The winery is located in the Burgenland municipality of Großhöflein on the southern slopes of the Leitha Mountains in the Leithaberg DAC region (Austria). It has been in the family since 1775. Anton Kollwentz (*1940) is the grand seigneur of Burgenland. In 1963 he pressed his first outbreak outside of Rust. From the early 1970s onwards, he earned a legendary reputation for his dry white wines. With his penchant for perfection and his openness for innovations, Anton Kollwentz became a driving force of the "Austrian red wine miracle" of the 1980ies.
His son Andi returned home to the parental winery after his education at the viticultural school in Klosterneuburg and subsequent internships in France. With the 1993 vintage, he took over responsibility in the cellar and has been managing the winery with his wife Heidi Kollwentz since 2004. The vineyards cover 23 hectares in the vineyards Steinzeiler (already mentioned in 1569), Tatschler, Dürr, Eichkogel, Gloria (with 325 m above sea level the highest site of the Leithagebirge), Haussatz, Point, Setz, and Steinmühle. They are 65% planted with the red wine varieties Zweigelt, Blaufränkisch, Cabernet Sauvignon and Pinot Noir, and 35% with the white wine varieties Chardonnay and Sauvignon Blanc.
The flagship is the red wine cuvée Steinzeiler (80% Blaufränkisch, Cabernet Sauvignon, Zweigelt) created in 1986. Other premium wines are the single-vineyard Blaufränkisch from Point and Setz, the single-vineyard Chardonnays Tatschler, Neusatz and Gloria, and the Sauvignon Blanc Steinmühle. Wines dating back to 1944 can be found in the Vinothek. Around 100,000 bottles of wine are produced annually. They also produce brandy, which is aged in barrels for 21 years. The winery is a member of the Association of Renowned Wineries Burgenland (Anton Kollwentz was the initiator and first president).
