The listed Grottnerhof has existed since the 13th century, already Oswald von Wolkenstein mentioned it in his texts. The historic farm was renovated and taken over by the Pramstrahler family in 2007, nuances between old tradition and modernity were created. With great success the varieties Sauvignon, Pinot Blanc, Gewürztraminer and Pinot Noir are cultivated in the newly planted vineyards. With the most modern cellar technology, the varieties are refined and finally bottled.
