Shipwrecked beer, recently discovered.
According to the linked article, a Finnish team of divers found five bottles of beer, thought to be from the 1840s, in a Baltic Sea shipwreck. The beer was well-preserved in corked bottles and has been analyzed by a Finnish lab. Now, using those findings, the Stallhagen brewery will produce a beer to match what our ancestors drank.
Add in a little intrigue - were there Scandinavian pirates? - and you have got the makings of a movie I would totally watch.
