What is the oldest known bottle of wine?

The Speyer wine bottle holds wine and was originally found in 1867. It was found in what is now the Rhineland-Palatinate region of Germany, near the town of Speyer (one of the oldest settlements in the area). The artifact has since become known as "the world's oldest existing bottle of wine". The bottle has been dated between 325 and 350 AD, and is the oldest known unopened bottle of wine in the world. Since its discovery, it has been exhibited at the Wine Museum section of the Historical Museum of the Palatinate in Speyer. It is always displayed in the same location within the museum. The "Römerwein" is housed in the museum's Tower Room. It is a 1.5-litre (51 US fl oz.) glass vessel with amphora-like "shoulders," yellow-green in color, with dolphin-shaped handles.
