Effect of culture and familiarity on wine perception: a study with spanish and british wine experts

Abstract

AIM: Wine perception results from the interaction between the wine and its intrinsic and extrinsic characteristics and the experience [1], background and beliefs of the consumer [2,3]. Among all of the factors affecting wine perception, in this study we focused on culture and cognitive processes, working under the hypothesis that higher familiarity with wines would induce higher perceived quality. Furthermore, we hypothesised that culture would influence the verbalisation of wine properties associated with the different experiences of consumers from different cultures.

METHODS: A total of 18 white wines from two countries and four different grape varieties (Vitis vinifera cvs Bacchus and Ortega from the United Kingdom and Vitis vinifera cvs Verdejo and Albariño from Spain) were sensorially assessed by 32 wine experts (16 from La Rioja, Spain, and 16 from East Sussex, England). In each country, all participants were invited to describe the wines according to a labelled free sorting task and to evaluate wine quality using a categorisation task with five pre-established quality categories viz; very low, low, average, high and very high. The order of presentation of tasks was randomized in each country.

RESULTS: Two-way ANOVA with the country of origin of experts (CO) and wines (W) as independent variable showed a significant interaction effect (CO*W) for quality judgements (F = 2.019; P < 0.01), suggesting that quality scores of wines depended on the country-of-origin of experts. It was observed that only four out of the 18 wines evaluated showed significant differences in quality scores. Three of them were Spanish wines that were perceived to be of higher quality by Spanish experts, and the fourth wine was a British wine perceived to be higher in quality by British experts. These results could only partially confirm our initial hypothesis related to the impact of familiarity on increasing the perception of quality.

With regard to the groups formed through the sorting task (non-verbal strategy), both groups of experts used a similar strategy with the wines mainly separated by grape variety. Regarding the differences in the description of the wines overall, they used similar terms. The only difference observed was associated with increased use of the term “floral” by Spanish experts, while the term “flat wine” appeared more constantly in British descriptions.

CONCLUSIONS:

The present work improves our knowledge of the cognitive factors and cultural aspects influencing wine perception. Familiarity with the product can affect perception of quality and the verbalisation of sensory properties among wine experts.

Statewide relationships between water potentials, gas exchange and δ13c of grape musts in California. Implications for use in precision viticulture

The measurement of carbon isotopic discrimination of musts (δ13C) at harvest is an integrated assessment of water status during ripening of grapevine. It is an alternative to traditional measurements of water status in the field, which is crucial for understanding spatial variability of plant physiology at the vineyard scale, proven useful for delineation of management zones in precision viticulture. The aim of this work was to attune the method for the first time to California conditions across a range of areas and cultivars with different hydric behavior, and to evaluate its efficiency in delineating management zones for selective harvest in commercial vineyards.

WINE SWIRLING: A FIRST STEP TOWARDS THE UNLOCKING OF THE WINE’STASTER GESTURE

Right after the pouring of wine in a glass, a myriad of volatile organic compounds, including ethanol, overwhelm the glass headspace, thus causing the so-called wine’s bouquet [1]. Otherwise, it is worth noting that during wine tasting, most people automatically swirl their glass to enhance the release of aromas in the glass headspace [1]. About a decade ago, Swiss researchers revealed the complex fluid mechanics underlying wine swirling [2]. However, despite mechanically repeated throughout wine tasting, the consequences of glass swirling on the chemical space found in the headspace of wine glasses are still barely known.

Les sols du cru de Bonnezeaux, Thouarcé, Anjou, France

Le cru de Bonnezeaux est une des appellations prestigieuses des vins liquoreux et moelleux des Coteaux du Layon et sa réputation est ancienne. L’INAO a effectué sa délimitation en 1953. Le vignoble est situé au nord de la ville de Thouarcé et au sud du village de Bonnezeaux, le long du versant rive droite du Layon, exposé au sud-ouest. La superficie du vignoble est de 156 ha.

NEW METHOD FOR THE QUANTIFICATION OF CONDENSED TANNINS AND OTHER WINE PHENOLIC COMPOUNDS USING THE AUTOMATED BIOSYSTEMS SPICA ANALIZER

Wine phenolic compounds are important secondary metabolites in enology due to their antioxidant and nutraceutical properties, and their role in the development of color, taste, and protection of wine from oxidation and spoilage. Tannins are valuable phenolic compounds that contribute significantly to these wine properties, especially in mouthfeel characteristics; however, tannin determination remains a significant challenge, with manual and time-consuming methods or complex methodologies. The purpose of this study is to propose a novel method for quantifying condensed tannins in finished wine products.

The surprising role of VvLYK6 in grapevine immune responses triggered by chitin oligomers

For sustainable viticulture, the substitution of chemical inputs with biocontrol products has become one of the most considered strategies. This strategy is based on elicitor-triggered immunity that requires a deep understanding of the molecular mechanisms involved in plant defense activation. Plant immune responses are triggered through the perception of conserved microbe-associated molecular patterns (MAMPs) which are recognized by pattern recognition receptors (PRRs) at the plasma membrane.
