More than 150 years after Louis Pasteur attributed fermentation to a living organism, the field of wine microbiology and chemistry is vibrant with discovery. The last decade alone has seen great strides in our understanding of the biochemistry involved in vinification. In this new edition of his classic text, Yair Margalit gives the complete and current picture of the basic and advanced science behind these processes, making the updated Concepts in Wine Chemistry the broadest and most meticulous book on the topic in print. Organized to track the sequence of the winemaking process, chapters cover must and wine composition, fermentation, phenolic compounds, wine oxidation, oak products, sulfur dioxide, cellar processes, and wine defects. Margalit ends with chapters detailing the regulations and legal requirements in the production of wine, and the history of wine chemistry and winemaking practices of old.

This is the companion book to the author's best selling Concepts In Wine Chemistry. It is a successor to his original Winery Technology & Operations. Since the author published his first book in 1990, he has shifted much of his time from research and teaching to operating his own small winery and consulting world-wide with other winemakers. Thus, this new text has a very practical and applied science character. In addition there have been significant discoveries and technological advances in winemaking since the original text. The enlarged sections on fermentation, skin contact, acid balance, the use of oak, phenolics and quality control reflect and expand upon the original text. This is a "how-to" book, organized in the sequence of the processes a winemaker faces when confronted with the rapid challenge of converting fresh grapes into good wine. As the author points out, the grapes will make wine by themselves due to natural biological and chemical processes. However, to make good wine or even great wine, nature must be guided by the skilled and artful hand of the winemaker. The author's many years of experience in producing many different wines helps the reader focus on the right processes at the right time to achieve winemaking success. This book stands on the shoulders of the original highly acclaimed text and again it can be said: "Don't make wine without it"!

Following up on his bestselling Winery Technology and Operations, physical chemist and winemaker Yair Margalit comes out with the successive, Concepts in Wine Technology, fully updated and revised to meet the advances of modern winemaking. Among the extended topics are fermentation, skin contact, acid balance, phenolics, bottling, the use of oak and quality control. He begins in the vineyard discussing proper maturation, soil and climate, bunch health, vineyard disease states, and grape varieties. Next he tackles the preharvest with a careful look at vineyard management and preparing the winery for harvest. Dr. Margalit then outlines the entire process of harvesting, from destemming, crushing, and skin contact as it applies to both red and white grapes to pressing, must correction, and temperature control. Fermentation is examined fully and includes a lengthy look at the factors affecting malo-lactic fermentation and its pros and cons. There is a chapter on cellar operations that deals with racking, stabilization, fining, filtration, blending, and maintaining winery hardware, followed by sections on barreling and bottling. The final chapter pulls together the more general aspects of wine technology, covering sulphur-dioxides, different forms of wine spoilage and ways to ward them off, legal regulations and, one of the most important and enigmatic compounds in wine, phenolics.

Attempting to export wine to the U.S. has long been fraught with difficulty, especially for the smaller producers. The U.S. wine industry, complicated by confusing regulations and intense internal brand competition, is also the land of opportunity and home to an adventurous and egalitarian wine consuming population. But without an understanding of how to effectively enter this complex market, the exporter often founders and retreats in frustration. This book provides a guide to approaching and attracting an importer, differentiating terms and regulations which must be understood to prosper, and avenues to achieving and sustaining attainable sales and distribution goals.

"Wine is made in the vineyard" is the mantra of many a winemaker. But what does it mean, really? Esteemed winemaker and biodynamic pioneer Nicholas Joly believes a wine that is well-made in the vineyard must express its unique terroir—the character imbued by a vine's particular plot of well-tended earth. In Biodynamic Wine, Demystified, Joly shares the core philosophy behind biodynamic viticulture and why such practices result in wines of regional distinction. This process treats the vineyard as a self-perpetuating ecological whole influenced not only by terrestrial forces but those of the sun, moon and cosmos. He explains why the use of foreign substances such as pesticides and fertilizers in the vineyard, and aromatic yeasts and enzymes in the cellar, as well as mechanisms such as electric motors and pumps, disrupt this synergy and are ultimately counterproductive to a wine's best, consistent expression.

Any student who has ever logged credits in a viticulture and enology class knows David Bird's book: it is the most widely assigned wine science primer in the English-speaking world. This completely revised and updated edition to Bird's classic textbook deciphers all the new scientific advances from the last several years, and conveys them in his typically clear and plainspoken style that renders even the densest subject matter freshman friendly. The new material includes an expanded section on the production of red, rose, white, sweet, sparkling, and fortified wines; information on histamine, flash detente, maceration, and whole bunch and whole berry fermentation; an expanded chapter on wine faults, including Brettanomyces; a new section on HACCP analysis as applied to a winery; and much more.

Author and entomologist Clifford P. Ohmart brings reason and clarity to the politically loaded and amorphously defined popular world of sustainable viticulture with this unique and comprehensive examination of the subject. View from the Vineyard does much more than explain what "sustainable" means, its practical importance to the wine industry, and the costs of agribusiness as usual. It provides the farmer with a realistic and achievable path to a sustainable vineyard by describing the challenges of practicing sustainable winegrowing, where integrated pest management fits in, how organic and sustainable farming related, a holistic vision for the farm, how to identify and define your farm's resources, methods for developing sustainable goals, creating a plan to achieve your holistic vision, ecosystem management, and understanding the vineyard as habitat. The book concludes with a self-assessment guide in which growers can easily track their progress through these transitional periods.
