The bottle was found a couple of years ago in an 18th-century chest owned by the Jacoli family, although it has only just been approved by experts, Rai News 24 reported.
A handwritten note found with the bottle said, “Vinegar taken from a flask from the Gregori family of Modena in 1740. Today, February 17th 1943, the vinegar is 203 years old. Signed, Giulio Jacoli fu Cesare”.
The bottle was passed on to experts at the Museum of Balsamic Vinegar in Modena, who gave the aged liquid 307 points, Rai said. This is just 10.8 points below the winner of this year’s 'best balsamic vinegar' competition.
Balsamic vinegar from Modena is one of Italy's prized products and subject to strict controls. As a result the best bottles can cost hundreds of euros.
