(Decanter) - A cache of 200-year-old bottles of Champagne discovered at the bottom the Baltic is to be auctioned next month. Four bottles of Veuve Clicquot, six bottles from the now-defunct Champagne house Juglar, and one Heidsieck & Co go under the hammer at Mariehamn on 8 June. Mariehamn is the capital of the autonomous Åland archipelago between Finland and Sweden, near where the bottles were found in 2010 in a wrecked schooner dating from 1825-30.
