The winery above the municipality of Maierhofen is located near Fürstenfeld in the wine-growing region Vulkanland Steiermark
(Austria). The castle, newly built according to old models, was opened in 2006. It includes a wine culture site with the motto "stage for art, culture and wine". It is also a hostel of the European Knighthood of Wine to which Koarl Thaller belongs. A Buschenschank is connected. The company is run by “Koarl” (Karl) and Maria Thaller, already actively supported by their children. The career changer Koarl Thaller graduated from the viticulture school Silberberg
and passed the master examination in viticulture and cellar management. The Styrian red wine pioneer first produced a Shiraz in Styria in 1993.
The vineyards cover 20 hectares of vineyards in the Jullerltal, Marienberg, Steinfeld and Rosengarten vineyards. They are (surprisingly by Styrian standards) 80% planted with the red varieties Zweigelt, Blauburgunder, Cabernet Sauvignon, Merlot, St. Laurent and Shiraz, and 20% with the white varieties Welschriesling, Pinot Blanc, Chardonnay, Gelber Muskateller and Sauvignon Blanc. Premium wines are the two red wine cuvées "Rochus" (Pinot Noir, Zweigelt, Merlot, Cabernet Sauvignon) and "Moarhof" (Zweigelt, Cabernet Sauvignon), as well as the white wines Welschriesling and Herrnberg Classic. Castle actor Peter Simonischek presented the red wine blend "Mythos" in 2010. The winery publishes the in-house newspaper "Thallers Bottle Mail".
