À chaque étape de l’élaboration du vin, le vinificateur n’est pas seul ; il cohabite avec d’invisibles « collègues » : les micro-organismes. Chaque vinificateur se doit de bien connaître les micro-organismes qui agissent dans son moût puis dans son vin, et de distinguer ceux qui peuvent être bénéfiques ou au contraire préjudiciables. Ces dernières années, les méthodes d’analyse génétique ont considérablement fait progresser la microbiologie du vin. La fermentation malolactique et les bactéries lactiques du vin ont été pleinement concernées par cet essor des connaissances scientifiques. La fermentation malolactique est une étape relativement récente dans le processus d’élaboration des vins, mais d’une importance considérable. Tous les travaux réalisés en amont (qualité des raisins, déroulement de la fermentation alcoolique) et en aval (élevage, stabilisation et préparation du vin à son conditionnement) peuvent être affectés par son déroulement.Cependant, la fermentation malolactique reste bien souvent une étape de la vinification aléatoire et insuffisamment maîtrisée. Cet ouvrage est le premier travail de synthèse qui aborde à la fois les bases scientifiques fondamentales sur les bactéries lactiques du vin et le processus de fermentation malolactique, les développements récents de la recherche (dans sa première partie) et des situations rencontrées en production, au travers de nombreuses expérimentations et observations de terrain (dans sa seconde partie). Illustré de nombreux exemples précis et de protocoles détaillés, cet ouvrage s’adresse à tous les praticiens et professionnels du vin. Les œnologues, les producteurs, les laboratoires et les étudiants en œnologie y trouveront de nombreuses informations techniques leur permettant de mieux appréhender la complexité de la fermentation malolactique, d’optimiser son déroulement dans leur chai ainsi que les outils adaptés pour solutionner certaines situations problématiques précises. Les chercheurs y trouveront les applications pratiques de leurs travaux et des voies d’amélioration possibles afin de mieux répondre aux problématiques de terrain rencontrées au quotidien par les praticiens.

The "Microbiology" volume of the new revised and updated Handbook of Enology focuses on the vinification process. It describes how yeasts work and how they can be influenced to achieve better results. It continues to look at the metabolism of lactic acid bacterias and of acetic acid bacterias, and again, how can they be treated to avoid disasters in the winemaking process and how to achieve optimal results. The last chapters in the book deal with the use of sulfur-dioxide, the grape and its maturation process, harvest and pre-fermentation treatment, and the basis of red, white and speciality wine making. The result is the ultimate text and reference on the science and technology of the vinification process: understanding and dealing with yeasts and bacterias involved in the transformation from grape to wine. A must for all serious students and practitioners involved in winemaking.

As an applied science, enology is a collection of knowledge from the fundamental sciences including chemistry, biochemistry, microbiology, bioengineering, psychophysics, cognitive psychology, etc., and nourished by empirical observations. The approach used in the Handbook of Enology is thus the same. It aims to provide practitioners, winemakers, technicians and enology students with foundational knowledge and the most recent research results. This knowledge can be used to contribute to a better definition of the quality of grapes and wine, a greater understanding of chemical and microbiological parameters, with the aim of ensuring satisfactory fermentations and predicting the evolution of wines, an7thd better mastery of wine stabilization processes. As a result, the purpose of this publication is to guide readers in their thought processes with a view to preserving and optimizing the identity and taste of wine and its aging potential. This third English edition of The Handbook of Enology, is an enhanced translation from the 7h French 2017 edition, and is published in print as individual themed volumes and as a two-volume set, describing aspects of winemaking using a detailed, scientific approach. The authors, who are highly-respected enologists, examine winemaking processes, theorizing what constitutes a perfect technique and the proper combination of components necessary to produce a quality vintage. They also illustrate methodologies of common problems, revealing the mechanism behind the disorder, thus enabling a diagnosis and solution. Volume 1: The Microbiology of Wine and Vinifications addresses the first phase of winemaking to produce an "unfinished" wine: grading grape quality and maturation, yeast biology then adding it to the grape crush and monitoring its growth during vinification; and identifying and correcting undesired conditions, such as unbalanced lactic and acetic acid production, use of sulfur dioxide and alternatives, etc. Coverage includes: Wine microbiology; Yeasts; Yeast metabolism; The conditions for the development of yeasts; Lactic acid bacteria, their metabolism and their development in wine; Acetic bacteria; The use of sulfur dioxide in the treatment of musts and wines; Products and processes acting in addition to sulfur dioxide; Winemaking; The grape and its maturation; Harvesting and processing of grapes after harvest; Vinification in red and white wine making. The target audience includes advanced viticulture and enology students, professors and researchers, and practicing grape growers and vintners.

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.

Many aspects of both grape production and winemaking influence wine sensory properties and stability. Progress in research helps to elucidate the scientific basis of quality variation in wine and to suggest changes in viticulture and oenology practices. The two volumes of Managing wine quality review developments of importance to wine producers and researchers. The focus is on recent studies, advanced methods and likely future technologies.Part one of the second volume Oenology and wine quality opens with chapters reviewing the impact of different winemaking technologies on quality. Topics covered include yeast and fermentation management, enzymes, ageing on lees, new directions in stabilisation, clarification and fining of white wines and alternatives to cork in wine bottle closures. Managing wine sensory quality is the major focus of part two. Authors consider issues such as cork taint, non-enzymatic oxidation and the impact of ageing on wine flavour deterioration. The volume concludes with chapters on the management of the quality of ice wines and sparkling wines.With authoritative contributions from experts across the world's winemaking regions, Managing wine quality is an essential reference work for all those involved in viticulture and oenology wanting to explore new methods, understand different approaches and refine existing practices. - Reviews the impact of different technologies on wine quality - Discusses yeast and fermentation management, enzymes and ageing on lees - Considers issues surrounding wine sensory quality including cork taint and the impact of ageing on flavour deterioration

The second edition of the book begins with the description of the diversity of wine-related microorganisms, followed by an outline of their primary and energy metabolism. Subsequently, important aspects of the secondary metabolism are dealt with, since these activities have an impact on wine quality and off-flavour formation. Then chapters about stimulating and inhibitory growth factors follow. This knowledge is helpful for the growth management of different microbial species. The next chapters focus on the application of the consolidated findings of molecular biology and regulation the functioning of regulatory cellular networks, leading to a better understanding of the phenotypic behaviour of the microbes in general and especially of the starter cultures as well as of stimulatory and inhibitory cell-cell interactions during wine making. In the last part of the book, a compilation of modern methods complete the understanding of microbial processes during the conversion of must to wine.This broad range of topics about the biology of the microbes involved in the vinification process could be provided in one book only because of the input of many experts from different wine-growing countries.

The use of non-Saccharomyces yeast species is currently a biotechnology trend in enology for which they are being broadly used to improve the sensory profile of wines because they affect aroma, color, and mouthfeel. They have become a powerful biotool to modulate the influence of global warming on grape varieties, helping to maintain the acidity, decrease the alcoholic degree, stabilize wine color, and increase freshness. In cool climates, some non-Saccharomyces can promote demalication or color stability by the formation of stable derived pigments. Additionally, non-Saccharomyces yeasts open new possibilities in biocontrol for removing spoilage yeast and bacteria or molds that can produce and release mycotoxins and, thereby, help in reducing applied SO2 levels.
