With nearly 30 centuries of wine making and responsible for spreading vines across much of the Mediterranean, it goes without saying that Greece is steeped in viticultural history. Given that most grapes grown today go into making raisins and table grapes and that production normally on a very small traditional scale, wine is a relatively small part of the agricultural sector. That said, vineyards are planted in all parts of the country from as far south as the island Crete all the way to the most northern limits of the country in regions such as Goumenissa. The countries specialty is Retsina; before glass or oak barrels were used, earthenware was the favored material for making vessels, however given how porous it can be the Amphorae's were lined with resin to become air tight. The result was a wine with a distinct and desirable flavor. Today Retsina wine is replicated by adding small pieces of pine resin to the fermenting must until the first racking separates wine from all solids. The Muscat of Sámos is probably the country's second most favorite wine. Grown on high elevations on terraces plots on the islands steepest hillsides it appears in three distinct styles; Sámos Doux, a vin de liqueur, Sámos Vin Doux Naturel, and Sámos Nectar, made from dried in the sun.
