R. Stevens – författare

Some ten years. have passed since the publication of the first edition of Malting and Brewing Science, a period of many changes. As before, this edition is an aid to teaching, particularly the MSc course in Brewing Science at Birmingham University, but it is also aimed at the requirements of other students of the science of malting and brewing throughout the world. In general, technological aspects are covered more fully in this new edition, although not malting and brewing practices that are exclusive to Britain. Nevertheless, the amount of technological information available is too great to be comprehensively covered iln one book. Scientific principles and infor­ mation receive more attention, but for details of analytical procedures reference should be made to the most recently published material of the Ameri­ can Society of Brewing Chemists, the European Brewery Convention and the Institute of Brewing. The new edition appears as two volumes because a single one would be inconveniently bulky. The first volume outlines the entire process and leads from barley, malting and water to the production of sweet wort. In the second volume there are chapters on hops and hop products, production of hopped wort, fermentation,yeast biology and all aspects of beer qualities and treatment. Decisions about the units of measurement proved difficult; metric units commonly used in the Industry are given and in parentheses are equivalents in degrees Fahrenheit, Imperial measures and UK barrels. Considerable information on equivalents is given in a special section in each volume.

What is best in life? Cats and the Internet, of course! And when you put thetwo together, you have the third collection of Rich Stevens’ long-runningand pioneering pixel comic, Diesel Sweeties! Watch as the DieselSweeties gang explores the two oft-debated questions in life: “Why ismy internet not working?” and “What does the damn cat wantnow?” For anyone struggling to remember the official ranking of socialmedia (Hint: the acronym is GIFT) or wondering what it means to ship RoombaxCat,this collection is a godsend. Or, at the very least, a “send.”

Brewing is one of the oldest and most complex technologies in food and beverage processing. Its success depends on blending a sound understanding of the science involved with an equally clear grasp of the practicalities of production. Brewing: science and practice provides a comprehensive and authoritative guide to both of these aspects of the subject.After an initial overview of the brewing process, malts, adjuncts and enzymes are reviewed. A chapter is then devoted to water, effluents and wastes. There follows a group of chapters on the science and technology of mashing, including grist preparation. The next two chapters discuss hops, and are followed by chapters on wort boiling, clarification and aeration. Three chapters are devoted to the important topics of yeast biology, metabolism and growth. Fermentation, fermentation technologies and beer maturation are then reviewed, followed by a consideration of native African beers. After a discussion of brewhouses, the authors consider a number of safety and quality issues, including beer microbiology and the chemical and physical properties of beer, which contribute to qualities such as flavour. A final group of chapters cover packaging, storage, distribution and the retail handling of beer.Based on the authors' unrivalled experience in the field, Brewing: science and practice is a standard work for the industry.A detailed account of all stages of the brewing processSafety and quality issues are discussed, including the chemical and physical properties of beer and beer microbiologyA strong partnership of the science and the practicalities of production ensures this book is a primary reference
