Divers discovered a shipwreck in the Åland archipelago in the summer of 2010. Five beer bottles were found from the shipwreck dating back to the beginning of the 1800's. The beers were analysed by VTT Technical Research Center of Finland. Microbes were isolated and identified and knowledge was gained about alcohol content, colour and bitterness of the beers. Researchers in KU Leuven University utilized the information gained from the shipwreck beers and recreated an authentic replica of the shipwreck beer carrying the name Stallhagen Historic beer 1843.
