Consumers’ emotional responses elicited by wines according to organoleptic quality

Abstract

Wine is often described with emotional terms, such as surprising, disappointing or pleasant. However, very little has been done to really characterize this link between emotions and wine. Can it really bring emotions to wine tasters? Many studies have looked at the extrinsic factors that can improve the emotional experience of tasters when discovering a wine (Danner et al. 2016, 2017), but few have been carried out on the emotional impact of the organoleptic characteristics of wines. One study, however, has shown that where novice consumers fail to distinguish two different styles of red wine using conventional sensory descriptors, they manage to do it with emotional attributes (Coste et al. 2018). This new approach highlights a role for emotions in tasting, and it seems interesting to try to better understand and characterize this role. The present study explored the link between organoleptic quality defined by tasting experts and emotions felt by consumers (connoisseurs). Different red Bordeaux wines, with different sensory properties and different levels of quality (defined by wine experts) have been tasted by 65 connoisseurs. Emotions were measured using both direct and indirect methods. The evaluation of the conscious part of emotions was conducted with cognitive measurements, using self-declarative questionnaires. The unconscious part of emotions was evaluated with two types of measurements. One measures the behavioral component of emotions with facial expressions, and the other measures the response of the autonomic nervous system with physiological data known to be correlated to emotional response, such as heart rate, respiratory rate and skin conductance level. Finally, the aim was to evaluate whether it is possible to differentiate wines through emotions and which type of measure (conscious or unconscious) is the most relevant. The results were compared with classical approach in sensory analysis with consumers (measure of hedonic perception).

Preliminary results of water status and metabolite content of three new crossbreed winegrape genotypes

This study presents the preliminary results obtained in 2022, of the evaluation of three new crossbreed winegrape genotypes and their parental varieties, grown under controlled irrigation (60% ETc) and rainfed conditions in a wine-growing area with scarcity of water and high temperatures (Murcia, southeast Spain). The genotypes MC16 and MC80 were obtained from crosses between the varieties ‘Monastrell’ and ‘Cabernet Sauvignon’, and MS104 from crosses between ‘Monastrell’ and ‘Syrah’ [1]. The objective of this study was to analyse the physiological response and vegetative development of the 6 genotypes under the two irrigation conditions, and to study their effect on the content of soluble sugars and chlorophyll in the leaf.

Optimized protocol for high-quality RNA extraction from grape tissues using sorbitol pre-wash

Obtaining high-quality RNA from grape tissues, including berry pulp, berry skins, stems, rachis, or roots, is challenging due to their composition, which includes polysaccharides, phenolic compounds, sugars, and organic acids that can negatively affect RNA extraction. For instance, polyphenols and other secondary metabolites can bind to RNA, making it difficult to extract a pure sample. Additionally, RNA can co-precipitate with polysaccharides, leading to lower extraction yield. Also, sugars and organic acids can interfere with the pH and ionic properties of the extraction buffer. To address these challenges, we optimized a protocol for RNA isolation from grape tissues.

The revision of the delimitation of the AOC “Champagne”

The Champagne vine-growing region has played a pioneering role in the delimitation of appellations of origin (AOC). The implementation of the Act of July, 22nd 1927 has led to drawing up lists of vine plots based on the criterion of vine cultivation antecedence.

Measurement of grape vine growth for model evaluation

Within a research project for simulating the nitrogen turnover in vineyard soils and the nitrogen uptake by the grape vine, a previously developed plant growth model (Nendel and Kersebaum 2004) had to be evaluated. A dataset was obtained from a monitoring experiment at three vineyard sites with different soil types, conducted in the years 2003 and 2004.

Validation of a method for the determination of volatile compounds in in spirituous beverages using contained ethanol as a reference substance

The results of experimental studies of the method based on the usage of ethyl alcohol as an internal standard for the direct determination of volatile compounds in wines and others alcohol contained products are presented. The method was validated in terms of precision, accuracy, limits of detection and quantification (lod and loq), linearity, and robustness.
