Reddish-brown liquid found in untouched 2,000-year-old Roman tomb is a local, sherry-like wine
The oldest wine ever to have been discovered in its original liquid form is reddish-brown and, quite conceivably, full-bodied. Reddish-brown because of the chemical reactions that have taken place in the 2,000 years since the white wine was poured into a funeral urn in southern Spain – and potentially full-bodied because the urn also contained, among other things, the cremated bones of a Roman man.
Analysis by experts at the University of Córdoba has established that the ancient tawny liquid inside the urn – which was found in a rare, untouched Roman tomb that was accidentally discovered in the Andalucían town of Carmona five years ago – is a local, sherry-like wine.
Prior to the discovery, which is reported in the Journal of Archaeological Science: Reports, the oldest wine preserved in a liquid state was the Speyer wine bottle, which was excavated from a Roman tomb near the German city of Speyer in 1867 and dated to about AD 325.
The Spanish urn was recovered in 2019 after a family having some work done on their house in Carmona stumbled across a sunken tomb on their property.
I am a historian whose specialty is too recent to deal with anything like that (20th century), but also have a friend who, to be generic here, deals with a handful of a few centuries back. She found a baggie of a drug mistakenly stored with a letter in an archive (think 18th century) and on a whim, dipped their pinky into the powder and tried it. They regret that decision, but also, nothing happened:)
EDIT: Historians can be boring, but not always that tame
