Early in the morning antiquity knew that Assyrian. Egyptian and Greeks the cork. In part, cork stoppers were also used as a closure for vessels like amphorae used. Mostly, however, pots made of terracotta (clay) were in use, which were attached with string and then sealed with paint, clay or pitch. The Roman author Cato the Elder (234-149 BC) writes that the wine jugs after the fermentation would have to be closed with cork and pitch. The Romans already knew this type of closure, but it was forgotten with the fall of the Roman Empire. This was probably because the Iberian Peninsula, the main source of cork bark, was conquered by the Moors in the 8th century and ruled for a long time. Until the late Middle Ages vessels were sealed with oil-immersed and hemp-wrapped wooden plugs, pitch or wax.
