Archeologists in Italy have set about making red wine exactly as the ancient Romans did, to see what it tastes like.

Based at the University of Catania in Sicily and supported by Italy's national research centre, a team has planted a vineyard near Catania using techniques copied from ancient texts and expects its first vintage within four years.

"We are more used to archeological digs but wanted to make society more aware of our work, otherwise we risk being seen as extraterrestrials," said archaeologist Daniele Malfitana.

At the group's vineyard, which should produce 70 litres at the first harvest, modern chemicals will be banned and vines will be planted using wooden Roman tools and will be fastened with canes and broom, as the Romans did.
