Johannes Holzer cultivates ten hectares of vineyards in the region's best sites. About 50 percent of his vineyards are located in the often award-winning top site Engabrunner Stein. The different soil types, from primary rock to gravel to deep loess, offer ideal conditions for high quality and great variety. In addition to the classic varieties Grüner Veltliner and Riesling, Frühroter Veltliner, Chardonnay, Sauvignon Blanc, Gelber Muskateller, Zweigelt and St. Laurent also thrive to produce very fruity and complex wines. The main variety of the winery, Grüner Veltliner, is vinified in four stages; from the Kamptal DAC from the Karl vineyard and the medium-bodied "Alte Rebe" from vines over 45 years old, to the single-vineyard wine from the premium site Engabrunner Stein and the multiple award-winning "Ganztraube vom Stein".
Quality-oriented work in the vineyard, on the basis of strictly controlled management with voluntary renunciation of insecticides and herbicides since April 2021, (his farm is also "Sustainable Austria" certified), strict grape selection by hand harvesting and gentle grape processing with state-of-the-art cellar technology have the highest priority for Johannes Holzer.
Awards such as "AWC Gold", the award to the circle of the best and the inclusion in the "SALON Austria Wine", as well as Lower Austrian state wins and AWC variety wins, but also the victory at the "Kamptal Trophy", underline the high quality of his wines.
