Analysis Yields Clues to Chemical Composition, Natural Aging Of 100-Year-Old Beer

% of readers think this story is Fact. Add your two cents.


Stashed away and long-forgotten, a trio of century-old bottled beers recently discovered in the Czech Republic could help scientists better understand early 20th-century brewing practices, as well as the chemical changes that occur in beer over long periods of time. A report on the well-preserved lagers appears in ACS’ Journal of Agricultural and Food Chemistry.

Uncovered in 2015 during the reconstruction of an old brewery, 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 remained to gather dust. The beers were bottled in dark glass and well sealed. Taking advantage of this unique discovery, Jana Olšovská and colleagues sought to produce detailed chemical profiles of these 100-year-old beers and determine the long-term effects of lager beer aging.

Initial sensory analyses found that the beers ranged from intensely sulfuric to sour, and had off-flavors that ranged from fecal to fruity. Using high performance liquid chromatography and other techniques, the researchers compared the beers’ features to those of modern day brews. 

 
For example, the century-old beers had higher alcohol content and were less bitter. They also contained more iron, copper, manganese and zinc. There was also evidence of the particular yeasts used to make each of the beers, along with bacterial and fungal contaminants. The researchers conclude that chemical changes to two of the beers were likely caused by microbial contaminants while the third beer, which was better preserved, offered the best insights into the older brews’ natural aging processes.
