How Climate Change May Alter the Flavor Profile of Your Gin and Tonic: Key Findings from New Research

Scientists have discovered that climate change could alter the flavor of gin and tonic. Changes in weather patterns might affect the taste of juniper berries, which are essential for gin’s unique flavor.

Researchers at Heriot-Watt University’s International Centre for Brewing and Distilling (ICBD) conducted a study that showed how shifts in climate could influence the chemical makeup of these berries. Just like wine, juniper berries develop their own "terroir," which depends on factors like rainfall and sunlight.

Matthew Pauley, an assistant professor at ICBD, pointed out that when harvests are wetter, the volatile compounds in the berries can decrease by around 12%. This reduction can have serious impacts on how gin tastes.

The team analyzed berries from several European regions, including Italy and Kosovo, looking at how different weather conditions affected the flavor compounds. They found distinct chemical profiles across regions, which can result in various flavors, ranging from woody to citrusy notes. Wetter conditions lead to longer drying times for the berries, changing their water-soluble chemical content.

Prof. Annie Hill, who supervised the study, noted that the least water-soluble compounds are significantly influenced by the drying process after harvest.

For gin makers, this variability poses a challenge. The industry, worth billions, thrives on consistency and quality. Many producers choose specific berries from regions known for their flavor profiles, but shifting climate patterns could disrupt this careful selection.

In addition to this study, a recent survey highlighted that 70% of consumers are more aware of the factors that influence food and drink quality. This growing awareness may put more pressure on distillers to ensure the integrity of their flavors amidst changing climates.

As the industry adapts to these challenges, it will be interesting to see how distillers navigate the balance between tradition and the unpredictable effects of climate change. You can explore more about the research in the Journal of the Institute of Brewing.
