God knows, to be honest last time I drank it I was in Skiathos, a few years back, the Barman was plying us with it but asked us to be quiet about how much he was charging, as there was a party of Germans there and he was charging them double as they had apparently bombed the shit out of the place during the war.
We were there for two weeks and drank a lot, but the bottles were all in Greek and to be honest between that and the Retsina all I remember was it was lovely.
