The winery is located in the municipality of Fels am Wagram in the Lower Austrian wine-growing region of
Wagram. It was founded in 1964 by Horst and Marianne Kolkmann. Today it is run by the third generation, Horst and Gerhard Kolkmann, and Dipl.-Ing. Sebastian Blümig is responsible for the cellar technology. The vineyards cover 35 hectares in the Brunnthal, Diebstein, Essenthal, Fumberg, Welfel and Zeisleiten vineyards. They are 60% planted with the white wine varieties Grüner Veltliner, Riesling, Sauvignon Blanc, Pinot Blanc, Chardonnay, Rivaner, Roter Veltliner, Frühroter Veltliner, Gelber Muskateller and Sämling 88, and 40% with the red wine varieties Zweigelt, Blauburgunder, Blauer Portugieser, St. Laurent and Cabernet Sauvignon.
The vineyards are cultivated according to the principles of
organic viticulture. This includes year-round
cover crop and no chemical
fertilisers. The wines are vinified according to their
origin and
variety. The white wines are matured at a controlled temperature in stainless steel, a Roter Veltliner speciality in 500-litre oak barrels. The red wines mature in barriques. Special attention is paid to Grüner Veltliner with different varieties. The premium wines include the Grüner Veltliner "Brunnthal" and "Lössmann", as well as the red wine Zweigelt Reserve. In years with suitable weather conditions, an
ice wine is also produced. Red wine liqueur, rosé secco (sparkling wine),
vinegar and noble brandy (pear, apricot) are also produced. The winery is a member of the
Wagramer Selektion winegrowers' association (whose chairman was Horst Kolkmann until 2005)
