As well as being a whisky connoisseur, Mike Billett is a highly regarded peatland scientist with a background in geology, soil and water science. During his 40-year career in research and education - at the Universities of Edinburgh and Stirling and at the UK Centre for Ecology and Hydrology - he researched and wrote extensively on the peatlands of the British Isles, Scandinavia and the Arctic, focusing on water quality, carbon, peatland management and environmental change, writing many research papers, book chapters, reports, and articles. In recent years he has immersed himself in the landscapes, taste and qualities of Scotland's single malt whiskies and has applied his deep understanding of the science of peatlands to this passion. Peat and Whisky is his first non-academic book.
