Traces of 6,000-year-old wine discovered in Sicilian cave

Residue in terracotta jars suggests drink was being made and consumed on the island in the fourth millennium BC

Researchers have discovered traces of what could be the world's oldest wine at the bottom of terracotta jars in a cave in Sicily, showing that the fermented drink was being made and consumed in Italy more than 6,000 years ago.

Previously scientists had believed winemaking developed in Italy around 1200 BC, but the find by a team from the University of South Florida pushes that date back by at least three millennia.
