Ever been subjected to a bitter pint in Prague?
Most bottled beer in the country comes with a born-on date to ensure freshness, but researchers from Prague’s Research Institute of Brewing and Malting recently unearthed a trio of bottles dating back to the WWI era.
Yes, of course Prague has a Research Institute of Brewing and Malting (www.beerresearch.cz), the only facility of its kind in the Czech Republic.
The three bottles were located covered in dust at the old Raven Trading brewery in Záhlinice, which is currently undergoing reconstruction.
You might be wondering how a scientific institute analyzes beer. The best way to research beer, as many Prague residents already know, is to taste it firsthand. And that’s exactly what the researchers did.
How were the 100-year-old brews?
A bottle of 10.3° Plato was noted to have “sulfuric and fecal off-flavors” by the researchers, but the other two bottles fared better.
A 7.6° was “dark and very acidic, resembling Lambic,” while “sweetness, honey and fruity off-flavors” were detected in the final 10.4°.
All three beers were estimated to be lager-type brews, with the research possible thanks to good storage conditions.
Their report was submitted to the scientific Journal of Agricultural and Food Chemistry, and published online earlier this month.
UK tabloid The Daily Mail picked up on the researcher’s findings yesterday.
