The divers originally said the bottles were believed to be from the 1780s but experts later dated the champagne to the early 19th century. The exact years have not been established.
French champagne house Perrier-Jouet, a subsidiary of Pernod Ricard, has earlier stated that their vintage from 1825 is the oldest recorded champagne still in existence.
Some of the bottles will be sold at an auction, where Juhlin said they could fetch more than $70,000 apiece.

The World's Oldest Champagne
168 bottles of champagne have been salvaged from a 200-year-old shipwreck in the waters off the Aland Islands near Finland.
The bottles recovered are Veuve Cliquot and Juglar. Richard Juhlin, a champagne geek, has sampled them and reports, "An accent of mushrooms merged with sweet notes of honey."
