The winery is best known for its authentic red wines made from the traditional local varieties Blaufränkisch, Sankt Laurent and Zweigelt. Josef Umathum also presses fascinating white wines, such as the Pinot gris, the yellow & red Traminer and a very unusual Rosé Saignée, which has written wine history. The revival of the historical grape variety Lindenblättriger in Burgenland also goes back to Umathum. The original of the red wine cuvée "Haideboden" was pressed in this house in 1991. The best site wines come from Kirschgarten, Vom Stein and Ried Hallebühl. Only hand-picked grapes are processed and aged in traditional wooden barrels. Living soil and alert plants form the basis for the quality of the characterful wines. All works follow the rhythms of nature. In order to preserve the memory of the plants, the vines are only selected from the very oldest vineyards. The winery works in manageable structures, according to biological guidelines that are based on the philosophy of Rudolf Steiner. The goal is to bring ripe and healthy grapes intact to the cellar, so there are only hand-picked grapes. The cellar work is gentle and the expansion takes place mainly in wooden barrels. The high-quality vineyard wines are only sold at the winery after more than three years of storage. Start-up help is also offered with unusual funding campaigns for young talents from the agricultural sector. All those previously funded, such as the vegetable producer Erich Stekovics or the winemaker Uwe Schiefer, were still unknown at the time and are now fixtures in their field.
