The winery is located in the municipality of Gols (Obere Hauptstraße 38) in the Burgenland wine-growing region of Neusiedlersee (Austria). The origins lie in the Gsellmann & Gsellmann winery, which existed until 2005. Then it was separated into the two wineries Gsellmann Matthias and the winery now run by Andreas Gsellmann. The vineyards cover 19 hectares of vineyards in Gols and Weiden in the Altenberg, Gabarinza, Goldberg, Rosenberg, Salzberg, Spiegel and Ungerberg vineyards. Three quarters of the vineyards are planted with the red wine varieties Zweigelt (main variety with 35%), Blaufränkisch, St. Laurent and Merlot, and one quarter with the white wine varieties Pinot Blanc, Neuburger, Chardonnay, Pinot Gris, Traminer, Welschriesling and Mischsatz. Biodynamic cultivation is carried out according to the guidelines of the Bioverein Respekt. In 2007, the conversion to biodynamic viticulture took place according to the guidelines of the organic association respekt-BIODYN.
The labels symbolise the central concerns of the winegrower. They show an open hand with the lettering Gols, as well as a hand pointing to this origin. The wines are fermented spontaneously with the vineyard's own yeasts. The premium white wines are aged for a long time on the fine le es in stainless steel. The mash-fermented wines are bottled without filtration. The premium red wines undergo temperature-controlled maceration with up to four weeks of maceration. They are aged for 12 to 18 months in 500-litre and large wooden barrels and bottled in Burgundy without filtration. The premium wines include the red wines Pannobile Rot (Zweigelt, Blaufränkisch), Gabarinza (Zweigelt, Blaufränkisch, Merlot) and Zweigelt Exempel, as well as the white wines Neuburger Exempel, Chardonnay Exempel and Pannobile Weiß. In years with suitable weather conditions, Beerenauslese and Trockenbeerenauslese wines are also produced. Grape juice and verjus are also produced. The winery is a member of the Pannobile and respekt-BIODYN associations.
