Climate change is affecting the production of hops and barley, key ingredients in beer, by impacting water access, weather patterns, and crop yields. The European hops industry is projected to decline by 4-18% by 2050, threatening beer production globally. Researchers are working on developing drought-tolerant varieties of hops and exploring the potential of winter barley, but the challenges posed by climate change are daunting and may require significant adaptations by farmers and brewers.
