The winery is located in the municipality of Leutschach-Pössnitz in the Styrian wine-growing region of Southern Styria. The basis for the quality winery was laid by Roland Tscheppe and was last managed by the brothers Eduard and Stefan Tscheppe. In 2002 the brothers Erich and Walter Polz bought the estate and the vineyards, but the management remained with the Tscheppe brothers. In the next three years, major investments were made in the area of winemaking and in the presentation and sales area. At that time the winery or rather the wine line was called "VIN'O Tscheppe". After the retirement of the managing director Eduard Tscheppe at the end of 2005, Erich and Walter Polz also took over the operative management. The "Weinhotel Gut Pössnitzberg" with 40 rooms as well as the associated inn "Kreuzwirt" is attached.
The vineyards comprise 30 hectares of vineyards in the two sites Czamillonberg (10 hectares) and Pössnitzberg (Römerstein). They are 90% planted with the white wine varieties Sauvignon Blanc, Morillon or Chardonnay, Gelber Muskateller and Gewürztraminer, and 10% with the red wine varieties Cabernet Sauvignon, Zweigelt and St. Laurent. The wines are produced in two lines. For the fruity and varietal typical "classic wines", mainly grapes from the Pössnitzberger Römerstein are used. The grapes from the Czamillonberg are used to produce powerful site wines, some of which mature in . In the 2017 vintage 410,000 bottles were produced. Wines can be purchased back to the 1949 vintage.
