Oldest Unopened Wine
The world's oldest unopened bottle of wine has been sealed since the 4th century. The Speyer wine bottle is 1.5-liters. Discovered in a Roman nobleman's burial in what is current Germany, the drink dates back to the years between 325 and 359 AD (about 1,650 years old). No one knows how it would react to the air if opened, but it would probably taste pretty gross.
