Malvasia (, also known as Malvazia) is a group of wine grape varieties grown historically in the Mediterranean region, Balearic Islands, Canary Islands and the island of Madeira, but now grown in many of the winemaking regions of the world. In the past, the names Malvasia, Malvazia, and Malmsey have been used interchangeably for Malvasia-based wines; however, in modern oenology, "Malmsey" is now used almost exclusively for a sweet variety of Madeira wine made from the Malvasia grape. Grape varieties in this family include Malvasia bianca, Malvasia di Schierano, Malvasia negra, , Malvasia nera di Brindisi, Malvasia di Candia aromatica, Malvasia odorosissima, and a number of other varieties. Malvasia wines are produced in Greece (regions of Peloponnese, Cyclades and Crete), Italy (including Friuli-Venezia Giulia, Lombardia, Apulia, Sicily, Lipari, Emilia-Romagna, and Sardinia), Slovenia, Croatia (including Istria), Corsica, the Iberian Peninsula, the Canary Islands, the island of Madeira, California, Arizona, New Mexico, Australia and Brazil. These grapes are used to produce white (and more rarely red) table wines, dessert wines, and fortified wines of the same name, or are sometimes used as part of a blend of grapes, such as in Vin Santo. History Most ampelographers believe that the Malvasia family of grapes are of ancient origin, most likely originating in Crete, Greece. The name "Malvasia" comes from the Italian name for Monemvasia, a medieval and early Renaissance Byzantine fortress on the coast of Laconia; the town's port acted as a trading center for wine produced in the eastern Peloponnese and perhaps in some of the Cyclades. During the Middle Ages, the Venetians became so prolific in the trading of Malvasia wine that merchant wine-shops in Venice were known as malvasie. The occasional claim that the name might come from the district of Malevizi, near Iraklion, Crete, is not taken seriously by scholars. Malmsey was one of the three major wines exported from Greece in medieval times. (For other examples, see Rumney wine and Cretan wine). It is alleged that when Edward IV of England convicted his brother, George Plantagenet, 1st Duke of Clarence, of high treason, his private execution (1478) consisted of being "drowned in a butt of Malmsey wine", as dramatized in Shakespeare's Richard III. Both Monemvasia and Candia have lent their names to modern grape varieties. In Greece there is a variety known as Monemvasia, evidently named after the port, though now grown primarily in the Cyclades. In western
