Development and management of winemaking sustainability: an explorative survey in Sicily
2016
Sustainability is reshaping the global wine industry. This paper provides a fact-finding contribution to the knowledge on how the Sicilian winegrowing sector is facing the challenge of the new scenario of sustainable productions. To reach this goal we carried out an explorative analysis of those Sicilian wineries involved in 2 important sustainability programs in the Italian wine sector, Magis and SOStain, aimed at improve the implementation of sustainable viticulture and wine production. The results of our research concerning 5 wineries in Sicily reveal that adopting sustainable productive methods has lead in general to good technical and financial results by improving their business effic…
Sensory drivers of intrinsic quality of red wines
2013
Abstract The present study aims at evaluating the effect of culture and level of expertise on the perception of wine intrinsic quality. Therefore, regular consumers (108) and experts (119) from La Rioja (RJ-Spain) and Cotes du Rhone (CdR-France) evaluated the intrinsic quality of 12 red wines from both regions. Participants had to categorise the wines according to four levels of quality going from very low to very high quality. Results show no significant correlation between the quality scores given by experts and regular consumers whereas judgments given by French and Spanish experts are significantly correlated as are consumers' quality judgments. This demonstrates that perceived intrinsi…
Conceptual vs. perceptual wine spaces: Does expertise matter?
2008
Abstract This study explores the differences in wine categorization between wine experts and novice wine consumers using 10 Melon de Bourgogne (MB) and 10 Chardonnay (CH) wines. Participants performed a free sorting task based on odor similarity followed by a CH and a MB typicality rating task and a liking rating. All tasks were performed orthonasally. We observed a clear agreement between experts concerning typicality scores. Moreover, despite a slight overlap we found a clear differentiation between CH and MB for experts’ typicality scores. For novices, no such agreement on typicality scores was observed and we found a complete overlap between both types of wines. These results suggest th…
Contribution of the Temporal Dominance of Sensations (TDS) method to the sensory description of subtle differences in partially dealcoholized red win…
2009
Abstract In this study, effect of partial alcohol reduction on the sensory modification of red wines was investigated. A Merlot and a Syrah wine were partially dealcoholized using reverse osmosis technique to span a range of three different alcohol contents (14–10%) by grape variety. Preliminary triangle tests indicated the existence of very slight differences between the dealcoholized wines of the study. Therefore, adapted descriptive methodologies had to be used. In a first step, wines were described with a comparative sensory profile by 16 trained panellists on 15 sensory attributes. Then, the same panellists profiled the wines with the TDS technique, which consists in identifying and ra…
Exemplarity measurement and estimation of the level of interjudge agreement for two categories of French red wines
2015
Abstract Exemplarity measurements of wines by at least 20 judges are used to estimate the degree of interjudge (dis)agreement and to tell wines apart into two contrasting extremes. Two sets of French red wines – Pinot noir from Burgundy and Cabernet franc from the Loire Valley – are studied separately but by the same approach. Short-listing criteria are used to collate 40 starting-price and middle-range wines for each set differing a priori in olfactory terms. Wine professionals assess their local wines first orthonasally and then, independently, by global evaluation. A pool of descriptive and inferential statistics indicates there is generally neither complete divergence nor real agreement…
Perceived minerality in Sauvignon wines: influence of culture and perception mode
2015
Abstract Description of wine in terms of perceived mineral character has become common practice in recent decades. The major aim of our study was to investigate cultural differences in perception of minerality in wines from France and New Zealand, these countries having very different wine-production histories. A second aim was to investigate influence of perception mode on perceived mineral character in wine to gain increased understanding of the metaphorical descriptor “mineral” as applied to wine chemosensory attributes. Thirty-two French and 31 New Zealand wine professionals evaluated 16 wines (8 French; 8 New Zealand) under three conditions: orthonasal olfaction; global (orthonasal and…
Extrinsic attributes responsible for red wine quality perception: A cross-cultural study between France and Spain
2014
Understanding quality perception requires focusing both on product proprieties and consumers' representations. The goal of this study was to access the representations of perceived extrinsic wine quality of consumers from two different wine regions in two European countries with an important wine tradition: La Rioja-RJ-(Spain) and Cotes du Rhone-CdR-(France). Twenty commercial red wines (ten from RJ and ten from CdR) were evaluated in terms of quality by means of a categorization task. Ninety-five French and 93 Spanish consumers had to categorize the 20 wines according to four levels of quality going from very low to very high quality. Three clusters of French and two of Spanish consumers h…
Logos indicating environmental sustainability in wine production: An exploratory study on how do Burgundy wine consumers perceive them
2014
Corrigendum to “Logos indicating environmental sustainability in wine production: An exploratory study on how do Burgundy wine consumers perceive them”Food Research International, Volume 66, December 2014, Page 515; Logos on environmental sustainability could consist of an effective strategy to provide consumers with accurate, understandable and trustworthy information to encourage them to buy environmentally sustainable wines. However, the large number of different logos indicating environmental sustainability available in the market raises the question of whether their associated messages are successfully conveyed to consumers. In this context, the aim of the present exploratory study was…
Communicating Personal Goals: Consequences for Person Perception in the Work and Family Domains
2006
Based on a set of three experimental studies (total N = 608), we examined how people appraise another person’s well-being and motivation in the work and family domains on the basis of knowledge of this other person’s goal system. Participants were introduced to the life situation of either a woman or a man belonging to a successful dual-career couple. This target person reported pursuing only work-related personal goals (work priority), only family-related personal goals (family priority) or both work- and family-related goals (balanced goal system). Participants were asked to appraise the target person’s life satisfaction as well as a number of work- and family-related attributes. Overall…
Collaborative Writing with Wikis: Pedagogical and Technological Implications for Successful Implementation in Teacher Education
2012
Wikis have been promoted as tools that foster collaborative learning and writing. They enable multiple users to edit a document collaboratively and support online written communication between participants. While most wiki research is based on students’ subjective perceptions of the wiki learning environment, a number of studies have drawn on the data log that is automatically generated by wikis. The data log enables the analysis of students’ activities performed on the wiki in terms of work distribution, level of contribution, types of activities, timing of contribution, and work intervals. This information is more reliable to analyze collaborative writing activities than subjective percep…
