Global warming will worsen the quality of beer

Global warming threatens to significantly reduce the taste of many beers. Scientists found that because of rising temperatures in the hops decreases the content of the substance responsible for the taste of beer, wrote scientific journal New Scientist.Kak passes Lenta.Ru, the authors studied the hops of Humulus lupulus, which is used in the production of Bohemian pilsner. Contained in the hop alpha acids provide characteristic bitter taste of the class piva.Issledovateli found that over the past 55 years the content of alpha-acids in H.lupulus annually falls on 0,06%. Based on existing climate change models, scientists estimate that in the near future, drop the content of alpha-acids range from 13 to 32%. According to colleagues, the study authors, the growth temperature will affect not only the Czech brewing industry. The quality of hops and falls in the eastern regions of Germany and in the central part Slovakii.Iz due to global warming some countries has already had to make serious political steps. For example, Italy and Switzerland moved their border that runs on alpine glaciers. In some areas the difference between the old and new boundaries of 150 meters.
