Winery Technologies And Operations

Outlines various levels of the vinification process, from the vineyard to the cellar.

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.

The original handbook for professional winemakers written by a professor of chemistry who is also a practicing winemaker. Everything you need to know from grape harvest to the bottling laboratory with practical charts and tables.Includes pre-harvest operations, sulfur-dioxide, skin contact, must corrections, yeast, cellar operations, fining, oak and aging, quality control, analysis of must and wine and specifics for setting up your wine lab. Ideal for students and cellar rats.

Red Wine Technology is a solutions-based approach on the challenges associated with red wine production. It focuses on the technology and biotechnology of red wines, and is ideal for anyone who needs a quick reference on novel ways to increase and improve overall red wine production and innovation. The book provides emerging trends in modern enology, including molecular tools for wine quality and analysis. It includes sections on new ways of maceration extraction, alternative microorganisms for alcoholic fermentation, and malolactic fermentation. Recent studies and technological advancements to improve grape maturity and production are also presented, along with tactics to control PH level. This book is an essential resource for wine producers, researchers, practitioners, technologists and students. Winner of the OIV Award 2019 (Category: Enology), International Organization of Vine and Wine Provides innovative technologies to improve maceration and color/tannin extraction, which influences color stability due to the formation of pyranoanthocyanins and polymeric pigments Contains deep evaluations of barrel ageing as well as new alternatives such as microoxigenation, chips, and biological ageing on lees Explores emerging biotechnologies for red wine fermentation including the use of non-Saccharomyces yeasts and yeast-bacteria coinoculations, which have effects in wine aroma and sensory quality, and also control spoilage microorganisms

This book has been written for an eclectic audience of winery developers (owners), winemakers with utility responsibilities (real or implied), winery design professionals (architects and engineers), and university-level enol ogy professors, all of whom at sometime in their careers must address the subject of winery site utilities as a distinct and important element of their jobs. Wine and other fermented beverages in one form or another are pro duced commercially in almost all temperate zones of the world. Utility requirements for wineries, which use grapes as the fermentable sugar source, are the focus of this reference book, although similarities in fun damental production processes for other subdivisions of the fermented beverage industry may find useful reference information in the chapters which follow. Wine production methods may differ somewhat from country to coun try, but the sizing, need for reliability, ease of operation, and cost-effec tiveness of water, wastewater, electrical, fire protection, and other support systems remain nearly universally constant. Of necessity, the author's past planning and design experience with nearly 60 winery utility systems, will xi xii Preface emphasize contemporary design fundamentals related to the U.S. wine industry. However, where possible, opportunities will be taken to relate American practice to, for example, European, Australian, and South Amer ican wine industries where discrete differences in utility systems have been observed by the author or discovered in the literature research that was part of the production effort for this volume.

Unit Operations in Winery, Brewery, and Distillery Design focuses on process design for wineries, breweries, and distilleries; and fills the need for a title that focuses on the challenges inherent to specifying and building alcoholic beverage production facilities. This text walks through the process flow of grapes to wine, grain to beer, and wine and beer to distilled spirits, with an emphasis on the underlying engineering principles, the equipment involved in these processes, and the selection and design of said equipment. Outlines the process flow of alcoholic beverage production Reviews process engineering fundamentals (mass & energy balances, fluid flow, materials receiving & preparation, heat exchange, fermentation, downstream processing, distillation, ageing, packaging, utilities, control systems, and plant layout) and their application to beverage plants Describes the idea of sanitary design and its application to plant operation and design Covers critical equipment parameters for purchasing, operating, and maintaining systems Shows how winery/brewery/distillery can influence product "style" and how "style" can dictate design Features examples of calculations derived from wineries designed by the authors, end of chapter problems, and integrative in-text problems that describe real-world issues and extend understanding Written for both engineers in the alcohol industry and non-engineers looking to understand facility design, this textbook is aimed at students, winemakers, brewers, distillers, and process engineers.

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"!
