Beer is the only detailed book that specifically addresses the science of beer quality. It explores the quality attributes of beer as well as the various impacts on and perception of beer quality. It includes expert insights based on real-world experience. This book details, with extensive referencing, the research that has been devoted to beer and beer quality. It is the first book to approach beer in this way and comprises an essential reference for anyone seeking an authoritative account of the science of beer appearance, flavor, stability and wholesomeness. Chapters discuss beer foam and how to achieve a suitable head; beer flavour and its instability; colloidal stability of beer; microbiological stability of beer; beer gushing; beer color; and the health aspects of beer. This book will be of interest to employees on the technical production side of the alcoholic beverage industry; students studying the subject; people involved in related and associated biotechnology industries; people from the brewing industry; and academic researchers. * The only detailed book that specifically addresses the science of beer quality * Addresses the various impacts on and perception of beer quality * Includes expert insights based on real-world experience

Much has happened in the brewing industry since the last edition of this book was published in 1996. In particular, there has been substantial con solidation of larger brewing companies as major multinational concerns, and at the other end of the spectrum the microbrewing scene in various parts of the world has become established as a sustainable enterprise. For those involved in the scientific and technical aspects of fermented bever age production the changes have been no less daunting. The complete genome sequence of Saccharomyces cerevisiae has been determined and studies are underway in numerous laboratories throughout the world to unravel the expression of the genome (transcriptomics and proteomics) and understand exactly "how a yeast works. " This will undoubtedly con tribute to our understanding of yeast fermentation and flavor generation in a revolutionary way because it will enable the simultaneous monitor ing of all genes in the organism during the fermentation. In Chapters 2 and 3 of this volume Colin Slaughter and John Hammond bring the reader up-to-date in this rapidly moving area and cover the remarkable achievements of modern biochemistry and molecular biology. lain Campbell has also revised the systematics of culture and wild yeasts in Chapter 7. The other major technical change since the last edition of this book is the introduction of molecular characterization and detection of microor ganisms based largely, but not exclusively, on the polymerase chain reac tion (PCR) for amplification of specific DNA fragments.

A History of Beer and Brewing provides a comprehensive account of the history of beer. Research carried out during the last quarter of the 20th century has permitted us to re-think the way in which some ancient civilizations went about their beer production. There have also been some highly innovative technical developments, many of which have led to the sophistication and efficiency of 21st century brewing methodology. A History of Beer and Brewing covers a time-span of around eight thousand years and in doing so: * Stimulates the reader to consider how, and why, the first fermented beverages might have originated * Establishes some of the parameters that encompass the diverse range of alcoholic beverages assigned the generic name 'beer' * Considers the possible means of dissemination of early brewing technologies from their Near Eastern origins The book is aimed at a wide readership particularly beer enthusiasts. However the use of original quotations and references associated with them should enable the serious scholar to delve into this subject in even greater depth.

During the latter part of the last century and the early years of this century, the microbiology of beer and the brewing process played a central role in the development of modern microbiology. An important advance was Hansen's development of pure culture yeasts for brewery fermentations and the recognition of different species of brewing and wild yeasts. The discovery by Winge of the life cycles of yeasts and the possibilities of hybridization were among the first steps in yeast genetics with subsequent far-reaching consequences. Over the same period the contaminant bacteria of the fermentation industries were also studied, largely influenced by Shimwell's pioneering research and resulting in the improvement of beer quality. Towards the end of the century, the influence of brewing microbiology within the discipline as a whole is far less important, but it retains an essential role in quality assurance in the brewing industry. Brewing microbiology has gained from advances in other aspects of microbiology and has adopted many of the techniques of biotechnology. Of particular relevance are the developments in yeast genetics and strain improvement by recombinant DNA techniques which are rapidly altering the way brewers view the most important microbiological components of the process: yeast and fermentation.
