EASTBIO The Application of Advanced Analytical Techniques to Ensuring Flavour Sustainability and Optimisation in Scotch Whisky Distillery Fermentations


   School of Chemistry


About the Project

Scotch Whisky is integral to the UK economy, with annual exports worth approximately £5 bn. Its production is well understood and tightly regulated. Nevertheless, the chemical identity of many of the aromas that contribute to Scotch Whisky flavour, and their full relationship to the particulars of the production process, are unknown. Understanding how certain flavour compounds can be regulated within the fermentation process is of commercial importance in ensuring flavour sustainability, particularly when the industry is investigating process changes to align with its environmental sustainability aspirations.

This project builds on techniques developed during two previous collaborative PhD studentships with the Edinburgh-based Scotch Whisky Research Institute (SWRI). SWRI are recognised experts in the analysis of Scotch Whisky and are funded by the distilling industry to carry out strategic research on all aspects of Scotch Whisky production. The cutting-edge analytical instrumentation (600-800 MHz liquid-state NMR, 12T Fourier Transform Ion Cyclotron Resonance Mass spectrometry and an ion mobility capable Q-ToF with nanoESI, ESI and LC interfaces) based in the School of Chemistry, focussing on maturation and the ability to authenticate Scotch Whisky1, showed a much greater complexity to new make spirit than previously realised by low resolution studies.

These techniques will now be used to explore the impact of distillery fermentation on distillate composition and flavour by controlling the fermentation conditions such as yeast type, bacterial composition, fermentation time, water utilisation, temperature control or wort cloudiness.

The project will provide a high-quality training opportunity (http://www.chem.ed.ac.uk/studying/phd/graduate-school-overview) for a successful candidate at a world class University as well as offer excellent employment prospects. A six-month industrial placement at SWRI will provide experience in fermentation and flavour analysis using their dedicated facilities.

Eligibility:

Applicants must have an undergraduate degree in chemistry or biochemistry (> 2.1 or equivalent) and fulfil the eligibility criteria: https://www.ukri.org/wp-content/uploads/2020/10/UKRI-291020-guidance-to-training-grant-terms-and-conditions.pdf  Knowledge of programming languages such as Python is desirable.
