Andi Kollwentz has managed the winery since 2004. His father Anton Kollwentz is at his side. Anton, the pioneer of Burgenland, draws from a wealth of experience from 50 years of wine growing. In addition to the meticulous viticultural work, the success of the Kollwentz family is probably due to their vineyard ownership. The vineyard sites on the southern slopes of the Leithagebirge such as Steinzeiler, Point, Dürr, Tatschler, Katterstein, Gloria and Setz are numbered among the finest and most venerable in the land. Red varieties are primarily planted from 170m to 200m above sea level, while Chardonnay's realm starts above 200m. The altitude and the influence by the woods that cover the highest elevations of the Leithagebirge give rise to a cool microclimate. On those sites, the grapes will slowly mature to full ripeness, which is reflected in their refined aromas and the intensive taste.
