The black turban, a child of the trollinger, came to us from the Staufer Lombardy as early as the Middle Ages. The actual origin can be derived from the name. “Urban” but also “Vernatsch”; Synonym of the trollinger, correlate with the two neighboring places "Vrban" and "Vernaz" in Croatia. These names can be used to derive peoples and their migrations, which also brings you back to the very famous Shirvan wine region. It was located in what is now Azerbaijan and northwestern Iran. It is home to a number of rediscovered grape varieties. (https://historische-rebsorten.de/rebsorte/schwarzurban/)
