Chemists Analyze Beer From 170 Years Ago

old beer is rather similar to modern beer

Via Sci-News:

“Compared to modern beers, the shipwreck beers contained similar levels of potassium but 15- to 60-fold more sodium, presumably derived from sea water. This may have diluted the beers up to 30%,” the scientists wrote in the paper published in the Journal of Agricultural & Food Chemistry.

“Ethanol contents were low (2.8-3.2%) compared to typical modern lagers and ales. The mass ratios of glycerol and ethanol were 4.5% for both shipwreck beers, which is typical for a yeast fermentation product.”

Dr Gibson and his colleagues analyzed samples from two bottles recovered in the shipwreck.

They determined that the samples were different beers based on their hop content.

The Oldest Piece of Rock on Earth

This piece of rock is 4.4 BILLION years old. DAYUM!

esearchers involved in the discovery said that the discovery was of high scientific value. Earth's crust formed relatively quickly after the formation of our planet, and this little gem is a remnant of the original crusty crew. According to the University of Wisconsin scientist who led the investigation, John Valley, the survival of the crystal suggests that the early planet was not quite as harsh a place as commonly accepted in the scientific community. It lends support to the "cool early Earth" theory, which says that hydrosphere and liquid water existed before 4.3 billion years ago.
