Brewing Microbiology

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.

Brewing Microbiology discusses the microbes that are essential to successful beer production and processing, and the ways they can pose hazards in terms of spoilage and sensory quality. The text examines the properties and management of these microorganisms in brewing, along with tactics for reducing spoilage and optimizing beer quality. It opens with an introduction to beer microbiology, covering yeast properties and management, and then delves into a review of spoilage bacteria and other contaminants and tactics to reduce microbial spoilage. Final sections explore the impact of microbiology on the sensory quality of beer and the safe management and valorisation of brewing waste. Examines key developments in brewing microbiology, discussing the microbes that are essential for successful beer production and processing Covers spoilage bacteria, yeasts, sensory quality, and microbiological waste management Focuses on developments in industry and academia, bringing together leading experts in the field

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.

Brewing: Science and practice updates and revises the previous work of this distinguished team of authors, producing what is the standard work in its field. The book covers all stages of brewing from raw materials, including the chemistry of hops and the biology of yeasts, through individual processes such as mashing and wort separation to packaging, storage and distribution. Key quality issues are discussed such as flavour and the chemical and physical properties of finished beers.

Highly recommended for anyone involved in the microbiology of brewing, this book surveys the most recent discoveries in brewing microbiology with an emphasis on omics techniques and other modern technologies. Covers applications from barley growth and malting to yeast management, strain selection, fermentation control, and quality assurance.

Brewing is designed for those involved in the malting, brewing, and allied industries who have little or no formal training in brewing science. While some elementary knowledge of chemistry and biology is necessary, the book clearly presents the essentials of brewing science and its relationship to brewing technology. Brewing focuses on the principles and practices most central to an understanding of the brewing process, including preparation of malt, hops, and yeast; the fermentation process; microbiology and contaminants; and finishing, packaging, and flavor. The second edition gives more emphasis to engineering and technological aspects, with the three new chapters on water, engineering and analysis. Brewing, Second Edition, is both a basic text for traditional college, short, and extension courses in brewing science, and a basic reference for anyone in the brewing industry.

The Czech Republic is one of the motherlands of beer culture – beers of the pilsner brewing tradition and the aromatic Saaz hops are famous the world over. Brewing technicians and scientists from the Czech Republic have an excellent reputation and are constantly seeking an exchange and discussion of their research findings on the international scene. And the team of authors around Professor Basařová are all experienced technicians and scientists with a wealth of international experience. "The Comprehensive Guide to Brewing" is a unique groundwork for brewing technicians which deals with all subject areas, from the raw materials to packaging. It also conveys advanced knowledge of the fundamentals of brewing research. Compulsory reading for anyone who wishes to gain in-depth knowledge of brewing technology.
