Santorini is a Greek wine region located on the archipelago of Santorini in the southern Cyclades islands of Greece. Wine has been produced there since ancient times, but it was during the Middle Ages that the wine of Santorini became famous worldwide under the influence of the Republic of Venice. The Italian influence is still present in modern Santorini winemaking: the most famous Tuscan sweet wine is called Vin Santo just like Santorini's Vinsanto/Visanto (labeled such to differentiate it from the Tuscan wine). It is made in a passito style from grapes dried in the sun after harvest.
