Archaeologists in Italy have unearthed a massive Roman villa and vineyard complex that served as an imperial wine production estate. The site features a series of subterranean dolia (massive ceramic fermentation vats) that are still intact, some still containing microscopic residue of grape seeds and resins used for preservation.
The estate also includes a grand residential wing with mosaics depicting Dionysian festivals and an advanced hydraulic system for irrigation. Experts believe this estate was a primary supplier of high-quality wine for the Roman legions stationed along the Danube frontier.
