Book Description
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.

Book Description
The ancient beverage wine is the result of the fermentation of grape must. This n- urally and fairly stable product has been and is being used by many human societies as a common or enjoyable beverage, as an important means to improve the quality of drinking water in historical times, as therapeutical agent, and as a religious symbol. During the last centuries, wine has become an object of scientific interest. In this respect different periods may be observed. At first, simple observations were recorded, and subsequently, the chemical basis and the involvement of microorg- isms were elucidated. At a later stage, the scientific work led to the analysis of the many minor and trace compounds in wine, the detection and understanding of the biochemical reactions and processes, the diversity of microorganisms involved, and the range of their various activities. In recent years, the focus shifted to the genetic basis of the microorganisms and the molecular aspects of the cells, including metabolism, membrane transport, and regulation. These different stages of wine research were determined by the scientific methods that were known and available at the respective time. The recent “molecular” approach is based on the analysis of the genetic code and has led to significant results that were not even imaginable a few decades ago. This new wealth of information is being presented in the Biology of Microorganisms on Grapes, in Must, and in Wine.

Book Description
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.

Book Description
HANDBOOK OF FRUITS AND FRUIT PROCESSING SECOND EDITION Fruits are botanically diverse, perishable, seasonal, and predominantly regional in production. They come in many varieties, shapes, sizes, colors, flavors, and textures and are an important part of a healthy diet and the global economy. Besides vitamins, minerals, fibers, and other nutrients, fruits contain phenolic compounds that have pharmacological potential. Consumed as a part of a regular diet, these naturally occurring plant constituents are believed to provide a wide range of physiological benefits through their antioxidant, anti-allergic, anti-carcinogenic, and anti-inflammatory properties. Handbook of Fruits and Fruit Processing distils the latest developments and research efforts in this field that are aimed at improving production methods, post-harvest storage and processing, safety, quality, and developing new processes and products. This revised and updated second edition expands and improves upon the coverage of the original book. Some highlights include chapters on the physiology and classification of fruits, horticultural biochemistry, microbiology and food safety (including HACCP, safety and the regulation of fruits in the global market), sensory and flavor characteristics, nutrition, naturally present bioactive phenolics, postharvest physiology, storage, transportation, and packaging, processing, and preservation technologies.
