The Speyer wine bottle most likely holds wine, and was originally found in 1867, in what is now the Rhineland-Palatinate region of Germany near 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, always displayed in the same location within the museum. The "Römerwein" is housed in the museum's Tower Room. It is a glass vessel with amphora-like "shoulders," yellow-green in color, with dolphin-shaped handles.
Discovery
The bottle was discovered during an excavation in a 4th-century AD Roman nobleman's tomb. The tomb contained two sarcophagi, one holding the body of a man and one a woman. One source says the man was a Roman legionary and the wine was a provision for his celestial journey. Of the six glass bottles in the woman's sarcophagus and the ten vessels in the man's sarcophagus, only one still contained a liquid. There is a clear liquid in the bottom third, and a mixture similar to rosin above.
Wine preservation
While it reportedly lost its ethanol content, analysis is consistent with at least part of the liquid having been wine. The wine was diluted with a mixture of herbs. The preservation of the wine is attributed to the large amount of thick olive oil, added to the bottle to seal the wine off from air, along with a hot wax seal. Petronius, in his work, Satyricon, writes of plaster sealed bottles, and this one is analogous. The use of glass in the bottle is unusual, however, as typically Roman glass was too fragile to be dependable over time. While scientists have considered accessing the liquid to further analyze the content, as of 2018 the bottle remained unopened, because of concerns about how the liquid would react when exposed to air. The museum's curator, Ludger Tekampe, has stated he has seen no variation in the bottle in the last 25 years.
