Welcome to Greece
Resin and Greek wines are synonymous. Pine resin has been used in Greek wine production since the time of the ancient Greeks. The theory is that resin adds an improvement to the taste of the wine when added during fermentation. People have gotten used to the taste and half of the wines produced in Greece use resin.
Other wines to note are mavrodaphne, a sweet dark wine similar to an Italian recioto and nemea. Until Greek wine producers adopt strict viticultural and vinicultural practices, Greek wines will remain on the periphery of serious wines.
