The researchers discovered bottles of beers hidden in the shipwreck and are currently analyzing the contents of the bottles and try to reproduce the 200 year old beverage.
Back in 2010, a team of divers found and old schooner wreck on the bottom of the Baltic Sea, somewhere near Finland.
According to the experts, there is evidence pointing to the fact that the ship sank approximately 170 years ago. Apparently, there were many bottles of beer and champagne on board when the ship sank deep into the water.
While most of the beer bottles were filled with sea water, diluting the original beverage, the scientists were still able to find some samples of the ancient beer so that they could analyze and determine what the initial beer recipe could have been.
At first, drinking the old beers gave the researchers an unpleasant impression. According to them, the drink had a high level of organic acids which were produced by the bacteria that have lived in the bottles for so many years.
These bacteria gave the beer a vinegar-like taste and researchers described the beers as having a soured-milk flavor.
These aromas overpowered the original flavors of the beer which was fruity, malt and hop.
Because of this, the scientists had to turn to analytical testing of the beer. Results showed that samples taken from two beer bottles suggested that there were two different kinds of beer, based on the content of hop.
The analysis also showed that yeast-derived flavor compounds were somewhat similar to the modern day beers, with a little more content of phenylethanol, researchers say.
Those who are interested in finding out what these beers taste like can do so. The Stallhagen brewery produced a few beers inspired by the old recipes that date back to the 1800s.
The new findings on the ancient beer recipe were published in the Journal of Agricultural and Food Chemistry.
