Archaeology could show that wine storage and making equipment was in use in many areas of the Middle East well before 4000 BC.

The oldest direct evidence for wine drinking comes from Georgia where a wine-stained shard of pottery dating to about 6000 BC has been found. The oldest winery was found in the Areni Cave in Armenia and consisted of a press, fermentation tanks and storage jars that dated to 4100 BC.
