Wearable sensors to measure the influence of sonic seasoning on wine consumers in a live context: a preliminary proof-of-concept study.

Any action capable of creating expectations about product quality would be able to modulate experienced pleasantness. In this context, during the 2022 edition of the Internet Festival (Pisa, Italy) a 'social experiment' was promoted to set up an affordable and reliable methodology based on wearable sensors to measure the emotions aroused in a live context on consumers by different kinds of wines. Therefore, five wines (two faulty ones and three high-quality samples) were proposed to 50 non-selected consumers in an arousing context with live jazz music as background. Both explicit (questionnaires) and two different approaches for implicit methods (electrocardiogram (ECG) recorded by wearable sensors vs. smartphones), the latter performed on a subgroup of 16, to measure the emotions aroused by wines and music were utilized synergistically. According to our findings: (i) wine undoubtedly generates a significant emotional response on consumers; (ii) this answer is multifaceted and attributable to the quality level of the wine tasted. In fact, all things being equal, while drinking wine even untrained consumers can perfectly recognize good wines compared to products of lower quality; (iii) high-quality wines are able to induce a spectrum of positive emotions, as observed by the analysis of ECG signals, especially when they are coupled with background music. The framework has certainly played to the advantage of good-quality wines, fostering their positive emotional characteristics on the palate even of some less experienced consumers, thanks to a dragging effect towards a positive mood generated by the surrounding conditions (good music in a beautiful location). © 2024 Society of Chemical Industry.

Triptan treatment is associated with a higher number of red wine-induced migraine episodes: An exploratory questionnaire-based survey.

Diet, including foods and beverages, affects migraine. Conversely, the influence of migraine therapies on dietary habits is largely unknown. This study aimed at investigating the effects of triptan intake on foods and drinks consumed by adults with migraine with and/or without aura. An exploratory questionnaire-based survey took place online between November 2022 and June 2023. Participants were recruited through advertisements shared on social media accounts (e.g., Facebook and Instagram) and seasonal newsletters of three Danish patient associations. In addition, posters and flyers in headache and pain centers at Danish hospitals and private neurological, pain, and physiotherapeutic clinics were utilized. A total of 314 adults with migraine with and/or without aura completed the survey. Among the respondents, 236 individuals (75.2%) regularly used triptans to treat their migraines. Compared with non-triptan users, individuals using triptans were characterized by significantly more foods and/or drinks triggering migraine (74.2% vs. 56.4%, p = 0.005). Alcoholic beverages and most specifically red wine were overreported as migraine triggers by triptan users (48.3% vs. 21.8%, p < 0.001). In the week preceding the survey, red wine was significantly less consumed by triptan users than non-triptan users (92.4% vs. 76.9%, p < 0.001). Patients who regularly consume triptans report red wine most frequently as a migraine trigger. Triptan users are characterized by a lower consumption of red wine than non-triptan users, suggesting that a regular triptan intake may promote an increased sensitivity to red wine-induced migraine.

Young Consumers’ Preferences for Natural Wine: An Italian Exploratory Study

Although much has been written about sustainable wine consumption, the topic of young consumers’ (age 18–39 years) preferences for natural wine in Italy has been poorly explored. Through an online survey of 640 Italian respondents, we investigate the characteristics that affect consumption of natural wine in Italy. First, a factor analysis was applied to reduce data to a smaller set of summary variables. A probit regression model was then used to explore the effects and evaluate the relative importance of identified factors on participants’ willingness to consume natural wine. The results reveal that being female, in the older age cohort (25–39 years), and being consumer of certified wine and/or biodynamic wine significantly increase the probability of drinking natural wine. The findings also showed that health benefits, natural product interest, previous experience with natural wine, and positive perception of natural wine also drive young consumers of natural wine.

Segmenting Chinese wine consumers on the basis of wine knowledge and consumption behavior

Purpose This study aims to provide insights into wine consumers in Hong Kong and Mainland China, and the diversity of their behavior, by investigating their motivations, consumption and purchasing behavior and segmenting the sample based on wine knowledge and frequency of consumption to identify three distinct clusters that are then profiled. Design/methodology/approach Data was collected through an online survey of wine consumers of ethnic Chinese origin residing in Mainland China and Hong Kong, using two methods of recruitment (a convenience sample from wine-related databases, a panel survey undertaken by an international market research firm). The final sample comprised 477 respondents, about equally divided among Mainland Chinese and Hong Kong wine consumers. Analysis of the data using the Statistical Package for Social Sciences for Windows (SPSS) 29 included a series of descriptive analyses, followed by a two-step cluster analysis using an Euclidean distance method. Findings Wine knowledge and frequency of wine consumption were relatively higher within the sample as a whole than previous studies, but three distinct consumer segments are evident. There is evidence of a democratization of wine consumption, and a greater focus on wine consumption for enjoyment in relaxed and informal settings. rather than consumption driven by health and status, occurring primarily in commercial or business settings. The dominance of red wine in this market is also declining, and intrinsic cues – specifically, prior experience of the wine – are becoming important in wine purchase decisions. Originality/value This study uses a broad sample of wine consumers to identify trends in wine consumption patterns and motivations, and purchase decision-making behavior, of Mainland Chinese and Hong Kong wine consumers. The identification of three clusters of wine consumers offers both points of comparison with previous segmentation research globally and within China, whilst also identifying scope for further research.

Structuring food and wine pairing experiences in an emerging economy – Implications for food and wine pursuits, recreation, and tourism

ABSTRACT By embracing the underpinnings of the structured experience and the experience economy literature, this study explores wine and food consumers in an emerging economy, where change and evolution are distinctive features. Despite a growing literature emphasising the value of food and wine pairings, this leisure activity continues to receive scant academic attention, including in emerging economies where still wine consumption is not an established phenomenon. A questionnaire administered online and targeted to wine and food consumers in various cities in Vietnam elicited 442 valid responses. An exploratory factor analysis revealed the importance of the ‘encompassing’, ‘engaging’, ‘intrinsically rewarding’, and ‘status-oriented’ dimensions. Strong relationships emerged between these dimensions, the structured experience and the experience economy literature. In addition, numerous inter-group differences were confirmed, including the finding that higher levels of income do not determine how consumers perceive their wine and food experiences. The dimensions and associated relationships helped develop a framework that guides the conceptual and practitioner understanding of structured consumer experiences. For instance, the engaging dimension highlights customers’ desire to gain knowledge associated with their experiences, while the intrinsically rewarding dimension points to aspects, including new products, that can address customers’ needs.

PROP taste status has limited impact on wine flavour perception and acceptability by consumers

Individual differences in the perception of oral and retro-olfactive stimuli can affect wine consumer’s preference. The aim of this work was to understand how individual variation in PROP taste status (PTS) (response to 6-n-propylthiouracil) affects the perceived intensity of oral (acid, sweet, bitter, astringency) and retro-olfactive sensory stimuli (fruity and woody aromas) and liking. The correlation between PROP responsiveness and the intensity of basic tastes using impregnated strips and with saliva composition, was also assessed. A cohort of wine consumers (n = 279) segmented by age-gender (being 45 y.o. the cut-off point for young/adult) and characterized by their PTS, tested six white and six red wines (WW, RW) modified with chemical compounds to elicit a predominant sensory stimulus. Results from comparing supertasters (STs) and no tasters (NTs) consumers showed a positive correlation (p < 0.05) between the perception of most basic tastes (acid, bitter, salty) and PROP responsiveness. However, salivary flow rate and total proteins did not show significant differences depending on PTS. The relationship of PTS with perceived intensity and acceptability was also rather low when evaluating the wines. Only the intensity scores of some sensory stimuli (woody aroma, astringency, sweet taste) showed a trend (p < 0.10). Young STs scored with higher intensity the woody aroma (females) and the sweet taste (males) of RW. NTs young-males and adult-females perceived with higher intensity the astringency and woody aroma of WW respectively. The effect of PTS on wine liking was also limited to some specific sensory attributes (sweet, astringent, fruity) mainly in white wines.

Country of origin effect in the preferences of wine consumers in new markets

El efecto país origen ha sido protagonista de numerosos estudios durante varios años, donde se ha afirmado que es un factor relevante por considerar en el comportamiento del consumidor, debido a que se refiere a la percepción que tienen las personas frente a un producto extranjero, de acuerdo con la etiqueta de su país de origen. El objetivo de la presente investigación es conocer las características del consumidor de vino en Cali (Colombia), una región donde el consumo de esta bebida ha venido en aumento en los últimos años, teniendo en cuenta su nivel de involucramiento y la influencia del país de origen en su decisión de compra.

User profiling for Chinese super-new generation wine consumers based on improved density peak clustering algorithm

PurposeFor a better understanding of the preferences and differences of young consumers in emerging wine markets, this study aims to propose a clustering method to segment the super-new generation wine consumers based on their sensitivity to wine brand, origin and price and then conduct user profiles for segmented consumer groups from the perspectives of demographic attributes, eating habits and wine sensory attribute preferences.Design/methodology/approachWe first proposed a consumer clustering perspective based on their sensitivity to wine brand, origin and price and then conducted an adaptive density peak and label propagation layer-by-layer (ADPLP) clustering algorithm to segment consumers, which improved the issues of wrong centers' selection and inaccurate classification of remaining sample points for traditional DPC (DPeak clustering algorithm). Then, we built a consumer profile system from the perspectives of demographic attributes, eating habits and wine sensory attribute preferences for segmented consumer groups.FindingsIn this study, 10 typical public datasets and 6 basic test algorithms are used to evaluate the proposed method, and the results showed that the ADPLP algorithm was optimal or suboptimal on 10 datasets with accuracy above 0.78. The average improvement in accuracy over the base DPC algorithm is 0.184. As an outcome of the wine consumer profiles, sensitive consumers prefer wines with medium prices of 100–400 CNY and more personalized brands and origins, while casual consumers are fond of popular brands, popular origins and low prices within 50 CNY. The wine sensory attributes preferred by super-new generation consumers are red, semi-dry, semi-sweet, still, fresh tasting, fruity, floral and low acid.Practical implicationsYoung Chinese consumers are the main driver of wine consumption in the future. This paper provides a tool for decision-makers and marketers to identify the preferences of young consumers quickly which is meaningful and helpful for wine marketing.Originality/valueIn this study, the ADPLP algorithm was introduced for the first time. Subsequently, the user profile label system was constructed for segmented consumers to highlight their characteristics and demand partiality from three aspects: demographic characteristics, consumers' eating habits and consumers' preferences for wine attributes. Moreover, the ADPLP algorithm can be considered for user profiles on other alcoholic products.

Exploring the influence of emotionality and expertise on online wine reviews: does greater knowledge lead to less review?

PurposeWine producers and marketing professionals increasingly recognize the significance of online wine reviews. Emotions have long been acknowledged as influential in online review behaviors. However, considering the multisensory nature of the wine experience, consumers’ wine expertise also plays a substantial role. Hence, this study aims to examine the online review behaviors exhibited by wine consumers through the dual lens of wine expertise and emotionality.Design/methodology/approachTwo studies were conducted to address the research question. Study 1 explored the relationship among expertise, emotionality and review behaviors using a panel data model, with a data set consisting of 4,600,922 reviews from Vivino.com. Study 2 used a multigroup structural equation modeling (SEM) analysis using data obtained from an online survey. Study 2 aimed to investigate the interactive impact of emotionality and expertise on online review intention mediated by customer engagement.FindingsThe findings from Study 1 demonstrated a positive correlation between emotionality and online wine reviews. In addition, expertise displayed a bell-shaped relationship with both emotionality and online wine reviews. Study 2, in turn, uncovered that novices and experts experienced a direct influence of emotionality on their review intentions. In contrast, for those classified as ordinary, the influence of emotionality on review intention occurred indirectly through the mediation of customer engagement.Originality/valueThis paper extends the current literature on online wine review by integrating the effect of emotion and expertise on online wine review behaviors, expanding the examination of Dunning–Kruger effect in the wine literature. It also adds value by introducing emotionality and the Evaluative Lexicon into the hospitality literature, extending the measurement of emotion from valence and extremity to a third dimension, emotionality, in hospitality and wine domains.

Understanding Sparkling Wine Consumers and Purchase Cues: A Wine Involvement Perspective

Research on sparkling wine (SW) consumers, their market segmentation, and how they use purchase cues is relatively sparse compared to that for table wine, despite the substantial growth in sparkling wine in recent years. We address these gaps and particularly how the importance of SW purchase cues varies with wine involvement in an online survey of SW consumers from Ontario, Canada (n = 1011). Thirty intrinsic and extrinsic purchase cues were rated for importance (n = 609), and wine involvement was determined using the shortened version of the wine involvement scale. Overall, consumers rated (in descending order) price, flavour, quality, country, and sweetness level as the most important purchase cues, whereas several extrinsic factors, including bottle colour and shape, awards won, and vintage were of low importance. Females were 1.4 times more likely than males to cite target end use as the most important purchase cue. We further show that SW consumers can be segmented into three wine involvement categories (low, medium, high) which vary across multiple demographic, consumption, knowledge, and preference measures (n = 1003). Notably, the importance of six purchase cue categories (manufacture, price, endorsements, parentage, prestige/reputation, and place) varied with wine involvement (n = 609). These findings provide timely guidance for marketers and retailers seeking to align their products and communications with the needs and perceptions of SW consumers.

Exploring the Impact of Phonetic Pronunciation Guides on Wine Choice and Perceived Sophistication

This study delves into an often-overlooked aspect of wine consumer decision-making – the desire to appear knowledgeable in social settings. Focusing on Texas wines, which are often less well known and more intimidating to say aloud, an exploratory survey examined the impact of phonetic guides on respondents’ choice of wine off a menu. Analysis through nominal logistic regression revealed the presence of phonetic guides as the most significant predictor, suggesting consumers feel pressure to appear knowledgeable or sophisticated. Respondents who were provided menus with phonetic spellings were more inclined to choose wines with intimidating names. The inclusion of phonetic spellings not only reduced the perceived risk in ordering the wine but also served an educational role. By recognizing the influence of social factors, such as a consumer’s perceived sophistication, this study recommends establishments enhance menus with phonetic guides to empower consumers in making confident, informed choices.

Point and interval forecasting for wine prices: an approach based on artificial intelligence

PurposeWith the rise in wine consumption, accurate wine price forecasts have significantly impacted restaurant and hotel purchasing decisions and inventory management. This study aims to develop a precise and effective wine price point and interval forecasting model.Design/methodology/approachThe proposed forecast model uses an improved hybrid kernel extreme learning machine with an attention mechanism and a multi-objective swarm intelligent optimization algorithm to produce more accurate price estimates. To the best of the authors’ knowledge, this is the first attempt at applying artificial intelligence techniques to improve wine price prediction. Additionally, an effective method for predicting price intervals was constructed by leveraging the characteristics of the error distribution. This approach facilitates quantifying the uncertainty of wine price fluctuations, thus rendering decision-making by relevant practitioners more reliable and controllable.FindingsThe empirical findings indicated that the proposed forecast model provides accurate wine price predictions and reliable uncertainty analysis results. Compared with the benchmark models, the proposed model exhibited superiority in both one-step- and multi-step-ahead forecasts. Meanwhile, the model provides new evidence from artificial intelligence to explain wine prices and understand their driving factors.Originality/valueThis study is a pioneering attempt to evaluate the applicability and effectiveness of advanced artificial intelligence techniques in wine price forecasts. The proposed forecast model not only provides useful options for wine price forecasting but also introduces an innovative addition to existing forecasting research methods and literature.

Exploring Consumer Preferences for Locally Produced Wine in the Tanzanian Market: Evidence from Wine Consumers in Dodoma City

In most grape-producing countries, the local wine industry faces intense competition due to the introduction of new foreign wines into the local market and changes in wine consumption and consumer preferences for wines. The same has been observed in the Tanzanian wine industry. The study aims to explore the dynamics of consumer preferences toward locally-produced wine. Data were collected from 200 respondents in Dodoma town through snowball and convenience sampling. Qualitative and quantitative types of data were used. Primary data were collected in the field using field observations, a key informant interview checklist, and structured questionnaires using KoBoToolbox. Secondary data were collected by reviewing different published and unpublished materials, such as reviews and reports regarding consumer preferences for local wine. The research revealed that most consumers consider color, taste, income, brand, and price attributes when selecting wines. Furthermore, the study observed that age, income, marital status, price, wine color, packaging and taste significantly influenced consumers' preference for purchasing locally produced wines compared to other factors included in the model. However, attributes such as geographical origin, vintage and grape variety were not considered in the selection of the wines. The study recommends that local wine producers consider consumers' preferred attributes to increase sales. Local marketers and brand managers should also formulate and employ several positioning, market segmentation and targeting strategies that can help them compete effectively with imported wines.

Moderate wine consumption measured using the biomarker urinary tartaric acid concentration decreases inflammatory mediators related to atherosclerosis.

Several studies suggest that moderate wine consumption, particularly red wine, may have benefits for cardiovascular health. Red wine contains a variety of bioactive compounds, including polyphenols like phenolic acids, which have demonstrated anti-inflammatory effects in experimental models. The aim of this study was to assess the anti-inflammatory properties of wine, measured as urinary tartaric acid, a new biomarker of wine consumption. One-year longitudinal study that included 217 participants from the PREDIMED trial. Plasma inflammatory biomarkers and urinary tartaric acid were analyzed using xMAP technology and high-performance liquid chromatography, respectively. Multivariable regression analyses were performed to assess the relationship between variations over 1-year in urinary tartaric acid concentrations and 1-year changes in serum inflammatory molecules, including adhesion cell molecules, interleukine-6, tumour necrosis factor alpha, and monocyte chemotactic protein 1. Three categories were built according to tertiles of 1-y changes in urinary tartaric acid. Using a ROC curve, urinary tartaric acid was corroborated as a reliable biomarker of wine consumption (AUC = 0.818 (95% CI: 0.76; 0.87). In the continuous analysis, participants with higher increases in tartaric acid significantly reduced their concentrations in soluble vascular adhesion molecule (sVCAM-1) after 1-year of follow-up (-0.20 (-0.38; -9,93) ng/mL per 1-SD increment, p-value = 0.031). Moreover, tertiles 2 and 3 of 1-year changes in tartaric acid presented a significant reduction in soluble intercellular cell adhesion molecule (sICAM-1) as compared to tertile 1 (-0.31 (-0.52; -0.10) ng/mL, p-value = 0.014 and -0.29 (-0.52; -0.07) ng/mL, p-value = 0.023, respectively). Participants in the third tertile also exhibited a reduced concentration of sVCAM-1 compared to those in the first tertile (-0.31 (-0.55; -0.06) ng/mL, p-value = 0.035). Our findings suggest that wine consumption is associated with lower levels of inflammation due to the anti-inflammatory properties of wine compounds.

Symposium Introduction: Recent Progress and Current Challenges in Wine Analytical Sciences.

Oenology, behind the more visible social and convivial aspects associated with the consumption of wine and spirits, has great complexity due to the coexistence of countless different styles of artisanal products, linked to the diversity of places grapes are grown and wine is produced, and its global distribution. Premium wine is not a commodity. To scientifically support such complexity requires an extremely rigorous and diversified scientific expertise, capable of supporting the continuous improvement of processes and products that are developed, evaluated, and offered on international markets. Rigorous chemical and sensory analyses are essential to this continuous process of improvement, and for several decades now have regularly brought together a large community of researchers from multidisciplinary backgrounds to share, discuss, and harmonize their knowledge and experience of wines. The 12th edition of In Vino Analytica Scientia 2022 was held in Neustadt, Germany, in July 2022. The conference was attended by over 240 delegates, from 23 nationalities, who shared different aspects of wine and spirits research, with 9 key note lectures; 37 full talks; 36 short communications, and over 200 posters. This special issue is a collection of full papers from a selection of contributed oral presentations and posters presented at the conference.

Unveiling the Tapestry of Chinese Wine Consumers: A Quantitative Investigation of Influencing Factors and Consumer Segmentation

Purpose: This study investigates the key influencing factors of wine purchasing behaviour of the Chinese wine consumer market and explores the relevant parameters influencing cluster building among Chinese wine buyers. Design: The data for this study was obtained through a survey distributed to wine company followers from the Changyu Pioneer Wine Co. Inc., on WeChat resulting in the collection and analysis of 1,535 useable valid responses. Findings: Six clusters are identifiable; they differ significantly with various individual characteristics and wine purchasing behaviour. The choice between foreign and domestic wine is a significant factor in understanding wine preferences. The importance of wine attributes (colour, taste, and distribution channels) varied among different groups, indicating that these factors operate differently across populations. Variables pertaining to having experience abroad distinguished and separated younger cohorts. Participants from metropolitan areas, female participants, and younger age groups provided valuable insights into the preferences of the younger generation. Practical implications: Our findings emphasize the importance of considering factors beyond initial wine brand and individual characteristics when studying wine consumer behaviour. Elements such as taste preferences, distribution channels, cultural influences, and personal experiences play a substantial role in shaping wine preferences. Understanding the impact of these factors enables the development of strategies and offerings that better align with the diverse needs and preferences of Chinese wine consumers.
