MALMSEY, a strong sweet wine, originally made at Monemvasia (Gr. Μονεμβασία), Napoli di Malvasia, in the Morea, Greece. The name of thevplace was corrupted in Med. Lat. into malmasia, whence the English form of the word. The corruption malvasia gives the O. Fr. malvesie, from which comes the alternative English form “ malvoisie.” The wine is now made not only in Greece but also in Spain, Madeira and the Azores.
