(Thelocal) - Scientists want to study samples of the world’s oldest wine, currently on display at the Historical Museum of the Palatinate in the western German city of Speyer. There’s just one problem: everyone’s afraid to open the bottle. The glass bottle, thought to be at least 1,650 years old, was found in a Roman grave near Speyer in 1867 and put on display at the museum. Since then, it’s been handled extremely carefully, and been on display in the exact same spot in the museum for 100 years.
