The Hop Grower's Handbook
Author: Laura Ten Eyck
Publisher: Chelsea Green Publishing
ISBN: 1603585567
Category : Technology & Engineering
Languages : en
Pages : 290
Book Description
With information on siting, planting, tending, harvesting, processing, and brewing It’s hard to think about beer these days without thinking about hops. The runaway craft beer market’s convergence with the ever-expanding local foods movement is helping to spur a local-hops renaissance. The demand from craft brewers for local ingredients to make beer—such as hops and barley—is robust and growing. That’s good news for farmers looking to diversify, but the catch is that hops have not been grown commercially in the eastern United States for nearly a century. Today, farmers from Maine to North Carolina are working hard to respond to the craft brewers’ desperate call for locally grown hops. But questions arise: How best to create hop yards—virtual forests of 18-foot poles that can be expensive to build? How to select hop varieties, and plant and tend the bines, which often take up to three years to reach full production? How to best pick, process, and price them for market? And, how best to manage the fungal diseases and insects that wiped out the eastern hop industry 100 years ago, and which are thriving in the hotter and more humid states thanks to climate change? Answers to these questions can be found in The Hop Grower’s Handbook—the only book on the market about raising hops sustainably, on a small scale, for the commercial craft beer market in the Northeast. Written by hop farmers and craft brewery owners Laura Ten Eyck and Dietrich Gehring, The Hop Grower’s Handbook is a beautifully photographed and illustrated book that weaves the story of their Helderberg Hop Farm with the colorful history of New York and New England hop farming, relays horticultural information about the unusual hop plant and the mysterious resins it produces that give beer a distinctively bitter flavor, and includes an overview of the numerous native, heirloom, and modern varieties of hops and their purposes. The authors also provide an easy-to-understand explanation of the beer-brewing process—critical for hop growers to understand in order be able to provide the high-quality product brewers want to buy—along with recipes from a few of their favorite home and micro-brewers. The book also provides readers with detailed information on: • Selecting, preparing, and designing a hop yard site, including irrigation; • Tending to the hops, with details on best practices to manage weeds, insects, and diseases; and, • Harvesting, drying, analyzing, processing, and pricing hops for market. The overwhelming majority of books and resources devoted to hop production currently available are geared toward the Pacific Northwest’s large-scale commercial growers, who use synthetic pesticides, fungicides, herbicides, and fertilizers and deal with regionally specific climate, soils, weeds, and insect populations. Ten Eyck and Gehring, however, focus on farming hops sustainably. While they relay their experience about growing in a new Northeastern climate subject to the higher temperatures and volatile cycles of drought and deluge brought about by global warming, this book will be an essential resource for home-scale and small-scale commercial hops growers in all regions.

Soils, Plant Growth and Crop Production - Volume II
Author: Willy H. Verheye
Publisher: EOLSS Publications
ISBN: 1848263686
Category : Crops
Languages : en
Pages : 454
Book Description
Soils, Plant Growth and Crop Production is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Plants, and crops in particular, grow and develop through the uptake of water and nutrients by the root system in soils and their transformation into biomass through processes governed by photosynthesis. The quality and amount of products harvested from this biomass depend largely on the intrinsic properties of the soil, i.e. the moisture and nutrients made available for uptake by the roots. These volumes describe in a synthetic form the impact of the most important soil properties on general agronomy, crop production, cultivation methods, and yields, including the specific management aspects which take away some production constraints. Changes in general agronomy as a result of plant breeding, climatic change and competition between newly introduced crops are discussed. The three volumes with contributions from distinguished experts in the field discusses about soils, plant growth and crop production in several related topics. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

For The Love of Hops
Author: Stan Hieronymus
Publisher: Brewers Publications
ISBN: 1938469038
Category : Cooking
Languages : en
Pages : 344
Book Description
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.”

Diagnosing Hemp and Cannabis Crop Diseases
Author: Shouhua Wang
Publisher: CABI
ISBN: 1789246075
Category : Science
Languages : en
Pages : 306
Book Description
Hemp and cannabis, both belonging to Cannabis sativa, have emerged as some of the most valuable crops because of their multiple functionalities - industrial, medicinal, and recreational uses. Like all other crops, they are at risk of diseases and pests. In certain cases, an entire hemp field can fail due to unexpected disease. As a new and highly regulated crop, research on Cannabis crop diseases is scarce, and the science of plant diagnostics is not well covered in the literature. Taking hemp/cannabis as a model crop, the book illustrates how to diagnose a disease problem and how to manage it effectively. It presents real disease cases encountered during crop production, and explains methods of diagnosis, both in the field and in the lab, in order to find out the cause(s).
