The bottles of Champagne found on 
the sea bed near the Aland Islands, between Sweden and Finland, are the brands Veuve Clicquot and Juglar (now absorbed into the Champagne House Jacquesson). A total of 168 bottles were raised in the salvage operation. Britt Lundeberg, Aland’s culture minister, has said that: “All bottles are not intact but the majority are in good condition.”
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 yet.
Veuve Clicquot confirmed that experts analysing the branding of the corks “were able to identify with absolute certainty” that at least three of the recovered bottles were Veuve Clicquot. 
The Champagne house, founded in 1772, said the branding featured a comet, added to pay tribute to one that crossed the skies of the Champagne region of France in 1811 “and was rumoured to be the cause of a harvest of remarkable quality.” (By the way if you are interested in this phenomenon check out Comet Vintages).
Here are some excerpts from Veuve Clicquot’s statement:
“Francis Hautekeur, winemaker of Veuve Clicquot, and Fabienne Moreau, historian, were able to positively identify the mark of Veuve Clicquot . . . This is the only way to identify the champagne, the b
ottles without labels. Three bottles were positively identified as Veuve Clicquot and the likelihood that we discover several others in the next few weeks is very high.
The route from the Baltic was frequently used for shipments to the Russian Imperial Court, who sealed the first commercial successes of the House. The brand of a comet that was added to the logo by Madame Clicquot to celebrate the comet that crossed the sky of Champagne in 1811, the year of a bumper crop.”
Francois Hautekeur, of Veuve Clicquot’s wine making team, described the Champagne as “a toasted, zesty nose with hints of coffee, and a very agreeable taste with accents of flowers and lime-tree.”
The Åland government plans to use the bottles to publicise this small, autonomous island region of Finland.
An auction is planned, together with other wine events. There are also
plans to make a special Cuvée of Champagne which will have the ancient wine as dosage.
A historian from Chalons-en-Champagne (Marne) is currently conducting research, commissioned by the Champagne House Jacquesson. It seems that in 1798 Claude Memmie Jacquesson established a negotiants in Champagne, with partner Francois-Felix Juglar.
In the late 18th century the partners bought a parcel of vines from the Hôpitaux de Châlons. They created cellars by digging into the hills of Mont Saint-Michel and their business developed rapidly in France and Europe: with up to 800,000 bottles shipped (60% in Europe),in the mid-19th century. It is therefore not surprising that they have turned up at the bottom of the sea! In 1810,the Emperor Napoleon, visited the cellars and awarded a gold medal to both Juglar and Jacquesson. In 1829, Memmie bought out Juglar and Memmie’s son, Adolphe, was the inventor of the wire basket that encapsulates the Champagne cork. Today the Champagne House is run by the Chiquet family.
