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
