The story of retsina wine can be traced back to ancient times, when wine was typically stored and transported in clay jugs called amphorae. In Greece, one of the world’s oldest winemaking civilizations, winemakers used thick resin from the abundantly-growing Aleppo pine trees to seal the amphorae and protect the wine from oxidation. Evidence of pine resin has been found in Greek wine amphorae dating back to the 13th century B.C.
