Designation for wines with a high content of unfermented sugar, which are pressed from grapes rich in sugar. Optimal climatic conditions for this exist in many places around the Mediterranean, which is why many of the famous sweet wines come from Greece, Spain, France, Portugal and Italy. They have an ancient tradition. Among the most famous ancient wines are the sultana wine Passum from Rome and Commandaria from the island of Cyprus. In the late Middle Ages, sweet wines were immensely popular at the European ruling houses. The Greek port of Monemvasia was a famous transhipment point for sweet specialities from Aegean islands such as Crete, Paros, Samos and Santorini. The emerging global trade made Constantia from South Africa, sweet wines from France and Tokay from Hungary known and famous. From the 16th century onwards, expeditions to the newly discovered regions preserved wines with alcohol for the long sea voyages. This was the beginning of the triumphal procession of Madeira, Port, Sherry and Co.
