Understanding Wine Chemistry (eBook)

Professor Andrew L. Waterhouse, Department of Viticulture & Enology, University of California, Davis, USA. Andrew Waterhouse received his PhD in organic chemistry from UC Berkeley, and has been a wine chemist at the University of California, Davis since 1991. He teaches wine analysis, graduate level wine chemistry, and an online introductory wine course, and is Chair of the Viticulture and Enology graduate studies program. Former graduate students and postdocs are academics, industry scientists and winemakers. His research lab has reported key wine oxidation reactions and has developed new methods to analyse wine components including those using LC-MS with isotope filtering, as well as NMR techniques. The research has focused on wine phenolics, oak compounds and oxidation products. In addition his lab has also been addressing the metabolic products of phenolics. He publishes in numerous international journals in the fields of chemistry and agriculture, and serves as a chief editor at the Journal of the Science of Food and Agriculture.

Gavin Sacks received his PhD in analytical chemistry from Cornell University, and following post-doctoral studies in nutritional sciences and biogeochemistry he began as a faculty in food science at Cornell in 2007. He has served as Director of Undergraduate Studies for Cornell's interdepartmental Viticulture and Enology undergraduate major, in which he also teaches courses in wine analysis and in wine flavor chemistry. His research interests include the development of both low-cost and state-of-the-art approaches to analysis of odorants and other organoleptically important compounds; and applying these tools to understanding the role of plant genetics, cultural practices, and post-harvest processing on sensory attributes of foods and beverages, particularly of wine. Dr David Jeffery, School of Agriculture, Food and Wine, University of Adelaide, Australia. David Jeffery received his PhD in synthetic organic chemistry from Flinders University, and has been involved with wine chemistry for over a decade, initially as a researcher at The Australian Wine Research Institute before transitioning to The University of Adelaide in 2010. He teaches wine chemistry to undergraduate and Master level students, delivering topics associated with stabilization, clarification, distillation, wine aroma, polyphenols, and analytical methods. He also helped to develop and deliver a free online wine education course called Wine 101x, offered on the EdX platform. David's research areas extend to on many aspects of wine chemistry, with special interests in polyphenols and aroma compounds and their precursors. He utilizes his expertise in synthetic organic chemistry and natural product isolation, purification and characterization, along with experience in developing and applying analytical methods, to improve understanding of grape and wine chemistry, particularly in relation to chemical composition and quality.

"The book brings some new approaches of chemistry knowledge concerning wine composition, control and production. Each chemical family that can be find in grapes and wines have been studied with updates of the last knowledge in the field including structures and levels in grapes and wines with flavour and taste thresholds. Wine components and their reactions, as well as their role and sensory potential effects are included in a synthetic way. Off-flavours, taints and winemaking itinerary are also listed and updated. Biochemistry deals with major (bio) chemical reactions that occur during alcoholic fermentation and their role in forming secondary odorants and other important compounds in wine. Wine ageing including oak use is well described as well as the most relevant aspects of wine stabilization and fining, additives and processing aids. The book gives updated and accessible reference text for scientists, oenologists and scientifically trained winemakers. The book will be useful for students in the vines and wines field and will attract, researchers and consumers" Professor Pierre-Louis Teissedre, Université de Bordeaux- Institut des Sciences de la Vigne et du Vin, April 2017
