Divers found a shipwreck at the bottom of the Baltic Sea in 2010 near the tiny island of Aland.
The shipwreck was found with 168 bottles of champagne.
Most of the bottles were in perfect condition as they were preserved by the cold and dark environment of the sea.
Veuve Clicquot (A champagne house) began a scientific experiment called 'Cellar in the Sea' after getting inspired by the discovery.
The scientists will keep taking samples of the champagne for the next 40 years to analyse the ageing process under the water.
Experts say the remnants of the shipwreck was most likely being taken to either Bomsund or St. Petersburg in Russia.
