The Kollwentz family vineyards in Grosshöflein, Burgenland, cover 25 hectares. The vineyards are located on the southern slope of the Leithagebirge and range from 170 m to 325 m above sea level, making them among the oldest and most exciting in the country.

The warmest sites are dominated by Blaufränkisch. The Point and Setz vineyards form the core of the Grosshöflein red vineyards, from which the Blaufränkisch for "Steinzeiler" – the winery's top red wine – originates.

Above 200 m, the realm of the Chardonnay grape begins. The altitude and the influence of the adjacent forests create a cool microclimate, which is reflected in the finesse of the aromas and the intensity of the taste. The Chardonnay vineyards Gloria, Tatschler, Katterstein, and Neusatz are dominated by limestone soils, as is Ried Dürr, planted with Pinot Noir.

Andi Kollwentz is a versatile winemaker among Austrian producers, as he knows how to handle a wide variety of grapes, and his wines – white, red, or sweet – are always at the top.
