According to Homer writings, the wines of Cephalonia were known since ancient times, consisting the most appreciable gift, able to hold friendships, create new bounds, dispel misunderstandings, build alliances. Nowadays 2/3 of the vineyards of Cephalonia are located in mountainous or semi-mountainous areas, mainly on limestone ground particularly poor in organic material. The island's climate is mild, quite rainy and the mount Enos (“Black mountain”) offers extremely favorable conditions. All of the above, in combination with the low yield per acre and the small size of the vineyard plots (averaging 4.5 acres per grower), have defined the viniculture type. The variety mostly cultivated is Robola and secondarily the white Muscat, Mavrodaphne,Tsaousi, Vostilidi or Goustolidi, Zakynthino and fragrant Moschatella which is the islands exclusivity. The above varieties produce 3 Protected Geographical Indication (P.G.I.) wines: Slopes of Enos, Metaxata, Mantzavinata and 2 Protected Designation of Origin (P.D.O.): sweet Mavrodaphne of Cephalonia and white Muscat of Cephalonia. The top wine of the island is PDO Robola of Cephalonia. This famous variety is, mainly, cultivated in the southern and central part of the island, on a 3,000 acre vineyard stretching, reaching a height of 800 meter heights. The plants are planted literally on stone, hence the name Vino di Sasso (wine of stone) given by the Venetians to Robola.
