This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging of wines in oak barrels is an integral part of many winemaking styles. Oak derived volatiles are important contributors to the overall aroma of such wines. The extent of toasting by commercial cooperages impacts the volatile composition of barrels which in turn affects the volatile composition of the wine. The goal of this study was to investigate the sources of variation in the toasting process to identify processing steps which are critical to achieve consistent results from the barrel making process.The first section of this study focused on the bending and toasting processes at a commercial cooperage, in which the unfinished barrels are heated over a wood fire until the staves can be bent readily. After bending, the barrels are further heated over additional wood fires to achieve the desired toasting level. In this study, wireless thermocouples were imbedded in staves to assess the variability in the temperature experienced by the staves during the bending and toasting process. Samples of the wood around the thermocouples were analyzed by GC-MS/MS to assess the impact of heating on the volatile composition of the wood. The temperature profiling demonstrated that the wood received differing amounts of heat depending on proximity to the flames as well as the distance from the firepot itself. Varying chemical profiles resulted from the differential heating; depending in part on the origin of the volatiles, different patterns of formation and/or degradation were observed. This study demonstrated that the range in maximum temperature achieved during a production run of barrels can be as large as 30°C. The variability in volatile composition of barrels during a production run was related to the variability in temperature profiles. This study also documented the variability associated with the individual coopers managing the toasting process. As a visual demonstration of the effects of variability in the toasting process, a series of "maps" of the volatile composition of every stave in a single barrel was produced.The second section of this study evaluated the relative impact of forest of origin and grain tightness of wood on the resulting chemical and sensory properties of the wine aged in the study barrels. Oak stave wood from the Allier, Nevers and Vosges forests was selected for grain tightness. Four barrels of each combination of forest and grain were made using a consistent barrel making protocol. The barrels were filled with Chardonnay juice from a single vineyard; after barrel fermentation and 8 months of aging, the wines were sampled, filtered and bottled. The wines were analyzed using GC-MS/MS for oak related volatile compounds; the wines were also analyzed for their polyphenol levels using a spectrophotometric assay. The wines were evaluated using a sensory technique known as Projective Mapping, first by a panel of experts and then by a panel of students. It was possible using the chemical analyses to differentiate amongst some, but not all, combinations of forest and/or grain tightness. Neither the expert panel nor the student panel was able to find sensory differences amongst the combinations of forest and grain tightness, although a subset of the most experienced expert tasters performed somewhat better than the panel as a whole. The differences that may have been present due to forest of origin or grain tightness were relatively small compared to the variability in volatile composition resulting from the toasting process.

Available in PDF, EPUB and Kindle. Book excerpt: "Matthews brings a scientist's skepticism and scrutiny to widely held ideas and beliefs about viticulture--often promulgated by people who have not tried to grow grapes for a living--and subjects them to critical examination: Is terroir primarily a marketing ploy that obscures our understanding of which environments really produce the best wine? Can grapevines that yield a high berry crop generate wines of high quality? What does it mean to have vines that are balanced or grapes that are fully mature? Do biodynamic practices violate biological principles? These and other questions will be addressed in a book that could alternatively be titled (in homage to a PUP bestseller) On Wine Bullshit"--Provided by publisher.

Download or read book The Terroir of Whiskey written by Rob Arnold and published by Columbia University Press. This book was released on 2020-12-22 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Look at the back label of a bottle of wine and you may well see a reference to its terroir, the total local environment of the vineyard that grew the grapes, from its soil to the climate. Winemakers universally accept that where a grape is grown influences its chemistry, which in turn changes the flavor of the wine. A detailed system has codified the idea that place matters to wine. So why don’t we feel the same way about whiskey? In this book, the master distiller Rob Arnold reveals how innovative whiskey producers are recapturing a sense of place to create distinctive, nuanced flavors. He takes readers on a world tour of whiskey and the science of flavor, stopping along the way at distilleries in Kentucky, New York, Texas, Ireland, and Scotland. Arnold puts the spotlight on a new generation of distillers, plant breeders, and local farmers who are bringing back long-forgotten grain flavors and creating new ones in pursuit of terroir. In the twentieth century, we inadvertently bred distinctive tastes out of grains in favor of high yields—but today’s artisans have teamed up to remove themselves from the commodity grain system, resurrect heirloom cereals, bring new varieties to life, and recapture the flavors of specific local ingredients. The Terroir of Whiskey makes the scientific and cultural cases that terroir is as important in whiskey as it is in wine.
