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.

This book is for anyone who is a practising brewer, works in the brewing industry, or has a strong interest in brewing techniques, procedures and know-how. With topics ranging from the ingredients to formulation to operation of the brewery, this book acts as a handy guide for the topic of brewing. With each chapter presenting detailed information, tips and practical pitfalls, there is enough and more to equip the reader with a deeper and broader understanding of the industry.

Ancient brewing traditions and techniques have been passed generation to generation on farms throughout remote areas of northern Europe. With these traditions facing near extinction, author Lars Marius Garshol set out to explore and document the lost art of brewing using traditional local methods. Equal parts history, cultural anthropology, social science, and travelogue, this book describes brewing and fermentation techniques that are vastly different from modern craft brewing and preserves them for posterity and exploration. Learn about uncovering an unusual strain of yeast, called kveik, which can ferment a batch to completion in just 36 hours. Discover how to make keptinis by baking the mash in the oven. Explore using juniper boughs for various stages of the brewing process. Test your own hand by brewing recipes gleaned from years of travel and research in the farmlands of northern Europe. Meet the brewers and delve into the ingredients that have kept these traditional methods alive. Discover the regional and stylistic differences between farmhouse brewers today and throughout history.

It is difficult to believe that at one time hops were very much the marginalized ingredient of modern beer, until the burgeoning craft beer movement in America reignited the industry's enthusiasm for hop-forward beer. The history of hops and their use in beer is long and shrouded in mystery to this day, but Stan Hieronymous has gamely teased apart the many threads as best anyone can, lending credence where due and scotching unfounded claims when appropriate. It is just one example of the deep research through history books, research articles, and first-hand interviews with present-day experts and growers that has enabled Stan to produce a wide-ranging, engaging account of this essential beer ingredient. While they have an exalted status with today's craft brewers, many may not be aware of the journey hops take to bring them, neatly baled or pressed into blocks and pellets, into the brewhouse. Stan paints a detailed and, at times, personal portrait of the life of hops, weaving technical information about hop growing and anatomy with insights from families who have been running their hop farms for generations. The author takes the reader on a tour of the main growing regions of central Europe, where the famous landrace varieties of Slovenia, the Czech Republic, and Germany originate, to England and thence to North America, and latterly, Australia and New Zealand. Growing hops and supplying the global brewing industry has always been a hard-nosed business, and Stan presents statistics on yields, acreage, wilt and other diseases, interspersed with words from the farmers themselves that illustrate the challenges and uncertainties hop growers face. Along the way, Stan gives details about some of the most well-known varieties—Saaz, Hallertau, Tettnang, Golding, Fuggle, Cluster, Cascade, Willamette, Citra, Amarillo, Nelson Sauvin, and many others—and their history of use in the Old World and New World. The section culminates in a catalog of 105 hop varieties in use today, with a brief description of character and vital statistics for each. Of course, the art and science of using hops in making beer is not forgotten. Once the hops have been harvested, processed, and delivered to the brewery, they can be used in myriad ways. The author moves from the toil of the hop gardens to that of the brewhouse, again presenting a blend of history and present-day interviews and research articles to explain alpha acids, beta acids, bitterness, harshness, smoothness, and the deterioration of bittering flavors over time. Perception is all important when discussing bitterness, and the author touches on genetics, evolution, the vagaries of individuals' perceptions of bitterness, and changing tastes, such as the “lupulin shift.” The meaning of the international bitterness unit, or IBU, is not always properly understood and here Stan lays out a brief history of how the IBU came to be and an appreciation of the many variables affecting utilization in the boil and final bitterness in beer. Adding hops is not as simple as it sounds, and Stan's research illustrates that if you ask ten brewers about something you will get eleven opinions. Early additions, late additions, continuous hopping, first wort hopping, and hop bursting are all discussed with a healthy dose of pragmatic wisdom from brewers and a pinch of chemistry. There then follows an entire chapter devoted to the druidic art of dry hopping, following its commonplace usage in nineteenth-century England to the modern applications found in today's US craft brewing scene. The author uncovers hop plugs, hop coffins, and the “pendulum method,” along with the famous hop rocket and hop torpedo used by some of America's leading craft breweries. Every brewer has their dry hopping method and, gratifyingly, many are happy to share with the author, making this chapter a great source for inspiration and ideas. Many of the brewers the author interviewed were also happy to share recipes. There are 16 recipes from breweries in America, Belgium, Czech Republic, Denmark, England, Germany, and New Zealand. These not only present delicious beers but give some insight into how professional brewers design their recipes to get the most out of their hops. As always, Stan imparts wisdom in an engaging and accessible fashion, making this an amazing compendium on “every brewer's favorite flower.”

This is a guide to the technical aspects of brewing beer. This book covers a wide range of topics, including the properties of ingredients such as barley and hops, the process of malting, the different types of fermentation, and the management of beer in cellars. It also includes practical advice on calculating water volume, controlling temperature, and managing the brewing process from start to finish.

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.

Water is arguably the most critical and least understood of the foundation elements in brewing. For many brewers used to choosing from a wide selection of hops and grain, water seems like an ingredient for which they have little choice but to accept what comes out of their faucet. But brewers in fact have many opportunities to modify their source water or to obtain mineral-free water and build their own brewing water from scratch. Much of the relevant information can be found in texts on physical and inorganic chemistry or water treatment and analysis, but these resources seldom, if ever, speak to brewers. Water: A Comprehensive Guide for Brewers takes the mystery out of water's role in the brewing process. This book is not just about brewing liquor. Whether in a brewery or at home, water is needed for every part of the brewing process: chilling, diluting, cleaning, boiler operation, wastewater treatment, and even physically pushing wort or beer from one place to another. The authors lead the reader from an overview of the water cycle and water sources, to adjusting water for different beer styles and brewery processes, to wastewater treatment. It covers precipitation, groundwater, and surface water, and explains how municipal water is treated to make it safe to drink but not always suitable for brewing. The parameters measured in a water report are explained, along with their impact on the mash and the final beer. Understand ion concentrations, temporary and permanent hardness, and pH. The concept of residual alkalinity is covered in detail and the causes of alkalinity in water are explored, along with techniques to control alkalinity. Ultimately, residual alkalinity is the major effector on mash pH, and this book addresses how to predict and target a specific mash pH—a key skill for any brewer wishing to raise their beer to the next level. But minerals in brewing water also determine specific flavor attributes. Ionic species important to beer are discussed and concepts like the sulfate-to-chloride ratio are explained. Examples illustrate how to tailor your brewing water to suit any style of beer. To complete the subject, the authors focus on brewery operations relating to source water treatment, such as the removal of particulates, dissolved solids, gas and liquid contaminants, organic contaminants, chlorine and chloramine, and dissolved oxygen. This section considers the pros and cons of various technologies, including membrane technologies such as filtration, ion-exchange systems, and reverse osmosis.
