The estate is located in the Oggau municipality in the Burgenland DAC area Leithaberg (Austria). It has been family-owned since 1632. Son-in-law Christian trader and his nephew Tobias Siess manage vineyards and cellars. Rafaela, his wife, leads the office. Son-in-law Matthias Siess and his son Sebastian are responsible for sales and marketing. His wife Maria runs the manor inn "Zum Herztröpferl". The vineyards cover 33 hectares of vineyards in the vineyards Altenberg Haide Isel Marienthal, Neugebirge, Pratsche, set of Zeisl and Steinhut. They are 75% with the red varieties Blaufränkisch , Zweigelt, St. Laurent, Cabernet Sauvignon, Cabernet Franc and Merlot, and 25% with the white varieties Welschriesling, Pinot Blanc, Chardonnay and more. Sauvignon Blanc planted.
Consistently natural, environmentally friendly viticulture is practiced. Quality criteria in the vineyard are short pruning and thin out to reduce yield. The goal is wines that are typical of the variety, region and vintage. The wines are vinified in the three lines Classic (stainless steel, young bottled), Premium (wooden cask, classic) and the top line Large layers (aged in barriques). Top wines are Blaufränkisch Marienthal, Tempelhüter (Zweigelt), and the red wine cuvée Furioso ( Blaufränkisch , Cabernet Sauvignon, Cabernet Franc, Merlot). In weather-appropriate years, noble sweet wines are also pressed. Around 100,000 bottles of wine are produced annually. Fine brandies (wine, cherry) and bottle-fermented sparkling wines are also produced.
The MAD winery and the imperial city of Bad Ischl are dedicated to His Majesty Emperor Franz Josef I (1830-1916). In honor of the former ruler, two wines were created, namely a red wine ( Blaufränkisch , Merlot, Zweigelt) and a white wine (Grüner Veltliner, Chardonnay), which are marketed specifically in Bad Ischl. "Kaiser" Franz Klammer (Austrian ski racer and Olympic downhill champion 1976) took over the sponsorship. The “Franz Klammer Foundation” is supported with part of the proceeds from each bottle of wine sold. The money goes to athletes who need help because of their injuries and disabilities.
