Following the enormous decade-long success of his best-selling 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 pre-harvest 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 huge chapter on cellar operations that deals with racking, stabilization, fining, filtration, blending and maintaining winery hardware, followed by sections on barrelling 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 primary text since 1997 for scores of universities and winemakers in a dozen countries, Concepts in Wine Chemistry, by physical chemist and winemaker Yair Margalit, is now totally revised and updated, making it, in editor James Crumb's, Ph.D. words, "the broadest, most meticulous book on the topic in print." Under study here is the basic and advanced chemistry behind the practical concepts of winemaking: must and wine composition, fermentation, phenolic compounds, aroma and flavor, oxidation and wine aging, oak products, sulfur dioxide, cellar processes and wine faults. Dr. Margalit also gives the biochemist's slant on the question: is wine good for you? New to this edition are the latest discoveries that have changed winemaking and brought about new techniques and innovations, including advances in the understanding of volatile esters, red wine phenolic compounds, yeast and factors affecting fermentation, flavour compounds and red-wine colour characteristics, technical properties of "naturally fermented" wines, pesticide use, malolactic fermentation, and the use of wood.
