Graham Stewart joined the Labatt Brewing Company, London, Ontario in 1969 and devoted himself to the advancement of brewing science with an emphasis on yeast, firstly as a research microbiologist, subsequently, through various research positions, culminating in eight years as Director of Brewing Technical Affairs, with responsibility for strategic technical planning, research, process and product development, quality assurance, intellectual property management and technical education and training. His team’s subsequent achievements in the development of high gravity brewing and related process intensification concepts are widely acknowledged. In 1994, Heriot Watt University in Scotland recruited him to head the International Centre for Brewing and Distilling (ICBD) as Director, and Professor of Brewing and Distilling, a position he held until his retirement in 2007. He holds PhD and DSc degrees from the University of Bath, is a Visiting Professor at the University of Nottingham and currently is an Emeritus Professor at Heriot Watt University (who conferred on him an Honorary Doctorate for his contributions to education and research over the past 50 years). His Fellowships include: the American Academy of Microbiology, the Institute of Biology and the Institute of Brewing and Distilling (IBD). He has held various roles within the IBD, including being a Past President and he holds its highest award – the Horace Brown Medal. Further awards include: the Award of Distinction from the American Society of Brewing Chemists; the Award of Merit from the Master Brewers Association of the Americas and the Charles Thom Award from the Society of Industrial Microbiology. He has an academic publication record with over 300 titles that includes peer review papers, books, patents and review articles. His contributions to brewing and distilling education and training are considerable.
This book is an overview considering yeast and fermentation. The similarities and differences between yeasts employed in brewing and distilling are reviewed. The implications of the differences during the production of beer and distilled products (potable and industrial) are discussed.
This handbook includes a review of relevant historical developments and achievements in this field, the basic yeast taxonomy and biology, as well as fundamental and practical aspects of yeast cropping (flocculation), handling, storage and propagation. Yeast stress, vitality and viability are also addressed together with flavor production, genetic manipulation, bioethanol formation and ethanol production by non-Saccharomyces yeasts and a Gram-negative bacterium.
This information, and a detailed account of yeast research and its implications to both the brewing and distilling processes, is a useful resource to those engaged in fermentation, yeast and their many products and processes.
