The first evidence of vinification in Greece was discovered in Philippi, eastern Macedonia. Archaeological excavations at the Dikili Tash prehistoric settlement site commenced in 1961 by the Athens Archaeological Society in collaboration with the École française d΄Athènes. Recent finds were carbon-dated by means of the C-14 method and were found to date back to the middle of the 5th millennium BC (4500 BC). The finds included charred grape pips and compressed (trodden) grape skins from wild and cultivated grapes, both an indication of winegrowing as well as evidence of winemaking activity which, at least in Europe, is considered to be the oldest.
