Dr. Hans Ambrosi (1925-2012) received his doctorate in Geisenheim after the Second World War. In 1955 he went to South Africa and worked there for almost eleven years on various wineries as an agricultural engineer and consultant. In 1966 he returned to Germany and in the same year was appointed director of the Hessian State Wineries in the town of Eltville in the Rheingau. During this time he was also responsible for the famous Cistercian monastery Eberbach (one of the domains). In 1966, the first Eiswein was produced in the Rheingau on his initiative, which is why he is also known as the "Eisweinkönig". Ambrosi then retired in 1990 and devoted himself more than ever to writing. As author as well as editor of about 60 books, he is one of the most widely read wine publicists in Germany. A small selection of these: The enjoyable wine tasting (interesting facts and tips for leisurely hours), Colour Atlas of Grape Varieties (300 grape varieties and their wines), Cape Region, Rheingau pure, Learning to enjoy wine properly (introduction to wine sensory analysis), From wine lover to wine connoisseur, Wine encyclopaedia, Wine from A - Z (answers to all questions in 5000 keywords).
