Some breweries have taken to resurrecting the flavors of ages past. Adventurous beer makers are extrapolating recipes from clues that archeologists have uncovered from old and even ancient brews found at historical sites. Now scientists have analyzed some of the oldest preserved beer samples from an 1840s' shipwreck to try to provide insight into how they were made. They report their findings in ACS' Journal of Agricultural & Food Chemistry.
Brian Gibson and colleagues explain that in 2010, divers discovered an old schooner at the bottom of the Baltic Sea near Finland. Archeological evidence suggested the ship went down about 170 years ago. It was loaded with goods including bottles of champagne and beer. The beer was diluted with salt water, but it contained enough of the original ingredients for the researchers at VTT Technical Research Centre of Finland Ltd. and the Technical University of Munich to analyze and get an idea of the initial recipe.
When the researchers took a sip, they weren't able to discern the beers' intended flavors. High levels of organic acids, produced by bacteria growing in the bottles for years, gave the samples vinegary, "goaty" and soured milk flavors that overpowered the original fruity, malt or hop profiles. However, analytical testing created a picture of what the beer may once have been composed of. For example, they determined that samples from two bottles were different beers based on their hop content. They also found that yeast-derived flavor compounds were similar to those of modern beers, though with a higher than usual content of rose-like phenylethanol.

Abstract Two bottles of beer from an about 170-year-old shipwreck (M1 Fö 403.3) near the Åland Islands in the Baltic Sea were analyzed. Hop components and their degradation compounds showed that the bottles contained two different beers, one more strongly hopped than the other. The hops used contained higher levels of β-acids than modern varieties and were added before the worts were boiled, converting α-acids to iso-α-acids and β-acids to hulupones. High levels of organic acids, carbonyl compounds, and glucose indicated extensive bacterial and enzyme activity during aging. However, concentrations of yeast-derived flavor compounds were similar to those of modern beers, except that 3-methylbutyl acetate was unusually low in both beers and 2-phenylethanol and possibly 2-phenylethyl acetate were unusually high in one beer. Concentrations of phenolic compounds were similar to those in modern lagers and ales.

Hmmm. Study science later.
Interesting article:)
It’ll take a while to digest the findings.
Do I have to say again what I think of Beer ? LOL
They’ll spend a few hundred thou to re-create it, only to discover the taste is a dead-on ringer for Pabst Blue Ribbon.
Interesting!
“Sir, we got the lab report on the ancient beer...”
“Two parts sperm whale p!ss - what!!??”
Even an ancient sailor, shipwrecked for years on a deserted island, with nothing to eat but fish and drink rain water would not drink that!...................
I would have to try ALL of them to make sure of my ‘findings’..................
I can understand how wine came about, probably accidentally, thousands of years ago, grape juice fermented in the storage containers and produced alcoholic wine.
But, how did they ancients, the Egyptians most likely, INVENT BEER? The process is fairly complicated and involves research and trial and error to get the final product just right. One does not ‘accidentally’ make beer...............................
Another thing is that practically every culture that has ever existed, even to Amazonian natives in the jungles of Brazil, has produced some sort of alcoholic drink, even the Inuits and Eskimos. Some involved using fermented fish heads while others chewed up a starchy root and spit it into a container to ferment....................
LOL...no...I don’t think savage Vikings could be that crass as to devise such a disgusting creation!
The vilest beer I ever had, oddly enough, came from Germany. A Rauchbier........smoke beer, literally, tasted like a burned out tire.....................
With fish heads there's a fine line between fermented and rotten...
Have you tried He-Brew? From Israel, I think. Strong and (to my taste) undrinkably bitter.
Thanks Red Badger.
Somewhere boxed in my library I have a brewing book from the mid-1800s. Bought it for a dollar in the 90s.
Maybe Dogfish Head will do some of this. I hope.
