Researchers have discovered three bottles of beer that are estimated to be 100-years-old.
The three lager beers apparently were produced during the World War I era and stored in a large cold cellar at the brewery, where they were gathering dust. They tasted each beer, which had flavors that ranged from fecal to fruity. The old beers had higher alcohol content and were less bitter than beers today.
The beer, which was bottled in dark glass and well sealed, was discovered during the reconstruction of a brewery in Záhlinice.
They used a method called high-performance liquid chromatography as well as other techniques to compare the beers’ features to those of modern day brews.
The researchers concluded their study writing ‘One can assume that a century ago our ancestors produced beer from similar raw materials and in a similar way as today’.
