Someone once said that 'wine is a mixture of chemistry, biology and psychology'. It has certainly fascinated people over the centuries and without a doubt been enjoyed by many. Indeed, from its serendipitous roots as an attempt to store fruit, wine has been woven into the fabric of society; from its use in religion to today's sophisticated products sampled over a meal. The Chemistry and Biology of Winemaking not only discusses the science of winemaking but also aims to provide the reader with a wider appreciation of the impact of oenology on human society. Beginning with a history of wine the book discusses a wide range of topics, with particular emphasis on the organisms involved. Starting with the role of yeast in fermentation, it goes on to discuss so-called 'killer yeasts', lactic acid bacteria and the role that genetically modified organisms may have in the future. This book is ideal for anyone interested in the process of winemaking and will be of particular use for those with an interest in the chemical and biological sciences.
The aim of this book is to describe chemical and biochemical aspects of winemaking that are currently being researched. The authors have selected the very best experts for each of the areas. The first part of the book summarizes the most important aspects of winemaking technology and microbiology. The second most extensive part deals with the different groups of compounds, how these are modified during the various steps of the production process, and how they affect the wine quality, sensorial aspects, and physiological activity, etc. The third section describes undesirable alterations of wines, including those affecting quality and food safety. Finally, the treatment of data will be considered, an aspect which has not yet been tackled in any other book on enology. In this chapter, the authors not only explain the tools available for analytical data processing, but also indicate the most appropriate treatment to apply, depending on the information required, illustrating with examples throughout the chapter from enological literature.
Wine chemistry inspires and challenges with its complexity, and while this is intriguing, it can also be a barrier to further understanding. The topic is demystified in Understanding Wine Chemistry, Special Mention awardee in the 2018 OIV awards, which explains the important chemistry of wine at the level of university education, and provides an accessible reference text for scientists and scientifically trained winemakers alike. Understanding Wine Chemistry: Summarizes the compounds found in wine, their basic chemical properties and their contribution to wine stability and sensory properties Focuses on chemical and biochemical reaction mechanisms that are critical to wine production processes such as fermentation, aging, physiochemical separations and additions Includes case studies showing how chemistry can be harnessed to enhance wine color, aroma, flavor, balance, stability and quality. This descriptive text provides an overview of wine components and explains the key chemical reactions they undergo, such as those controlling the transformation of grape components, those that arise during fermentation, and the evolution of wine flavor and color. The book aims to guide the reader, who perhaps only has a basic knowledge of chemistry, to rationally explain or predict the outcomes of chemical reactions that contribute to the diversity observed among wines. This will help students, winemakers and other interested individuals to anticipate the effects of wine treatments and processes, or interpret experimental results based on an understanding of the major chemical reactions that can occur in wine.
More than 150 years after Louis Pasteur attributed fermentation to a living organism, the field of wine microbiology and chemistry is vibrant with discovery. The last decade alone has seen great strides in our understanding of the biochemistry involved in vinification. In this new edition of his classic text, Yair Margalit gives the complete and current picture of the basic and advanced science behind these processes, making the updated Concepts in Wine Chemistry the broadest and most meticulous book on the topic in print. Organized to track the sequence of the winemaking process, chapters cover must and wine composition, fermentation, phenolic compounds, wine oxidation, oak products, sulfur dioxide, cellar processes, and wine defects. Margalit ends with chapters detailing the regulations and legal requirements in the production of wine, and the history of wine chemistry and winemaking practices of old.
This book, written by experts, aims to provide a detailed overview of recent advances in oenology. Book chapters include the latest progress in the chemistry and biochemistry of winemaking, stabilisation, and ageing, covering the impact of phenolic compounds and their transformation products on wine sensory characteristics, emerging non-thermal technologies, fermentation with non-Saccharomyces yeasts, pathways involved in aroma compound synthesis, the effect of wood chips use on wine quality, the chemical changes occurring during Port wine ageing, sensory mechanisms of astringency, physicochemical wine instabilities and defects, and the role of cork stoppers in wine bottle ageing. It is highly recommended to academic researchers, practitioners in wine industries, as well as graduate and PhD students in oenology and food science.

Enological Chemistry is written for the professional enologist tasked with finding the right balance of compounds to create or improve wine products. Related titles lack the appropriate focus for this audience, according to reviewers, failing either to be as comprehensive on the topic of chemistry, to include chemistry as part of the broader science of wine, or targeting a less scientific audience and including social and historical information not directly pertinent to the understanding of the role of chemistry in successful wine production. The topics in the book have been sequenced identically with the steps of the winemaking process. Thus, the book describes the most salient compounds involved in each vinification process, their properties and their balance; also, theoretical knowledge is matched with its practical application. The primary aim is to enable the reader to identify the specific compounds behind enological properties and processes, their chemical balance and their influence on the analytical and sensory quality of wine, as well as the physical, chemical and microbiological factors that affect their evolution during the winemaking process. - Organized according to the winemaking process, guiding reader clearly to application of knowledge - Describes the most salient compounds involved in each step enabling readers to identify the specific compounds behind properties and processes and effectively work with them - Provides both theoretical knowledge and practical application providing a strong starting point for further research and development

In Postmodern Winemaking, Clark Smith shares the extensive knowledge he has accumulated in engaging, humorous, and erudite essays that convey a new vision of the winemaker's craft--one that credits the crucial roles played by both science and art in the winemaking process. Smith, a leading innovator in red wine production techniques, explains how traditional enological education has led many winemakers astray--enabling them to create competent, consistent wines while putting exceptional wines of structure and mystery beyond their grasp. Great wines, he claims, demand a personal and creative engagement with many elements of the process. His lively exploration of the facets of postmodern winemaking, together with profiles of some of its practitioners, is both entertaining and enlightening.
"The Science of Wine does an outstanding job of integrating 'hard' science about wine with the emotional aspects that make wine appealing."--Patrick J. Mahaney, former senior Vice President for wine quality at Robert Mondavi Winery "Jamie Goode is a rarity in the wine world: a trained scientist who can explain complicated subjects without dumbing them down or coming over like a pointy head. It also helps that he's a terrific writer with a real passion for his subject."--Tim Atkin MW, The Observer
