Various glass containers for liquids were already being produced in ancient Egypt as early as 1,500 BC. But it was not until the invention of the glassmaker's pipe (and thus glassblowing) in the 2nd century BC by the Phoenicians in the area of Syria that the Romans were able to produce glass bottles on a larger scale from the beginning of our era. The oldest wine bottle in the world is on display in a museum in Speyer. It was found in a Roman grave and dates from the 4th century AD. However, due to the fragility of glass, vessels made of clay or earthenware and wooden barrels were still mainly used for transport and storage until the 17th century. Furthermore, wine was not marketed in small containers at that time, but almost exclusively in large containers (mainly wooden barrels).
