Beer in danger due to climate change

Climate warming, a growing concern around the world, is not only causing changes in the climate, it is also affecting the beer we enjoy. Scientists have warned that the quantity and quality of one of beer's key ingredients, hops, is affected by global warming , which could result in more expensive beers and require manufacturers to adapt their brewing methods, so according to The Guardian . The future of sustainable beer according to a new report A bitter challenge A recent study titled “ Climate-induced decline in quality and quantity of European hops requires immediate adaptation measures ” (2023), conducted by an international team of researchers, mostly from the Czech Republic, and published in the journal Nature Communications has projected that hop yields in European growing regions will decline by 4 to 18% by 2050 if farmers do not adapt to the warmer, drier climate. “Beer drinkers will definitely perceive climate change, whether in price or quality,” warns Miroslav Trnka, a scientist at the Global Change Research Institute of the Academy of Sciences of the Czech Republic and co-author of the study. "That seems to be inevitable from our data." Beer in danger due to climate change Beer, the third most popular beverage in the world after water and tea, is produced by fermenting malted grains such as barley with yeast.

It is typically flavored with hops, which are mostly grown in mid-latitudes and are sensitive to changes in light, heat, and water. In recent years, demand for high-quality hops has skyrocketed due to the rise of craft beers with more intense flavors. However, greenhouse gas emissions that cause global warming are putting this plant at risk, the study reveals. green beer The researchers compared the average Singapore Phone Number List annual hop production in the periods 1971-1994 and 1995-2018 and found "a significant decrease in production" of 0.13-0.27 tons per hectare. , in Slovenia, saw the largest decline in average annual hop yield, at 19.4%. In Germany, the world's second largest hop producer, average hop yields have decreased by  according to the study. Hop varieties in Europe are known for their quality, but lack of rain and higher temperatures mean reduced yields, as well as a lower concentration of the special compounds that give beer its bitter taste. Climate change is affecting the quality of beer Brewing in Central Europe has a history dating back thousands of years and is a pillar of culture.



According to a report by Japanese brewer Kirin, people in the Czech Republic consume more beer than anywhere else in the world. In Germany, where beer brewing has been regulated for 500 years by a "purity law," Oktoberfest, the world's largest beer festival, held annually in Munich, Germany, welcomes 6 million beer lovers. beer from all over the world in their tents every year. The flavor of beer does not depend solely on hops, but hops play an important role in the drink's popularity, Trnka says. "In the bars of Europe, the most frequent debate, apart from the weather and politics, is about... beer." However, climate and politics are changing the taste of beer. World leaders have pledged to try to prevent the planet from warming more than 1.5°C above pre-industrial levels by the end of the century, but they are emitting too many greenhouse gases to meet that goal. A future without beer… As temperatures increase and precipitation decreases, some hop growers have moved their crops to higher elevations, valley locations with more water, and changed the spacing of crop rows. Andreas  a hop farmer in Spalt, southern Germany, notes that the total amount of rain in his fields has changed little, but now "the rain does not come at the right time." He has therefore built an irrigation system to feed the hops at critical times.
