The estate is located in the municipality Oggau in Burgenland DAC area Leithaberg (Austria). It has been family owned since 1632. Son-in-law Christian Händler 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 leads the guesthouse "Zum Herztröpferl". The vineyards cover 33 hectares of vineyards in the vineyards Altenberg, Haide, Isel, Marienthal, Neugebirge, Pratsche, Zeisl and Steinhut. They are 75% with the red varieties Blaufränkisch , Zweigelt, St. Laurent, Cabernet Sauvignon, Cabernet Franc and Merlot, as well as 25% with the white varieties Welschriesling, Pinot Blanc, Chardonnay u. Sauvignon Blanc planted.
It is practiced consistently close to nature, environmentally friendly viticulture. Quality criteria in the vineyard are short pruning and thin out for the purpose of yield reduction. The goal is varietal, area and vintage wines. The wines are vinified in the three lines Classic (stainless steel, young bottled), Premium (wooden barrel, classic) and the top line Large vineyards (matured in oak barrels). Top wines are Blaufränkisch Marienthal, Tempelhüter (Zweigelt), as well as the red wine cuvée Furioso ( Blaufränkisch , Cabernet Sauvignon, Cabernet Franc, Merlot). In weather-appropriate years also noble sweet wines are pressed. Every year around 100,000 bottles of wine are produced. There are also brandies (wine, cherry) and bottle-fermented sect produced.
The winery MAD 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. The sponsorship has been taken over by "Emperor" Franz Klammer (Austrian ski racer and Olympic champion 1976 in the downhill). The "Franz Klammer Foundation" is supported with part of the proceeds of every bottle of wine sold. The money will benefit athletes who need help because of their injuries and disabilities.
