Whisky is ‘the water of life’ but in one of the driest starts to a year seen in Scotland, distillers are turning to researchers to improve access to the crucial water supplies for their unique products.
Scientists from the University of Aberdeen are leading a project funded by Chivas Brothers, the Pernod Ricard business dedicated to Scotch whisky and maker of Ballantine’s, to develop innovative nature-based solutions that could help to mitigate water scarcity but also slow down water run-off following rapid downpours.
The issue has been brought into sharp focus in recent weeks with the Scottish Environment Protection Agency (SEPA) issuing country-wide alerts for low water levels. The dry soil a long dry spell leaves in its wake can repel water rather than letting it soak in as damp soil would, meaning it is harder to hold water when and where it is most needed.
In areas like Speyside – home to half Scotland’s malt distillers – ensuring a continuous water supply, both now and in the future, is essential as temporary closures can cost the industry millions of pounds.
Chivas Brothers is funding new research led by the University of Aberdeen and working with the James Hutton Institute, following a successful project in 2022 which focused on The Glenlivet distillery.
There the team demonstrated the benefits of a series of small leaky dams installed in channels to slow water flow by holding the water in that location in temporary mini reservoirs. This allows it to soak into the subsurface so that more water is available at times when it is needed.
The new research will broaden the geographic scope of the project across Speyside and explore a wider range of possible nature-based solutions for water management.
Project lead Dr Josie Geris, a lecturer in hydrology at the University of Aberdeen, said the techniques they are investigating, including soil and vegetation management, could bring benefits beyond the whisky industry as around three percent of people living in Scotland rely on vulnerable private water supplies.
“First, we will take a comprehensive look at data gathered from across Speyside and carry out detailed monitoring at The Glenlivet and two other distillery sites to develop understanding of how surface water and groundwater are connected, and how this varies across the different locations.” she added.
“This will help us to assess how resilient different water resources in Speyside are to drought and to understand what causes certain water resources to be more vulnerable whether it is driven by geology, land use or other issues.
“We will then use modelling to help future planning and our understanding of which nature-based solutions might work best where to mitigate water scarcity across the region.”
The research team, which also includes Dr Mark Wilkinson (James Hutton Institute), Dr Ronald Daalmans (Chivas Brothers) Dr Jean-Christophe Comte, and PhD student Jennifer Pirie (University of
Aberdeen), will investigate a range of techniques at The Glenlivet, Glenburgie and Aberlour distilleries.
PhD student Jennifer Pirie, from the University of Aberdeen, said: “The techniques used successfully at Glenlivet cannot be applied everywhere and so we are looking at a range of measures to improve water availability in different environments.
“What works best where will depend on local site characteristics, like the geology and soil properties, and so it is vital we build this understanding and knowledge.”
As well as drought conditions, the techniques the team will use could also help with flooding and are applicable to other environmental issues such as improvements to carbon storage, water quality and biodiversity.
Dr Mark Wilkinson, from the James Hutton Institute, said: “There is significant interest from diverse stakeholders for these ‘green solutions’ to environmental problems and the project is designed to share insights and to develop a toolkit of options for different environments and users.”
Dr Ronald Daalmans, from Chivas Brothers, said: “This important work will help inform the whisky sector on how it can adapt and mitigate the effects of climate change for this critical resource. It forms part of a wider programme, called The River Within, which aims to support river restoration and enhancement in North-East Scotland.”
In addition to supporting research projects, Chivas Brothers’ The River Within, a long-term programme in partnership with three Scottish river trusts – the Deveron, Bogie and Isla Rivers Charitable Trust, Findhorn, Nairn and Lossie Rivers Trust, and the Spey Catchment Initiative – aims to support the delivery of habitat restoration projects to ultimately preserve, protect and improve the health of Scotland’s rivers and waterways.
