produced in Burgundy style from heavily yield-reduced areas.
Other premium wines are the barrique-aged "Chardonnay Grand Select", "Grüner Veltliner Kaasgraben", the red wine cuvée "Wiener Trilogie" (Zweigelt, Cabernet Sauvignon, Merlot) and the Wiener Gemischter Satz DAC, which is especially cultivated by the winery and vinified in the categories "classic" and with the site designations "Bisamberg", "Nußberg" and "Rosengartl". Around 350,000 bottles of wine are produced annually. About one third is exported to about 60 countries with Germany and the USA as the most important customers. Sparkling wine and grape juice are also produced. The winery is a member of the associations Premium Estates of Austria, Tu Felix Austria, WienWein and Traditionsweingüter Österreich.
