Attitudes towards natural wines among Spanish winemakers: Relationship with environmental awareness.

There is an important movement in the wine industry towards the production of alternative and more sustainable wines. Natural wine (NW) is a controversial category of alternative wines, which needs to be further explored. Given the role of technical experts as opinion leaders, the present work aims to explore the attitudes of Spanish winemakers towards NW and their relationship with their overall environmental awareness. Therefore, 307 Spanish winemakers completed a questionnaire to evaluate: (1) their attitudes towards NW by scoring their agreement with 31 statements, (2) their ecological awareness by evaluating 11 items, (3) their frequency of consumption and interest towards NW, and (4) their sociodemographic profile and general information about wine production. PCA with varimax rotation calculated on 28 of the 31 statements related to their attitudes showed six independent dimensions. Further hierarchical cluster analysis calculated with the six dimensions showed five clusters of wine experts with different attitudes towards NW. Results show that there is a major negative attitude towards the flavour of NW, their ageing capacity and their quality-price ratio, but a positive one in terms of economic impact for the wine industry. Aspects related to the role of NW in tradition, social identity, ecology, health, artisanal production and economic feasibility mark differential attitudes. Interestingly, the dimension related to winemakers attitude towards tradition, social identity, and ecology of NW was positively correlated with their overall ecological awareness and thus their life style. This paper sheds light in the understanding of the behaviour of Spanish winemakers regarding ecological transition and provides tools for policymaking regarding NW certification.

Tell us how you taste wine, and we will tell you what kind of expert you are!

Whether "gurus", "emperor" or "influencers", wine consumers need references to help them choosing and buying wines. Given the diversity of possible sources (reviews from wine guides, wine merchants'recommendations or back wine label), where should they turn? Are all wine experts consensual in the way they taste wines? Do they differ depending on their domain of expertise: wine makers, sellers, or critics? This study aimed at understanding how experts apprehend wine tasting in relation to their professional objectives. A mixed design strategy combining content analysis of personal narratives of renowned wine experts with semi-structured interviews of wine professionals was used. Results confirmed that wine experts shared a common way of tasting wines, although their objectives and the way they report their wine tasting experiences differ according to their professional activities. Makers transcribe their perceptions by a list of sensory and technical-based terms focused on the absence or presence of wine defects to assess technical acceptability, Sellers are storytellers generating appeal and pleasure for consumers, and Critics write positive and metaphoric reviews to better highlight the best samples they taste. This raises new questions for the industry about the way in which wines are tasted, a routine practice that is internationally followed by wine professionals, but which may need to be renewed. Combining different data sources appeared to be a promising way to gain in-depth information in exploratory research.

How has COVID-19, lockdown and social distancing changed alcohol drinking patterns? A cross-cultural perspective between britons and spaniards.

During the early months of 2020, the world experienced a novel, violent, and relentless pandemic era. By the end of the year more than seventy-seven million cases of COVID-19 had been reported around the globe. Due to it being a highly contagious disease, the recommended measures adopted by most nations to prevent infection include social distancing and quarantine. How did these measures affect people's relationship with alcohol consumption in cultures where alcohol plays an important social role? A questionnaire-based study, designed to follow the drinking behaviour of people before and during lockdown was applied to two different cultural groups impacted by the pandemic during the strict phase of lockdown. These are the British and Spanish populations (179 participants from each country were interviewed). Considering the frequency of consumption of the alcoholic beverages evaluated (wine, beer, cider, whisky and spirits), the results showed that a significant lockdown*country interaction was observed. Overall, Spanish participants consumed alcoholic beverages less frequently during lockdown than before, while British participants reported no change in their consumption habits. Spaniards' decrease in alcohol consumption is related to the absence of a social contexts while Britons seems to have adapted their consumption to the modified context. Results suggest that, alcohol consumption is a central core of the British culture, while for the Spanish, socialization is more a cultural characteristic than the alcohol itself.

Meat replacer? No thanks! The clash between naturalness and processing: An explorative study of the perception of plant-based foods.

A shift towards a plant-based diet is desired to promote sustainability, improve health, and minimize animal suffering. However, many consumers are not willing to make such a transition, because of attachment to meat and unwillingness to change habits. The present work explored the perception of Norwegian and French consumers' attitudes, barriers and opportunities to increase the likelihood of a shift in diet. Three creative focus groups (CFGs), using interactive tasks such as photo-collage, projective mapping, story completion and third person technique, were run with omnivorous adult consumers in each country. CFGs gathers undirected feedback, providing less biased responses than other exploration methods, related to e.g. social norms. In both countries, results were in general lines comparable. Nutritional knowledge was low regarding vegetable proteins; familiar sources of protein were mostly animal. There is a strong gap between respondents' desired behaviour (balancing nutrition, eating less meat) and their actual behaviour: meat is very important, and the menu is often organized around it. Consumers are curious about vegetable sources of protein, but major constraints were hedonics in France, and convenience in Norway. The main barrier to a shift in diet is the lack of knowledge on how to prepare plant-based meals. Many participants find a conflict between health & sustainability in industrial products, perceiving them as highly processed and suggesting that meat replacers might not be a straightforward way to drive omnivorous consumers to shift to a more plant-based diet.

To fear the unknown: Covid-19 confinement, fear, and food choice.

The coronavirus outbreak in December 2019 completely changed the dynamic of consumption in different sectors of industry. The food and beverage industries have been profoundly affected, from production, to modifications in consumers' choices. Among the different reasons behind those modifications is confinement, which forces consumers to stay at home for an extended period and just go out to perform essential tasks, such as going to the supermarket. We hypothesized that this new dynamic of consumption could create a situation of fear that changes food choice. To test this hypothesis, two studies were conducted in three countries with a different degree of confinement: Mexico (flexible), Spain (strict), and Peru (hard). Study one consisted of a free association task with 60 participants in each country with the inductor word "coronavirus and food". The different associations served as the basis to build a structured questionnaire, which was used in the second study focused on fear and food choice. The second study was applied to 450 participants in the same three countries. Results showed that fear can be separated into nine dimensions: social, emotional, food supply, government, basic needs, food-delivery, overeating, immunity, and family conflicts. The participants could also be clustered into four different groups that differ in their country of origin and sex, but also in their food choice. Overall, the results showed that fear influenced consumer's food choices during a confinement period.

In-mouth attributes driving perceived quality of Pinot noir wines: Sensory and chemical characterisation.

We investigated perception of mouthfeel in Pinot noir wines and its physicochemical determinants. Seventeen wine professionals judged 18 Pinot noir wines via two tasting tasks, Descriptive Rating and Directed Sorting, the latter based on perception of in-mouth attributes. Selected chemical measures of the same 18 wines were determined. Sensory results demonstrated that mouthfeel attributes driving high quality were smoothness/silky/velvety, volume/fullness/roundness, overall body, and viscosity/mouth-coating, while the taste of bitterness and perceived tannin harshness drove low quality judgments. Perceived astringency and expressions of tannin (e.g., soft; harsh; fine) drove sorting behaviour of participants. Partial least squares regression (PLSR) was used to associate perceived in-mouth phenomena and chemical composition. The phenolic profile, in particular tannin concentration and structure, was the most important predictor of astringency and its sub-components. These results have important implications for wine producers aiming to enhance perceived quality in their Pinot noir wines.

The Impact of "Wine Country of Origin" on the Perception of Wines by South African and French Wine Consumers: A Cross-Cultural Comparison.

Culture is an important factor that influences how marketing interacts with food choice. This study aims at exploring the effect of consumers' Country of Origin (COO) on wine representations and perception using Chenin blanc as a model. The first objective was to evaluate the role of origin in the construction of the representation. We used the theoretical framework of social representation to compare South African (SA) and French consumers' representations via a word association task. The results indicated that SA representations are dominated by consumers' experience of the wine (sensory and emotional dimensions), whereas French representations are dominated by the wine itself, in particular its origin and mode of consumption. The second objective was to evaluate the effect of origin on wine categorization in two conditions: with and without information concerning the two geographical origins of the samples. Results showed that providing information on the origin of the wines affected French participants more than SA participants. In both conditions, the groups of wines formed in the sorting tasks by SA participants were based on sensory descriptors and appeared not to be impacted by the information on origin. In contrast, providing information on the origin of the wines to French participants led to an increased use of the words "Loire", "South Africa" and "familiar" suggesting a different sorting strategy more deliberately based on the origin of the wines. Our findings have important implications for the marketing and export activities within the wine industry.

Perception of quality and complexity in wine and their links to varietal typicality: An investigation involving Pinot noir wine and professional tasters.

Quality and complexity are abstract terms employed frequently to describe a wine's overall attributes. In the present study, we investigated: (i) attributes driving wine professionals' judgments of quality and complexity in Pinot noir wines; (ii) the relation between these two abstract concepts; and (iii) association of each concept with varietal typicality. Twenty-two wine professionals evaluated 18 New Zealand Pinot noir wines in both clear and opaque glassware via two sensory tasks, a descriptive rating task and an 8-attribute, perceived complexity questionnaire. Sensory data were associated with wine UV-spectrophotometry colour measures to aid interpretation of the influence of tasting-glass colour. Results demonstrated the key drivers of perceived quality were descriptors varietal typicality, expressiveness, overall structure, and attractive fruit aromatics, along with complexity questionnaire attributes of harmony, balance and number of identifiable flavours. Reductive notes drove low-quality judgments. Data show that quality and complexity were positively associated concepts and that both were linked positively with varietal typicality. Visual influence was not a major driver of wine professionals' judgments but being able to see a wine's colour influenced tasters' judgments to wines at each end of the price/quality spectrum. We discuss the results in terms of cognitive phenomena associated with judgments by those with domain-specific expertise.

How the country-of-origin impacts wine traders' mental representation about wines: A study in a world wine trade fair.

Using data collected at a world wine trade fair, we study how the country-of-origin impacts wine traders' mental representation about wines. In the analysis we use traditional exporters in Old (France) and New (Argentina) world wine countries in comparison to non-traditional exporters in Old (Switzerland) and New (Brazil) world wine countries. Three main findings are reported. First, the country-of-origin of wines was more important on guiding participants' representations, than the category of countries the traders came from. Second, participants' evocations were more precise and specific for traditional wine-exporting countries than for less traditional wine exporting countries. Finally, the lack of traders' knowledge of wines from non-traditional wine-exporting countries produced associations and beliefs related to the image of the country itself. Our findings have important implications for the marketing and export activities of the wine industry.

Looking at non-sensory factors underlying consumers' perception of smoked bacon.

Smoked bacon is a food consumed everywhere and previous work has focused on the sensory properties and acceptability of the product. However, little attention has been given to the non-sensory factors that drive sensory and hedonic perception of this product. In this context, the aim of this work was to study the influence of non-sensory factors on consumer behavior towards smoked bacon, using projective mapping coupled with conjoint analysis. Eight visual stimuli were created using a full factorial design with three factors (convenience, healthiness, and context of consumption), at two levels each. Ninety-five consumers positioned the stimuli in a two-dimensional space considering their similarities and differences, and then, rated their expected liking and purchase intention. According to the projective mapping, consumers based the representation of the stimuli on the three factors under study, but conjoint analysis indicated that healthiness was the most important factor, followed by the context of consumption and convenience. The findings of this study may help in the selection of future strategies in the process of food development, in order to launch products with greater chance of success in the market.

Fourteen ethyl esters of wine can be replaced by simpler ester vectors without compromising quality but at the expense of increasing aroma concentration.

Aroma contribution of individual esters has been studied in complex mixtures mimicking red wine models. A mixture containing 14 ethyl esters at concentrations found in wine (V1) was prepared and kept as reference. Isointense and qualitatively similar aroma vectors with a reduced number of esters (V2-V7) were prepared. Those vectors were introduced in two reconstituted wines to assess whether simpler vectors could replace V1 without compromising wine quality. In the simpler young wine model, V1 could be replaced by a vector containing just 3 odorants (ethyl 2-methylbutyrate, ethyl butyrate and hexanoate). In the oaky model, a vector containing just ethyl 2-methylbutyrate (V7) could replace V1 without any discernible sensory change. Results also reveal that sub- or perithreshold odorants play outstanding roles on the overall odour intensity of the mixture and that aroma simplification concomitantly implies an increase in the amount of odorant required to keep the intensity of the aroma vector.

Impact of the content and size of NaCl on dynamic sensory profile and instrumental texture of beef burgers.

The objectives of this study were to determine the effect of reducing the content and size of NaCl on the instrumental texture and dynamic sensory profile, and to determine the temporal drivers of liking (TDL). The reduction of the NaCl content decreased the hardness and chewiness parameters, and affected the dynamic sensory profile of the product. The NaCl reduction (<1.0% NaCl) was related to a higher incidence of the attributes off-flavor and dry. In general, the overall liking was driven by the juicy and tasty attributes, the latter being associated with the presence of the sensory attributes salty and seasoned and the texture parameters hardness and chewiness. According to the results, among the treatments with NaCl reduction, the beef burger added with 1.0% micronized salt stood out, since it did not affect considerably the texture parameters, the dynamic sensory profile during chewing and the consumers' liking.

How a combination of two contradicting concepts is represented: The representation of premium instant noodles and premium yogurts by different age groups.

This study was conducted to investigate the representation of the association between two contradicting concepts: premium and low-priced foods (instant noodles and yogurt) by different age group. Subjects undertook free word association tasks relating to the cue words premium, instant noodles, yogurts, premium instant noodles, premium yogurts and rated their importance. Subjects comprised 150 individuals from three different age groups: the adolescents (AD), aged 13-18 years; the young adults (YA), aged 19-29 years;, and the middle-aged adults (MA), aged >30-years. Words elicited from subjects were classified into central core and peripheral elements according to their frequency of occurrence and their importance. Representations of instant noodle, premium noodles, yogurt and premium yogurt were compared to examine whether the use of the term premium has a food-specific influence or a universal effect on the development of representations. Differences in representations among age groups were investigated using correspondence analysis. The central core of both premium instant noodles and premium yogurt consisted of delicious, health, and good for health. In addition, high quality, expensive, price, and good were transferred from the representation of premium to both those of yogurt and instant noodles. This suggests that the addition of the term premium has a universal effect across food items. Addition of premium to instant noodle and yogurt increased negative emotions. The representation of premium instant noodles and premium yogurt significantly differed by age. MA associated premium food items with price while YA related them with quality aspects. These differences seemed to be associated with the experiences that each group had gathered with regard to the terms premium, instant noodles, and yogurt.

Reducing the sodium content without modifying the quality of beef burgers by adding micronized salt.

This study determined the effect of the incorporation of micronized salt on physicochemical, yield and consumer's sensory characteristics of beef burger. The micronized salt was obtained by sieving the commercial salt in a 60-mesh stainless steel sieve. The commercial (regular salt) and micronized salt presented differences in the mean size, size distribution and bulk density. Half of the amount of the micronized salt was mixed with pork back fat, and the other half was added to the meat batter in the beef burger manufacture. A Pivot profile method was used with consumers to describe the sensory properties of the burger samples (ranging from 0.5% to 1.5% NaCl). The Pivot profile data revealed that treatments with 0.75% and 0.5% micronized salt were mainly characterized as dry, besides showing the highest cooking loss and diameter reduction. However, beef burgers with 1.0% micronized salt and 1.5% regular salt had similar perceived salty taste. In terms of salt reduction, the results indicated that it would be possible to reduce salt from 1.5% to 1.0% when using micronized salt, without affecting the pH, color parameters, yield properties and some sensory characteristics of the burger, such as salty, tasty, juicy, fatty, and spicy. Therefore, this strategy promises great potential for industrial application in products that contain lipids in their composition, such as meat products.

Prospects for Food Fermentation in South-East Asia, Topics From the Tropical Fermentation and Biotechnology Network at the End of the AsiFood Erasmus+Project.

Fermentation has been used for centuries to produce food in South-East Asia and some foods of this region are famous in the whole world. However, in the twenty first century, issues like food safety and quality must be addressed in a world changing from local business to globalization. In Western countries, the answer to these questions has been made through hygienisation, generalization of the use of starters, specialization of agriculture and use of long-distance transportation. This may have resulted in a loss in the taste and typicity of the products, in an extensive use of antibiotics and other chemicals and eventually, in a loss in the confidence of consumers to the products. The challenges awaiting fermentation in South-East Asia are thus to improve safety and quality in a sustainable system producing tasty and typical fermented products and valorising by-products. At the end of the "AsiFood Erasmus+ project" (www.asifood.org), the goal of this paper is to present and discuss these challenges as addressed by the Tropical Fermentation Network, a group of researchers from universities, research centers and companies in Asia and Europe. This paper presents current actions and prospects on hygienic, environmental, sensorial and nutritional qualities of traditional fermented food including screening of functional bacteria and starters, food safety strategies, research for new antimicrobial compounds, development of more sustainable fermentations and valorisation of by-products. A specificity of this network is also the multidisciplinary approach dealing with microbiology, food, chemical, sensorial, and genetic analyses, biotechnology, food supply chain, consumers and ethnology.

Early-blind Individuals Show Impaired Performance in Wine Odor Categorization.

Blind individuals display superior sensory abilities in other modalities, yet results remain contradictory regarding their performance on olfactory tasks. Using complex ecological olfactory tasks, we evaluated the impact of blindness on olfactory performance. We tested 12 early-blind individuals (M = 49, SD = 13.09) and 12 sighted controls (M = 49, SD = 14.31) who were all blindfolded. Based solely on the wine odors, participants evaluated 24 pairs of wine and determined if both samples belonged to the same category (red wine, white wine, or rosé wine) or not (odor categorization), and if so, whether they were identical or not (odor differentiation). Then, they had to classify 15 different wines (5 red, 5 white and 5 rosé) into red, white, and rosé wines (odor classification). Blind individuals (d': M = 1.3, SD = 1.2) presented lower scores compared to sighted controls (M = 2.2 SD = 0.8; p < .05) in the odor categorization task, but no group difference was observed for the other tasks. For all participants, red wine odors were the easiest to classify (1.8 ±â€¯1.0), followed by white wine odors (0.5 ±â€¯0.6) and finally rosé wine odors (blind and sighted; F[2; 44] = 11.9, p < .001). In summary, early-blind individuals had a harder time to categorize wine odors. This could be explained by a different construction of internal reference categories for wine in early-blind individuals. Finally, this research is in line with the notion of the absence of higher olfactory sensitivity in blind individuals.

The building blocks of drinking experience across men and women: A case study with craft and industrial beers.

In today's market, every product seems to be marked by the label of "experience". It is expected that successful products give the consumer "extraordinary experiences". The research in consumption experience is growing, but much work still needs to be done to understand the food and beverage experience. A qualitative study was conducted using contextual focus groups to explore the building blocks of consumers' drinking experience of industrial and craft beers. The results show that drinking experience is shaped by our cognitive, sensory or affective systems, especially during the core consumption experience. Elements such as attitudes, consumption habits, and individual versus social consumption, shopping experience and product benefits are also responsible for shaping the experience, but are more relevant during the pre-consumption or post-consumption experience. Gender differences occur more frequently in the affective experience, as women search more for relaxation while men for excitement and stimulation while drinking beer. When comparing industrial users versus craft, in the latter the cognitive and shopping experiences are more relevant. Overall, the results showed that the drinking experience of beers can be studied as a function of the salient human system used during product interaction, and this systems act as the building blocks of the drinking experience of beer. This information can be applied in consumer research studies to further study the experiential differences across products and consumers.

Sensory and chemical drivers of wine minerality aroma: An application to Chablis wines.

The goal of this work was to evaluate the effect of vineyard position on the minerality of wines and to establish relationships between minerality scores, sensory descriptors and chemical composition. Sensory analyses included minerality rating and free description performed by wine professionals under two conditions: orthonasal olfaction alone and global tasting. Chemical characterization included analysis of major and minor volatile compounds, volatile sulphur compounds, mercaptans, metals, anions and cations. Results showed a significant effect of the river bank on wine minerality scores only in the orthonasal olfaction condition, samples from the left being more mineral than those from the right bank. Methanethiol, involved in shellfish aroma, was significantly higher in wines from the left (more mineral) than from the right bank. Contrary, copper levels, related to lower levels of free MeSH, and norisoprenoids, responsible for white fruit and floral aromas, were higher in wines from the right bank (less mineral).
