Archaeologists in Spain have discovered the world's oldest known liquid wine in an unexpected place: mixed with ashes inside a Roman-era funerary urn, a new study finds.
"It's a sunken tomb that was excavated from the rock, which allowed it to remain standing for 2,000 years," José Rafael Ruiz Arrebola, an organic chemist at the University of Córdoba and a senior author of the study, told The Guardian. Using analytical techniques including high-performance liquid chromatography and mass spectrometry, the scientists sifted through element-by-element to find components that belonged to the liquid.
From looking at historical texts, they suspected that the wine would have been similar to modern fino wines produced from regions in southern Spain. The scientists compared the polyphenol content of the ancient wine to today's wines to determine that the wine was likely from Doña Mencía, a city in southern Cordoba.
