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 enology, “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, Malvasia Nera di Brindisi and a number of other varieties.

Malvasia wines are produced in Italy (including Lombardia, Apulia, Sicily, Lipari, and Sardinia), Slovenia, Croatia, Corsica, the Iberian Peninsula, the Canary Islands, the island of Madeira, California, Arizona, 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.
