The world's oldest bottle of wine, dated 325-359 AD, has been found and studied by archaeologists. A 1,5-liter wine bottle was found in the tomb of a noble Roman couple near the city of Speyer in Germany.
The ancient wine has remained sealed in the bottle for almost 1700 years, experts have noted, but despite this, it is probably still drinkable. The drink was made from a mixture of local grapes, herbs and olive oil. Now the wine looks very unattractive and has lost all the ethanol. The bottle has not yet been opened and scientists argue about the need for this.
So, historians argue that the bottle should be kept closed so as not to miraculously damage the preserved drink, and microbiologists insist that opening the bottle can be dangerous.
