Scottish distilleries are increasingly turning to scientific innovation in response to unprecedented water shortages that are jeopardising their production capabilities. As climate conditions shift, particularly during one of Scotland's driest starts to the year, firms are recognising the vital importance of sustainable water management. This growing concern prompted the University of Aberdeen to embark on pioneering research, funded by the whisky business Chivas Brothers, to develop nature-based solutions aimed at alleviating water scarcity issues.

In recent weeks, the Scottish Environment Protection Agency (SEPA) issued nationwide alerts regarding low water levels, alarming distillers, especially in key regions such as Speyside, home to half of Scotland's malt distillers. These conditions necessitate continuous access to water—the lifeblood of whisky production. The innovative project led by scientists from the University of Aberdeen and the James Hutton Institute seeks to broaden research initiatives, building on previous successes, such as those at The Glenlivet distillery, where small leaky dams were installed to capture water during wet periods for use during droughts.

Dr Josie Geris, a hydrology lecturer at the University of Aberdeen and project lead, emphasised the importance of understanding local hydrological characteristics. "We will take a comprehensive look at data gathered from across Speyside," she stated. This research aims not only to benefit the whisky industry but also to safeguard the water supply for the three per cent of the Scottish population reliant on vulnerable private water sources.

The team is exploring various nature-based solutions for water management, such as enhancing soil and vegetation, which could yield benefits beyond the distilleries. These efforts are essential, especially considering the anticipated increase in heatwaves due to climate change, which threaten water availability. By focusing on hydrological models, they plan to determine which measures are most effective in different environments.

PhD student Jennifer Pirie noted the diversity of environments across Speyside and the need for tailored approaches. "What works best where will depend on local site characteristics," she explained. This level of detail is crucial for developing solutions that can effectively mitigate water scarcity while also addressing flooding and improving carbon storage and biodiversity. Such initiatives are indicative of the whisky sector's commitment to tackling climate change.

The River Within, a broader programme associated with this research, aims to restore and enhance river ecosystems in northeast Scotland. Collaborating with multiple river trusts, the initiative includes habitat restoration projects designed to protect and improve the health of Scotland's rivers and waterways. According to Dr Ronald Daalmans of Chivas Brothers, this partnership not only supports whisky production but crucially addresses the pressing challenges posed by climate change.

Chivas Brothers exemplifies a commitment to sustainability within the whisky industry. Their Dalmunach Distillery has employed energy-efficient measures that significantly reduce environmental impact, achieving substantial savings in energy, greenhouse gas emissions, and water consumption over nearly a decade. Additionally, their exploration of biogas production from distillery waste represents a forward-thinking approach to waste management and energy use.

As the whisky industry navigates these challenging environmental conditions, the interconnection between academic research and practical applications illustrates a proactive response to climate challenges. The collaboration among scientists, distilleries, and environmental organisations heralds a new chapter in whisky production—one that harmonizes tradition with innovation, ensuring the sector's resilience amidst evolving climate realities.

In a world increasingly affected by climate-related demands, the lessons learned in Speyside could serve as a model for other industries grappling with similar sustainability challenges. As project insights and strategies are developed, they promise not only to sustain whisky production but also to enrich Scotland’s environmental landscape for generations to come.
