Winemaking as a form of food preseIVation is as old as civilization. Wine has been an integral component of people's daily diet since its discovery and has also played an important role in the development of society, reli gion, and culture. We are currently drinking the best wines ever produced. We are able to do this because of our increased understanding of grape growing, biochemistry and microbiology of fermentation, our use of ad vanced technology in production, and our ability to measure the various major and minor components that comprise this fascinating beverage. Historically, winemakers succeeded with slow but gradual improvements brought about by combinations of folklore, obseIVation, and luck. How ever, they also had monumental failures resulting in the necessity to dis pose of wine or convert it into distilled spirits or vinegar. It was assumed that even the most marginally drinkable wines could be marketed. This is not the case for modern producers. The costs of grapes, the technology used in production, oak barrels, corks, bottling equipment, etc. , have in creased dramatically and continue to rise. Consumers are now accustomed to supplies of inexpensive and high-quality varietals and blends; they con tinue to demand better. Modern winemakers now rely on basic science and xvi Preface xvii the systematic application of their art to produce products pleasing to the increasingly knowledgeable consumer base that enjoys wine as part of its civilized society.

Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were: 1. the dependence of scientific progress in biology on the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete that it is difficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be just as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a way that made description, as applied to plant material, complete in itself with little need to consult other publications. Contributing authors have attempted to follow these guidelines in this New Series of volumes.

The purpose of this book is to present procedures and guidelines for chemical analysis and tests of grapes, grape juice and wine, with the results acting as a tool to aid decision making throughout the winemaking process.

Chemical physical and sensory methods for analysing grapes and wine

Red Wine Technology is a solutions-based approach on the challenges associated with red wine production. It focuses on the technology and biotechnology of red wines, and is ideal for anyone who needs a quick reference on novel ways to increase and improve overall red wine production and innovation. The book provides emerging trends in modern enology, including molecular tools for wine quality and analysis. It includes sections on new ways of maceration extraction, alternative microorganisms for alcoholic fermentation, and malolactic fermentation. Recent studies and technological advancements to improve grape maturity and production are also presented, along with tactics to control PH level.This book is an essential resource for wine producers, researchers, practitioners, technologists and students. - Winner of the OIV Award 2019 (Category: Enology), International Organization of Vine and Wine - Provides innovative technologies to improve maceration and color/tannin extraction, which influences color stability due to the formation of pyranoanthocyanins and polymeric pigments - Contains deep evaluations of barrel ageing as well as new alternatives such as microoxigenation, chips, and biological ageing on lees - Explores emerging biotechnologies for red wine fermentation including the use of non-Saccharomyces yeasts and yeast-bacteria coinoculations, which have effects in wine aroma and sensory quality, and also control spoilage microorganisms

In the beginning, for me, winemaking was a romanticized notion of putting grape juice into a barrel and allowing time to perform its magic as you sat on the veranda watching the sunset on a Tuscan landscape. For some small wineries, this notion might still ring true, but for the majority of wineries commercially producing quality wines, the reality of winemaking is far more complex. The persistent evolution of the wine industry demands continual advan- ments in technology and education to sustain and promote quality winem- ing. The sciences of viticulture, enology, and wine chemistry are becoming more intricate and sophisticated each year. Wine laboratories have become an integral part of the winemaking process, necessitating a knowledgeable staff possessing a multitude of skills. Science incorporates the tools that new-age winemakers are utilizing to produce some of the best wines ever made in this multibillion dollar trade. A novice to enology and wine chemistry can find these subjects daunting and intimidating. Whether you are a home winemaker, a new winemaker, an enology student, or a beginning-to-intermediate laboratory technician, p- ting all the pieces together can take time. As a winemaker friend once told me, “winemaking is a moving target. ” Introduction to Wine Laboratory Practices and Procedures was written for the multitude of people entering the wine industry and those that wish to learn about wine chemistry and enology.
