- The champagne was discovered last year in a shipwreck off the Finnish coast.
- Other champagne found on the shipwreck are estimated to fetch up to 100,000 euros per bottle.
Champagne experts have discovered what are believed to be the oldest existing bottles of Heidsieck champagne, salvaged from a shipwreck near the Finnish province of Aaland, local authorities said Monday.
Divers stumbled across a cargo of around 150 champagne bottles last July in a two-masted schooner which had run aground sometime between 1825 and 1830, and by last November experts had already identified the world's oldest Juglar and Veuve Clicquot brands among the bottles.
"When re-corking the almost 200-year-old bottles a third brand has now been discovered," Aaland authorities said in a statement.
Four bottles have been identified as having come from the Heidsieck & Co Monopole house, which is now owned by Vranken Pommery Monopole.
"In the 1800s and the beginning of the 1900s it was one of the leading champagne houses, and it was one of those that we expected we might find in the cargo," Richard Juhlin, one of the world's leading champagne experts, told AFP.
