Consumers, regulators, and the food industry increasingly require that foods comply not only with label descriptions of food content, but also with information regarding the food's origin. For example, the wine industry has a long history of labeling wines based on varietal, regional, or age (vintage)-related properties. However, regulatory agencies are now beginning to require methods to confirm this label information. Food retailers are also facing voluntary or mandatory labeling requirements that will indicate regional or country-of-origin, species and/or varietal information. As a result, development of reliable analytical methods to confirm the authenticity of the label information is needed. This book presents the latest research on food and wine authentication. The chapters are authored by leading international scientists whose research focuses on the development and application of analytical methodologies used for the authentication of food and beverages.

It is well established that certain strains of yeasts are suitable for transforming grape sugars into alcohol, while other yeast strains are not suitable for grape fermentations. Recent progress has clearly demonstrated that the sensory profile of a wine is characteristic of each vine cultivated, and the quality and technological characteristics of the final product varies considerably due to the strains which have performed and/or dominated the fermentation process. Because of their technological properties, wine yeast strains differ significantly in their fermentation performance and in their contribution to the final bouquet and quality of wine, such as useful enzymatic activities and production of secondary compounds related both to wine organoleptic quality and human health. The wine industry is greatly interested in wine yeast strains with a range of specialized properties, but as the expression of these properties differs with the type and style of wine to be made, the actual trend is in the use of selected strains, which are more appropriate to optimize grape quality. Additionally, wine quality can be influenced by the potential growth and activity of undesirable yeast species, considered spoilage yeasts, which cause sluggish and stuck fermentation and detrimental taste and aroma in the wine.

The primary text since 1997 for scores of universities and winemakers in a dozen countries, Concepts in Wine Chemistry, by physical chemist and winemaker Yair Margalit, is now totally revised and updated, making it, in editor James Crumb's, Ph.D. words, "the broadest, most meticulous book on the topic in print." Under study here is the basic and advanced chemistry behind the practical concepts of winemaking: must and wine composition, fermentation, phenolic compounds, aroma and flavor, oxidation and wine aging, oak products, sulfur dioxide, cellar processes and wine faults. Dr. Margalit also gives the biochemist's slant on the question: is wine good for you? New to this edition are the latest discoveries that have changed winemaking and brought about new techniques and innovations, including advances in the understanding of volatile esters, red wine phenolic compounds, yeast and factors affecting fermentation, flavour compounds and red-wine colour characteristics, technical properties of "naturally fermented" wines, pesticide use, malolactic fermentation, and the use of wood.

Understanding Wine Technology has become the most favoured book of many students. This book is aimed at the person with no formal scientific training, yet who is interested in the science behind wine and wants to know the mechanism behind the complex transformations that take place. Scientific terminology has been kept to a minimum and an attempt has been made to use everyday words and phrases. Indeed, there are places where the scientist might raise the eyebrows, places where perhaps science has had to give way to an easy understanding of a complex principle. In this fourth edition Nicolas Quille, a well-qualified and widely-experienced French winemaker working in Oregon USA has brought the information up-to-date so that this book remains the mainstay for those who are studying for the Diploma of the WSET or for membership of the Institute of Masters of Wine. The text has also been expanded to include more information on the making of the major styles of the wines of the world, which should be of interest to those who are not engaged in study, but who have an enquiring mind and therefore want to know the mechanisms behind their production. Hugh Johnson writes in the Foreword: I'm not sure whether to call this book a primer, a memory-jogger or a lifesaver. Which it is depends on the reader. For WSET students it is essentially the first, then the second. For people like me it is the third- than rather belatedly the first. What we all need is a crisp exposition of how wine is made and why, easy to refer to when a funny smell appears, to cover the physics, natural history, legislation and finally the appreciation of wine. David's first edition has been my stand-by for years. I have my Peynaud, my Amerine & Joslyn, my Michael Schuster for going deeper in certain areas where necessary, but I wouldn't be without Bird in the hand. This fourth edition adds freshly-focused insight into the production of the principal styles of the wines of the world, making it equally interesting for those who are simply lovers of wine and for those who are serious students of the Master of Wine examination. New concepts such as Orange, organic, biodynamic and 'natural' wines have been added to the public's vocabulary - leaving many baffled and curious. Modern food legislation adds another obstacle course for the winemaker to negotiate. The detailed explanation of the mysteries of Hazard Analysis make this book particularly useful for wineries that are faced with the new problems of food safety legislation. Essentially, though, this is the classic Bird, much updated from the third edition and available once more to ease the pangs of students young and old.

As the wine industry has experienced a period of rapid global expansion, there is a renewed emphasis on quality and consistency even within the small winery industry.

Following the enormous, decade-long success of his best-selling Winery Technology and Operations, physical chemist and winemaker Yair Margalit comes out with the successive, Concepts in Wine Technology, fully updated and revised to meet the advances of modern winemaking. Among the extended topics are fermentation, skin contact, acid balance, phenolics, bottling, the use of oak and quality control. He begins in the vineyard discussing proper maturation, soil and climate, bunch health, vineyard disease states and grape varieties. Next he tackles the pre-harvest with a careful look at vineyard management and preparing the winery for harvest. Dr. Margalit then outlines the entire process of harvesting, from destemming, crushing and skin contact as it applies to both red and white grapes to pressing, must correction and temperature control. Fermentation is examined fully and includes a lengthy look at the factors affecting malo-lactic fermentation and its pros and cons. There is a huge chapter on cellar operations that deals with racking, stabilization, fining, filtration, blending and maintaining winery hardware, followed by sections on barrelling and bottling. The final chapter pulls together the more general aspects of wine technology, covering sulphur-dioxides, different forms of wine spoilage and ways to ward them off, legal regulations and, one of the most important and enigmatic compounds in wine, phenolics.

The first book to focus on the role of glass as a material of critical importance to the wine industry For centuries glass has been the material of choice for storing, shipping, and sipping wine. How did that come to pass, and why? To what extent have glassmaking and wine making co-evolved over the centuries? The first book to focus on the role of glass as a material of critical importance to the wine industry, The Glass of Wine answers these and other fascinating questions. The authors deftly interweave compelling historical, technical, and esthetic narratives in their exploration of glass as the vessel of choice for holding, storing, and consuming wine. They discuss the traditions informing the shapes and sizes of wine bottles and wine glasses, and they demystify the selection of the "right glass" for red versus white varietals, as well as sparkling and dessert wines. In addition, they review the technology of modern glassmaking and consider the various roles glass plays in wineries especially in the enologist's laboratory. And they consider the increasing use of aluminum and polymer containers and its potential impact on the central role of glass as the essential material for wine appreciation. * The first book focusing on the role of glass and its central importance to the wine industry * Written by a glass scientist at UC Davis, home of the premier viticulture and enology program in North America * Interlards discussions of the multi-billion-dollar glass and wine industries with valuable technical insights for scientists, engineers, and wine enthusiasts alike * Illustrates the wide spectrum of bottles, carafes, decanters, and drinking glasses with an abundance of exquisite full-color photos Both an authoritative guide and a compelling read, The Glass of Wine tells the story of the centuries-old marriage between an endlessly fascinating material and a celebrated beverage.

The aim of this book is to show how wine tourism can be used as a model for sustainable economic development, driving economic growth and social development in some locations. It will explore the interaction between tourism and viticulture in wine tourism destinations, while also explaining some of the repercussions of these activities. This book covers various topics including regional development, environmental management, sustainable viticulture, quality management in wineries and wine tourism routes among others. Wine tourism, which combines two important yet distinct economic activities (i.e., tourism and viticulture), has recently emerged as a new tourism product driven by tourists' search for new experiences and wineries' need to diversify their businesses and seek new revenue streams to boost sales. This new form of tourism, which typically takes place in rural areas and which combines wine production with tourist activities, is becoming important for such regions by providing a complementary income source. It provides a model for sustainable economic development for these regions, which for various reasons may otherwise struggle to develop. Featuring cases and business implications from various locations, this book provides an important source of knowledge-both theoretical and practical-suitable to academics, scholars, researchers, and practitioners in the tourism sector and the wine industry.

Drawing on over 200 interviews and visits with winery owners, executives and managers in five countries, industry experts across marketing and supply chain management examine successful marketing frameworks as they apply to growers, wineries, distributors, and retailers. Combined with contemporary expertise in brand management, sales, research, social media, this book explores exciting and effective business practices and offers contemporary marketing ideas that will help wineries thrive.

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.

Over the past several decades, consumer interest in the fine vintage wines produced by small "boutique" vintners across the United States has grown to rival that of many European estates. This attention continues to intensify, especially for the truly good wines that are reasonably priced. Consumers are, however, unforgiving especially wine enthusiasts. Second-class wines do not succeed just because a vintner is new. The methods and controls essential to vintners in the production and marketing of top-grade wines have advanced. This second edition of Winemaking has updated and, in some cases, completely revised the material associated with these disciplines. Fine wine is much like other art forms, as it is the infinite variability of factors pertaining to the subject that renders it so complex-and able to attract buyer's attention. Hundreds of different vine varieties are cultivated around the world, and no doubt an even greater number of fruit and berry cultivars. Andwith the addition of such factors as terroir (soil and climate attributes) changing every vintage season, varied vineyard cultivation and harvesting techniques, advancing production technology, dynamic markets, and overall operational philosophy, one can easily understand the enormous breadth and depth of variation that exists. This diversity generates an unimaginable number of different wine possibilities."

Science and Technology of Fruit Wine Production includes introductory chapters on the production of wine from fruits other than grapes, including their composition, chemistry, role, quality of raw material, medicinal values, quality factors, bioreactor technology, production, optimization, standardization, preservation, and evaluation of different wines, specialty wines, and brandies. Wine and its related products have been consumed since ancient times, not only for stimulatory and healthful properties, but also as an important adjunct to the human diet by increasing satisfaction and contributing to the relaxation necessary for proper digestion and absorption of food. Most wines are produced from grapes throughout the world, however, fruits other than grapes, including apple, plum, peach, pear, berries, cherries, currants, apricot, and many others can also be profitably utilized in the production of wines. The major problems in wine production, however, arise from the difficulty in extracting the sugar from the pulp of some of the fruits, or finding that the juices obtained lack in the requisite sugar contents, have higher acidity, more anthocyanins, or have poor fermentability. The book demonstrates that the application of enzymes in juice extraction, bioreactor technology, and biological de-acidification (MLF bacteria, or de-acidifying yeast like schizosaccharomyces pombe, and others) in wine production from non-grape fruits needs serious consideration.

One of the main concerns of the food industry is the need for high-quality fresh fruits and fruit products with good sensory quality, long shelf life, and high nutritional value. To meet these demands, new processing technologies are under investigation and development. Advances in Fruit Processing Technologies incorporates fundamentals in food processing as well as the advances made in recent years to improve final product quality. With contributions from a panel of international researchers who present a blend of classical and emerging technologies, the book explores: Ozone, ultrasound, irradiation, pulsed electric field, vacuum frying, and high-pressure processing Ultraviolet and membrane processing Enzymatic maceration, freeze concentration, and refrigeration The effect of processing on sensory characteristics and nutritional value New trends in modified atmosphere packaging The use of fruit juices as a vehicle for probiotic microorganisms Prebiotic oligosaccharides as an alternative for dairy products Incorporating a series of case studies on the application of various technologies, the book reviews their advantages, limitations, successes, and failures. The contributors also examine the implications of food processing technologies on waste production, energy use, and resource requirements. This comprehensive survey of methods for optimizing fruit quality is an ideal resource for those in the fruit and vegetable industry looking for innovations that can improve efficiency, reduce waste, and cut costs.
