Stock up, beer drinkers
Global warming threatens beer quality
Climate change may cause a decline in beer quality, according to a study led by scientists at the Czech Hydrometeorological Institute.
The study that claims hop yields in the Czech Republic have declined over recent years—likely due to modest increases in air temperature over the last five decades—and yields could be cut back by 7 percent to 10 percent in the future.
Pilsner beer, which is made with special Saaz hops, which grows in the Czech Republic, faces the biggest threat. The alpha acid content of Czech pilsners, which gives the beer a bitter taste, is likely to see its yield decrease by 13 percent to 32 percent in the future if the warming continues at its current rate.
