Book excerpt: The aim of this research was to investigate the use of oak alternatives by the wine industry, and specifically, to explore their influence on the composition, sensory properties, and consumer acceptability of wine. A detailed online consumer questionnaire was administered nationally to wine consumers to explore their knowledge of and attitudes towards the use of oak during winemaking. Within the sample population surveyed (n=1015), four distinct consumer segments were identified, each with significantly different attitudes towards the use of oak alternatives for wine maturation. A segment of more knowledgeable consumers, who appreciate and value traditional barrel maturation, held slightly negative views of wines produced with oak alternatives. However, a second cluster comprising less knowledgeable consumers were accepting of the use of oak alternatives, provided wine quality was not affected. The results from this study have advanced our understanding of consumer attitudes towards innovative oak technologies and provide justification for the use of oak alternatives by winemakers, who can now tailor their wines to better meet the expectations of specific segments of their target market. A maturation trial was subsequently established to examine the effect of different storage vessels on wine composition and sensory properties. The specific objective of the trial was to compare vessels comprising three different panel types, i.e. stainless steel, plastic and oak wood panels, and the potential for each to produce wines of comparable composition and quality to those aged traditionally in barrels. The outcomes of the 12 month trial demonstrated that the different storage vessels each imparted oak characters to wine and therefore afford winemakers an alternative method for the oak maturation of wine. In a second maturation trial, traditional and alternative oak maturation regimes were employed to age Cabernet Sauvignon wines and the effect of each treatment on the composition, sensory properties and consumer acceptance of wine investigated. Acceptability scores from 116 consumers revealed no significant differences in consumers' overall liking of each wine, but segmentation based on individual liking scores identified three distinct clusters comprising consumers with significantly different wine preferences. Multivariate data analysis revealed the sensory attributes driving wine preference for each consumer segment. These results further justify wine producers' use of alternative oak maturation regimes to reduce production costs and achieve wine styles that appeal to different segments of the consumer market. To gain a holistic view of consumer preferences for oak attributes in wine, a third consumer study was undertaken to investigate the effect of key oak aromas on consumer emotions. Consumers (n=116) were asked to rate their liking of eight oak-derived aromas and to then consider how different oak aromas make them feel. Consumers scored each aroma favourably, but spice and chocolate were liked most, and smoky and coconut aromas were liked least. Segmentation of consumer liking scores revealed three segments which differed in their liking of and emotional response to different oak aromas, but differences were subtle. This study showed oak aromas generally elicited positive emotions, but broader classes of aromas, e.g. oak derived aromas versus fruit aromas (e.g. citrus, berry or tropical fruit), may elicit stronger emotional responses than individual oak aromas. An additional study reporting the convenient, low-cost preparation of isotopically labelled volatile wine phenols, using microwave-assisted deuterium exchange, was also conducted. The development of a method that incorporates deuterium atoms on the aromatic ring offers significant benefits for quantitative GC-MS analysis by stable isotope dilution analysis, i.e. improved accuracy and reproducibility, and this study complemented the aforementioned consumer research.

Available in PDF, EPUB and Kindle. Book excerpt: The impact of storing red wine in stainless steel containers with micro-oxygenation in conjunction with a variety of oak alternatives on phenolic composition and wine aging was investigated and compared with traditional barrel aging. A blended red wine was aged in new French and American oak barrels, as well as in sealed stainless steel vessels, which were connected to a micro-oxygenation system and either oak chips, oak staves or oak tannin extracts. Oxygen was administered at a rate of 1 mg per liter per month in order to emulate the ingress of oxygen occurring in the oak barrels. After 6 months of treatment, all wines were bottled. All wines were analyzed at 3 and 6 months of treatment and after 5 months of bottle aging by UV-vis, phloroglucinolysis and LC/MS. Differences in color formation, likely due in part to the catalytic effect of oxygen and ellagic tannins on indirect polymerization reactions, were observed between different treatments. After five months of bottle aging, all wines were assessed sensorially via descriptive analysis, with an emphasis placed on distinguishing differences in mouthfeel characteristics. Results indicate that wood treatment dominated differences between treatments with positive aroma attributes of sweet, woody, spicy and vanilla. Mouthfeel attributes did not distinguish significantly.

Download or read book Post Fermentation and Distillation Technology written by Matteo Bordiga and published by CRC Press. This book was released on 2017-12-15 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: While most wine and spirits books focus on vineyard and crop management or fermentation and distillation processes, few address critical post process aspects of stabilization, aging, and spoilage. This book serves as a comprehensive source of information on post-fermentation and -distillation technology applied to wine, beer, vinegar and distillates in a broad spectrum. Post-Fermentation and -Distillation Technology: Stabilization, Aging, and Spoilage thoroughly describes all of the operations related to these products after the fermentation or distillation steps, focusing on the complex issues related to their stabilization, aging, and spoilage. The final product must be stable against microbial activity as well as undesirable chemical and physical chemical reactions that occur in the bottle. For example, clarity, stability, compositional adjustment, style development and packaging represent the five goals of "finishing" a wine. Concerning the visual defects associated with spoilage, it is crucial that wine at the point of consumption not be cloudy or contain any haze or precipitate, especially white wines. Similarly, it is also important to prevent unwanted microbial growth from occurring in the wine after the primary fermentation is complete, affecting the flavor and aroma profile in unpredicted ways. The book addresses all of these issues and more. Moreover, the discussion also involves beer, vinegar and distillates, giving this book a novel and interesting approach. The book combines referenced research with practical applications and case studies of novel technologies such as square barrels, synthetic closures, and Tetra Pak®.

Download or read book Wood Beer written by Dick Cantwell and published by Brewers Publications. This book was released on 2016-05-25 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Join authors Dick Cantwell and Peter Bouckaert as they tell the story of the marriage between wood and beer from Roman times through medieval Europe to modern craft brewing. Cooperage is a long and venerable craft and here the authors give a description combining the evocative and technical. The smells, the heat, choosing the wood, drying, fashioning staves, steaming, firing, and assembling into a perfect container—at least perfect until the bunghole is drilled to accommodate the precious contents. Barrels and foeders have gone from an oddity of traditional breweries to a commonplace feature at the heart of the craft brewing industry. It is estimated that 85% of US breweries now use wood as part of their process. Maintaining wooden vessels requires care and meticulous organization of cellar space. The authors discuss the vagaries of temperature, humidity, seasonal changes, mold, and evaporation, and how breweries new and old deal with these challenges. The basics of selecting, inspecting, cleaning, and maintaining barrels are detailed. Finally, of course, the wood must be united with the beer. The complexity and variations that govern how wood imparts flavors to beer can be overwhelming. The authors guide the reader through wood's characteristic flavor compounds and the nuances of toasting and charring. Oak is the focus, American, French, and Eastern European, but other woods get their due. As well as intrinsic flavors, the microflora that take up residence in a barrel or foeder are the living, beating heart of a barrel-aged beer, able to create sour and unique beers of fascinating complexity. The authors pepper the text with stories and experiences from some of the giants of the craft brewing scene, discussing how they monitor their barrel programs and taste and blend their beers to create something truly special. All this will inspire professional and amateur brewers alike. At the end of the book the authors give some helpful advice on wood aging for homebrewers, including the uses for chips, cubes, spirals, staves, powders ... and the odd chair leg. Get ready to embrace the mystical complexity of flavors and aromas derived from wood.
