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).

Polyphenolic profile and dietary fiber content of skins and seeds from unfermented and fermented grape pomace

The valorization of winemaking byproducts is subordinated to the knowledge of their chemical characteristics. This work concerned the determination of the polyphenolic profile and the dietary fiber content of skins and seeds from unfermented and fermented pomace of different cultivars (Moscato bianco, Cortese, Arneis, Pinot Noir, Barbera, Grignolino, Nebbiolo), sampled from some wineries in the Piedmont area (Italy) during the 2020 harvest.

Enhancing vineyard resilience: evaluating sustainable practices in the Douro demarcated region

In mediterranean agriculture, sustainability and productivity are seriously threatened by climate change and water scarcity. This situation is exacerbated by poor management practices such as excessive use of agrochemicals, overgrazing, and monoculture. The Douro demarcated region (ddr) is an emblematic region, classified world heritage site by UNESCO in 2001. Viticulture is the main agricultural activity in DDR, widely known to produce port wine.

Use of pectinolytic yeast in wine fermentations

The use of pectinolytic enzymes in winemaking is state of the art. These enzymes catalyse the degradation of pectic substances through depolymerization (hydrolases and lyases) and de-esterification. As a result, it supports the extraction of juice and facilitates filtration. It has also been shown in winemaking that the presence of pectinolytic enzymes improves the stability, taste, texture, colour and aroma of products. With regard to enzymes currently applied in winemaking, enzymes derived from filamentous fungi dominate the enzyme industry. Fungal-based pectinolytic enzymes specifically require purification from the culture medium to eliminate unwanted side reactions, which is poorly sustainable. Some non-traditional yeast strains have been reported to exhibit pectinolytic activities. Therefore, the direct use of pectinolytic yeast during wine fermentation process can be an attractive and alternative source for the use of enzymes as input.

High-throughput screening of physical-mechanical berry skin traits facilitates targeted selection of breeding material with resistance to Botrytis bunch rot and grape sunburn

The ongoing climate change implies an increasing mean air temperature, which is signified by weather extremes or sudden changes between drought and local heavy rainfalls. These changing conditions are especially challenging for the established grapevine varieties growing under cool climate conditions due to an increased risk for fungal diseases like downy mildew (DM) and Botrytis bunch rot (BBR) as well as for grape sunburn. To meet that demand, the scope of most grapevine breeding programs is the selection of mildew fungus-resistant and climatic adapted grapevines with balanced, healthy yield and outstanding wine quality.
