D’Ora wines are made at Winegut Diem, a winery that goes back to the 15th century. The Diem family took over the winery in 1848 and have been continuously producing wine since then and have earned a reputation as one of the leading producers in Austria. in 200, Gerald Diem, the fifth generation of this family to do so, took over the family vineyard production. After graduating from the Business Academy in Retz, he has studied wine management in Krems/Wachau valley. Winemaking has been his passion for as long as he can remember. He spent six months studying the vintagers art at Chateau Haut Chatain, la Lande de Pomerol in Bordeaux to deepen his knowledge of the planting care and technique of wine making. In 1998 he married Andrea, a native of Retz. New to the subject of Ontology, she has since become a passionate vintner and is now responsible for the distribution and marketing of the winery.

The grapes come from the Ried Nusberg in Obermarkerdorf in the western Weinviertel. The vineyard is located at the foot of the Manharsberg, an offshoot of the Bohemian Mass. The soil constist of sediments of sands, clays and marls as well as the remains of a Tertiary sea, which once covered large parts of the region. Vineyard has been certified organic since 2015.
