The Impact of Climate Change on Craft Beer

Climate change has been a pressing concern for our planet for many years, with its effects becoming increasingly apparent over time. From more intense storms to extreme weather conditions, no one is immune to the consequences of rising global temperatures. And now, it seems that even beer lovers are feeling the impact, as climate change threatens the main ingredient in craft beer: hops.

A recent study published in the renowned science journal, Nature, has shed light on the potential effects of climate change on the availability and quality of hops. These essential ingredients are predominantly grown in specific regions with suitable environmental conditions. However, as our planet continues to warm, both the quantity and quality of hops are being significantly affected, leading to potential changes in price and taste for craft beer enthusiasts.

According to the study, researchers predict a decline of 4 to 18 percent in hops yields by 2050, accompanied by a 20 to 30-percent decline in “alpha content.” Alpha content refers to the measurement of alpha acids in hops, which determines the bitterness of the beer. With the rise in popularity of craft beer and the preference for high-quality hops, low-alpha beers have already seen a decline in recent years.

The impact can be seen in the high-quality aroma hops harvested in Germany, Czechia, and Slovenia. Researchers discovered a significant decrease in European hop production from 1971 to 1994 and again from 1995 to 2018. This decline was accompanied by a decrease in alpha content, and the growing season for hops started 13 days earlier, negatively impacting their quality. With projections of increased droughts in southern and central Europe, there are concerns that the area suitable for growing aroma hops may need to expand by 20 percent to compensate for the decrease in alpha content.

As a result, beer lovers may soon experience an increase in prices and a change in the flavors they have grown to love. Until then, it is essential to savor and enjoy your favorite craft beers while they still maintain their familiar aroma and taste. However, it is important to mentally prepare for the potential changes that lie ahead as our planet continues to warm.

In conclusion, climate change poses a significant threat to the craft beer industry, as the availability and quality of hops are being compromised. As responsible consumers, it is crucial to be aware of the environmental factors influencing the beers we enjoy and support efforts to combat climate change to preserve this cherished beverage for future generations.
