GDAŃSK, POLAND—A perfectly preserved stoneware bottle produced between 1806 and 1830 has been recovered from a shipwreck in the Baltic Sea. The corked bottle had been carrying mineral water from Selters, a naturally carbonated spring in Germany’s Taunus mountain range. “The bottle contains a liquid, and for sure it’s not seawater,” underwater archaeologist Tomasz Bednarz of the National Maritime Museum in Gdańsk told Discovery News. The bottle probably contains original Selters water, but it may have been reused and filled with wine. It will be opened under laboratory conditions.
