A third brand of champagne has been identified among the bottles salvaged from a shipwreck last summer, it has been announced.

When the 168 bottles of champagne were recovered off the coast of the Finnish province of Aaland in July, two brands were identified - Veuve Clicquot and the now-defunct Juglar.

However, it seems that when re-corking the 200-year-old bottles, a third brand was found among the number, Agence France-Presse reports.

Four of the bottles were identified as the produce of the Heidsieck & Co Monopole estate. It is thought that these wines could sell for more than €100,000 (£84,000) each at auction.

"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 the news agency.

Another historical wine discovery was made recently when archaeologists unearthed what is believed to be the world's oldest wine press in southern Armenia.

The stone press is thought to be over 6,000 years old.
