The Zagros Mountains, which separate modern day Iran from Armenia, Iraq and Turkey, is home to many wild species of grapevines in the Vitis family. While wild vines are distinguished by separate male and female vines, the potential for pollination and the production of grapes could have easily happened, providing the inhabitants access to grapes. Several archaeological sites in the Zagros Mountains have uncovered similar findings as Hajji Firuz Tepe of jars containing tartaric deposits and wine residues. South of Hajji Firuz Tepe is Godin Tepe, a site that appears to have been inhabited just after the neolithic period (around 3500-3000 BC). Archaeologists there have discovered even more evidence of large scale winemaking with and wine jars as well as large basins containing wine residue, indicating that they might have been used for treading grapes as an early wine press. The residue on the jars was also found on the side of the containers, rather than the bottom, indicating that these jars were kept on their side, most likely for long term storage.
