Two bottled beers were recovered from a shipwreck in 2010 . Schooner was found off the coast of the Åland Islands , Finland . The ship sank on July 31, 1912 after colliding with another vessel while sailing between Stockholm and Turku. This was caused by bacteria that had grown in the bottles over the years . But chemical analysis of the samples revealed specific flavours . These include ‘ green leaf ’ flavours , sweet apple and rose compounds . This makes them similar to modern lagers and ales rather than stouts .
