Wine Chemistry and Biochemistry - PDF Free DownloadThe aim of this book is to describe chemical and biochemical aspects of winemaking that are currently being researched. The authors have selected the very best experts for each of the areas. The first part of the book summarizes the most important aspects of winemaking technology and microbiology. The second most extensive part deals with the different groups of compounds, how these are modified during the various steps of the production process, and how they affect the wine quality, sensorial aspects, and physiological activity, etc. The third section describes undesirable alterations of wines, including those affecting quality and food safety. Finally, the treatment of data will be considered, an aspect which has not yet been tackled in any other book on enology. In this chapter, the authors not only explain the tools available for analytical data processing, but also indicate the most appropriate treatment to apply, depending on the information required, illustrating with examples throughout the chapter from enological literature.

Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4. Gum arabic has been used in the past as fining agent. A wine fault or defect is an unpleasant characteristic of a wine often resulting from poor winemaking practices or storage conditions , and leading to wine spoilage. Many of the compounds that cause wine faults are already naturally present in wine but at insufficient concentrations to adversely affect it. However, when the concentration of these compounds greatly exceeds the sensory threshold , they replace or obscure the flavors and aromas that the wine should be expressing or that the winemaker wants the wine to express. Ultimately the quality of the wine is reduced, making it less appealing and sometimes undrinkable.
