The oldest known drinkable Champagne, which was retrieved from a shipwreck in the Baltic Sea last year, will go under the hammer later this year.

Aaland, the autonomous province of Finland that owns the 200-year-old Champagne, has decided to auction off two bottles at an event in the capital of Mariehamn on June 3rd.

The sale will be organised by the American auction house Acker Merrall & Condit, and will comprise one bottle of Veuve Cliquot and another of Juglar.

According to Finnish news provider YLE, Champagne expert Richard Juhlin said the final price "can only be guessed at, but it will probably reach a record level".

Proceeds from the sale will be used for the public good, such as improving the state of the Baltic Sea, added a government representative.

Prior to the discovery, the world's oldest Champagne was believed to be a bottle of Perrier-Jouet 1825, which was opened and tasted in March 2009.
