Help! Global warming is killing Czech beer! / Pomoc! Globalni oteplovani nici ceske pivo!

A recent study of the Czech Hydrometerological Institute concluded that “even with the modest warming so far experienced, hop yields in the Czech Republic have stagnated and quality declined”. The increasing temperatures (although very suttle) have been taking the toll on the ‘beer plants’ which in turn could reduce their yield by a further 7-10%. Perhaps the most worrying is the decline in the quality of the Saaz hops, which produce our good old Czech pilsners. “The “Alpha” acid content – “a major determinant of quality”, according to the team, as it’s the compound that produces a pilsner’s defining bitter taste – is likely to fall a further 13-32% if the predicted warming occurs. The study found that the concentration of these acids has fallen by 0.06% a year since 1954.” (more…)
