Wine Tasting: A Professional Handbook
Format: PDF / Kindle (mobi) / ePub
One of the most respected professionals in the wine industry-Ron Jackson, author of Wine Science (now in its second edition)- covers all practical and theoretical aspects of wine tasting in his new book. It details the basic techniques used by professionals to sense all visual, gustatory, and olfactory wine properties (sight, taste, and smell). It also describes the physiologic, psychologic, and physicochemical origins of sensory perception and discusses wine types to illustrate the characteristic features that distinguish the majority of wines. A large portion of the book is dedicated to the practical concerns of preparing and performing wine assessments. Readers are instructed in how to differentiate between the various types of wine tastings (each requiring its own design, tasting sheets, training, skill measurement, and analysis). Included is a general overview of the types and sources of wine quality and how wine is most appropriately paired with food. Special features include a flow chart of wine tasting steps, details of errors to avoid, procedures for training and testing sensory skills, sample tasting sheets, original data from 14+ years of training tasters, and numerous tables, charts, and figures.

Although environmental conditions signiﬁcantly affect the hedonic response to odors (and wines), genetic differences in odor responsiveness are presumably involved. For example, androsterone elicits a variety of responses. People generally fall into one of three classes—those detecting androsterone at low

analysis has been used primarily in studying or validating features thought to distinguish wines made from particular varieties (Guinard and Cliff, 1987), produced in speciﬁc regions (Williams et al., 1982), or made in distinctive styles. Sensory analysis has also been used in investigating the climatic features of a region that make it appropriate for producing particular wine styles (Falcetti and Scienza, 1992). It can also study the effects of changing viticultural or enological procedures. In
