Wine tradition in Calabria was established by Greeks, that introduce new grape varieties in this region and teach to its inhabitants wine-making techniques. In a few decades the wines produced in the colony were considered better than the greek ones, and the region was later called Enotria, Land of Wine. Cirò, a wine produced in the red, white and rosé type with the same name, is believed to be the oldest wine produced in the world. Nowadays Cirò is still the major DOC produced in the region both for quantity and quality. Greco is the most used grape variety in Calabria, along with Trebbiano and Malvasia Bianca.
