Germany & Czech Republic: Climate Change Plagues Hop Harvests

European hop planters are facing severe challenges during this year's seasonal harvest. Driven by prolonged periods of extreme heat and insufficient precipitation during critical growth phases, the national crop in Germany is projected to experience a substantial contraction. According to initial assessments by the Verband Deutscher Hopfenpflanzer (German Hop Growers' Association), the total German harvest is anticipated to decrease by approximately 22 percent, reaching an estimated volume of 33,800 metric tons (338,000 hl equivalent in processed form).

In Bavaria, home to the primary cultivation area of the Hallertau, agricultural authorities emphasize that structural challenges continue to strain local farming operations. Bavarian State Minister Michaela Kaniber pointed out during the official harvest launch that adapting to climatic shifts remains a paramount long-term priority for the sector. While initiatives such as newly established irrigation projects in the Hallertau aim to secure water supplies for hundreds of participating farms, rising temperatures and stringent regulations regarding plant protection products complicate daily operations. These developments follow preceding years of structural adjustments and reduced cultivation footprints across European hop-growing regions (inside.beer, 11.06.2026).

Simultaneously, the search for sustainable solutions is accelerating. In the Czech Republic, the Hop Research Institute in Žatec (Saaz) is cultivating up to 600 different hop genotypes in its breeding gardens to secure the future of beer production. Vladimír Nesvadba, head of the hop breeding department at the institute, highlighted in a report by Radio Prague International that traditional varieties, such as the renowned Saazer semi-early red-bine hop, are increasingly vulnerable to extreme drought and heatwaves.

To counteract these climatic pressures, researchers have developed the new ART hop variety, which was officially registered last year. With an expected initial harvest of around 100 kilograms this year, ART represents a critical step towards what growers are calling "Hop 2.0"—a new generation of plants specifically engineered for higher resilience against temperature extremes and water scarcity. Developing a new variety typically takes around 15 years from the first crossbreeding to official registration.

 Furthermore, the Czech research facility is analyzing original clones from its gene bank to compare growth, yield, and alpha-acid content under current climate conditions. To support these vital breeding programs and address the acute water shortage in hop gardens, targeted investments of CZK 40 million to CZK 60 million (EUR 1.64 million to EUR 2.46 million) are planned for the upcoming year. These measures are complemented by state subsidies for local growers to build private irrigation systems, including retention basins and pumping stations.
