Why consumers drink natural wine? Consumer perception and information about natural wine


Similar to other foods, the concept of natural wine is much debated due to the lack of a clear and regulated definition, leading to a proliferation of heterogeneous norms and standards proposed from different natural wine associations at national levels. The current study explored the aspects which mediate individuals’ information and perception of natural wine, and the rationale behind natural wine consumption behavior among Italian (n = 501) and Spanish (n = 527) regular wine consumers. The results reveal a quite low self-reported degree of perceived information by Italian respondents and slightly higher levels among Spanish ones. The key drivers of natural wine consumption in both countries are wine consumption frequency, information, and natural product interest. In contrast, higher wine involvement levels decrease natural wine consumption frequency in both Italy and Spain. The findings also show that different perceptions lead to diverse motivations, suggesting the need for more homogeneous standards to mitigate the level of information asymmetry currently on the market.


The growing awareness of public opinion about the linkage between food and health, as well as on the negative effects that traditional food production practices have on environmental resources, has triggered consumers to be more selective and pay more attention to which components and ingredients are used in the food products they eat in everyday life (Asioli et al. 2017).

Consequently, the demand for natural products has grown considerably over the last decade among consumers. The notion of “natural” has become one of the leading label claims on new food products launched to satisfy new consumer demands and market niches (Roman et al. 2017; Hemmerling et al. 2016). However, a universally accepted definition of food naturalness does not exist, and thus, the naturalness of a food product is still a rather vague concept (Roman et al. 2017; Rozin 2006). Undoubtedly, naturalness leads consumers to perceive food products as healthier and more environmentally friendly than conventional ones (Rozin et al. 2012; Caracciolo et al. 2019) but also tastier, evoking an enhanced hedonic experience (Chambers and Castro 2018; Siegrist and Hartmann 2020).

The search for naturalness has also affected the wine market (Wine Intelligence 2021). Consumer preferences are gradually more influenced by aspects of wine linked to personal healthiness and product sustainability, and this in turn impacts the quality differentiation strategies developed by firms (Pomarici and Vecchio 2019; Schäufele and Hamm 2017). Indeed, the increasing amount of low-intervention, additive, and processing aid-free wines represents a strong trend in several important markets (Wine Intelligence 2021). Natural wine consumption has increased especially among more conscious and responsible consumers, as suggested by recent empirical researches (Galati et al. 2019; Migliore et al. 2020). Furthermore, various producers’ associations and organizations are actively promoting natural wine, among them are the Asociación de Productores de Vino Natural and Vella Terra in Spain and Triple A, Viniveri, VinNatur, and Vignaioli Artigianali Naturali (VAN) in Italy (Catellani 2015).

Natural wines are also attracting increased attention among wine critics, giving rise to a surge in books, specialized events, and films about them (Feiring and Choksi 2019; Nossiter 2019; Legeron 2018; Goode and Harrop 2011). Similar to other foods, however, the concept of natural wine is highly debated in the literature due to the lack of a clear and regulated definition. This has led to a proliferation of heterogeneous norms and standards proposed from different natural wine associations at national levels (Alonso González and Parga-Dans 2020; Forbes et al. 2009). Therefore, to date, it is difficult to outline the boundaries of this concept due to the different production philosophies that natural winemakers promote, which have triggered debates among natural winemakers themselves.

Therefore, natural wine should be considered a social movement involving consumers and producers rather than a regulated form of agricultural production (Maykish et al. 2021; Urdapilleta et al. 2021). Only France has recently recognized natural wine as a distinct category and certified it under the denomination Vin Méthode Nature. However, this certification has prompted a heated debate in the European Commission as other EU countries do not agree with the French certificationFootnote 1, considering it a form of unfair competition against their own wine sectors. This uncertainty about the meaning of natural wine affects also consumer’s perceptions. According to the existing literature, wine is generally perceived to be a natural and environmentally friendly product, as consumers often assume it only includes grapes (De Salvo et al. 2019; Grunert et al. 2018), showing low knowledge about the ingredients, additives, and processing aids that may be used in the production of wine (Pabst et al. 2019; Grunert et al. 2018). Even wine critics tend to associate wine with nature in their tasting rhetoric, with the aim of attracting consumer interest (Black 2013). This is also due to the information asymmetry that dominates the wine sector worldwide (Parga-Dans and Alonso González 2018). The asymmetry derives from the fact that wine has been historically exempted from the mandatory ingredients list other than those that may have an allergenic effect (e.g., sulfites, egg, or fish), generating disinformation and confusion among consumers (Pabst et al. 2021). Nonetheless, according to the latest surveys, European consumers show a clear concern for food additives and residues (EFSA 2019), which would generate a market niche for natural wine in case it would be recognized as such.

In addition, previous studies showed that consumers tend to associate natural wine conceptualization with organic (Urdapilleta et al. 2021), tend to mistake natural with organic or biodynamic (Delmas and Lessem 2017; Sogari et al. 2016), or to connect the naturalness of wine with the presence of an eco-label (D’Amico et al. 2016). In this context, an in-depth analysis of how consumers perceive natural wine is critical in order to mitigate the level of information asymmetry currently on the market. This could help winemakers, distributors, and retailers to develop more targeted marketing strategies. At the same time, supplementary insights on the drivers of individuals’ natural wine consumption could support policymakers in deciding whether regulating the natural wine labeling and foster tailored communication strategies to better address consumers’ needs and expectations.

In addition, according to Galati et al. (2019), a cross-country study on this topic could be useful in order to reveal possible opportunities to expand this new market segment.

Consequently, the current paper provides insights on the drivers of natural wine consumption, addressing the following research questions: (i) What are the factors affecting consumer perception of natural wine? (ii) To what extent information and psychographic and socio-demographic variables affect consumers’ natural wine consumption?

To this end, a direct survey was performed in Italy and Spain, which according to the International Organization of Vine and Wine (2020) are the two core countries in terms of both wine consumption and production.

Naturalness interest among wine consumers

While natural wine is increasingly acquiring new consumers in many traditional and non-traditional wine-consuming countries (Wine Intelligence 2021), scholars have devoted limited attention to this specific topic. Nevertheless, several studies have focused on the naturalness of wine indirectly, as an aspect that may influence the perception of healthiness or sustainability of wine (Pappalardo et al. 2019; D’Amico et al. 2016; Kelly et al. 2015). Kelley et al. (2015) showed that the presence of the claim “naturally farmed grapes” in the wine back label information positively affected US consumers’ purchasing decisions. In turn, Pappalardo et al. (2019) found that the adoption of production practices related to the higher amount of a natural compound in wine (i.e., resveratrol) increased consumers’ demand led by the perception of healthiness in wine. Similarly, D’Amico et al. (2016) revealed that the naturalness of wine affects the health attitude of consumers and represents a relevant factor influencing consumers’ willingness to pay a premium price for organic wine without added sulfites.

Considering studies that directly investigated consumers’ perception, attitude, and willingness to pay for natural wine, one of the first contributions on the topic is the research from Galati et al. (2019). The authors showed that Italian consumers are willing to pay a premium price for natural wine, especially millennials which are particularly concerned about the environmental and social impacts of their choices. In addition, the authors found that the importance attributed to the label information on ingredient contents and sensory characteristics is positively linked to individuals’ willingness to pay. Furthermore, Galati et al. (2019) highlighted that consumer WTP for natural wines depends on personal attitudes towards healthy products, without additives or additional ingredients.

Recently, Migliore et al. (2020) found that Italian consumers’ interest towards natural wine is strongly affected by individual attitudes towards healthy eating, the environment, and nature, while sensory characteristics and other traditional quality attributes, such as wine color, grape varieties, alcohol content, critics ratings, are not influential. In addition, the authors showed that WTP for natural wine is linked to consumers’ interest towards the organic production method as well as to wine sulfite content; on the contrary, WTP is negatively related to the PDO/PGI certifications. An interesting study realized by Staub et al. (2020) assessed what properties of wine influence the perceived naturalness of consumers from two countries, Switzerland and Australia. The authors reveal that naturalness awareness varies according to the country of origin. In addition, individuals with a high level of wine involvement consider naturalness significantly more important than people with a low level of involvement. Furthermore, Swiss results showed that naturalness was the second most important factor for wine choice over price and grape variety. Urdapilleta et al. (2021) also highlighted that cultural differences, personal involvement, and identification with wine strongly affect the social representations of natural, organic, and conventionally produced wines among French and New Zealanders, as well as between wine professionals and consumers. French consumers see organic and natural wines as healthier and associate them with environmental sustainability, while New Zealanders represent natural wines less positively.

In light of the paucity of specific studies on natural wine, there is a need to better understand this specific target of consumers (Alonso González and Parga-Dans 2020) deepening the numerous aspects which mediate individuals’ information and perception of natural wine, and the rationale behind their consumption behavior.


Questionnaire design and target population

In order to reach the research objectives, a structured questionnaire was distributed via an online survey management software in Italy and Spain between September and November 2020. Individuals aged between 18 and 70 that consume wine at least once a month were eligible to take part in the survey. Randomization techniques were employed to reduce common method biases associated with online surveys and to enhance the validity of the responses (Vecchio et al. 2020). Individuals participated on a voluntary basis after (1) reading an information sheet in which they were informed about the purposes of the study, (2) advised that the study involved questions about alcoholic beverage consumption, and (3) filled the informed consent form. The research ethics review board of the Spanish National Research Council (CSIC) approved the final questionnaire (approval number 136/2020).

In order to reach the greatest number of responses from the target population, the survey was advertised through wine online forums, wine critics, distributors, and producer associations’ webpages and blogs, social networks, and word of mouth. Respectively 501 wine consumers in Italy and 527 in Spain fully completed the questionnaire.

The questionnaire was divided into five sections: (1) wine consumption habits, (2) natural product interest, (3) perception and information about natural wine, (4) natural wine consumption habits and motivations; and (5) socio-demographic characteristics. Previous research has revealed that consumers tend to mislead natural wines with organic or biodynamic (Delmas and Lessem 2017; Sogari et al. 2016). Thus, to avoid confusion, respondents were shown three pictures with different front and back wine labels, relating to three different types of wine (i.e., organic, biodynamic, and natural) before entering the sections relating to natural wine information, perception, consumption habits, and motivations (namely, sections 4 and 5). The questionnaire was pretested with a pilot sample of 20 individuals in each country in order to check the overall understandability and minor changes were made.

Table 1 provides a summary of the key information collected in the study with the relative measures and literature references. The internal consistency and reliability of the applied scales were measured through Cronbach’s alpha, as reported in the “Results” section.

Table 1 Collected data and measurements applied in the current study

Data analysis

Collected data were analyzed in two consecutive steps. First, a descriptive analysis was performed applying frequency distributions, means, and standard deviations in order to provide a preliminary overview of the general results. For specific variables, a one-way ANOVA was performed in order to detect the differences among Italian and Spanish individuals’ behavior. Subsequently, two ordered logistic regressions were performed to identify the drivers that affect natural wine consumption frequency, one for each country.

In order to use the natural wine consumption motivations as explanatory variables in the ordered logistic regressions, two further summary measures were computed with the application of a principal component analysis (PCA) with a varimax rotation to the original items. The two obtained components (with an eigenvalue greater than 1) summarized over 65% of the original variance (see Table 7 in Appendix). The first component was renamed “sustainability motivation,” summarizing the consumption impetus linked to the healthiness and sustainability of natural wine, as well as its handcrafted origin. The second component summarizes instead the reasons related to better taste, easiness of drinking, and less hangover, thus was named “hedonistic motivation.” All elaborations were performed with the Stata/SE 15.0 software (StataCorp, College Station, TX, USA).


Sample description

Socio-demographic characteristics of both Italian and Spanish samples as well as information related to wine drinking habits are reported in Table 2. The Italian sample includes 501 wine consumers, 54% are men, and the mean age is 37.5 years old; more than 50% of the sample is graduated or holds a master’s degree. The Spanish sample includes 527 wine consumers, and the incidence of men is about 70%; the average age is 44.85 and 79% of respondents graduated or hold a master’s degree. Considering the wine consumption habits, most Italian respondents drink wine several times a week (36.7%) or once a week (12.8%), consuming about two glasses for occasion. As for the degree of wine involvement, Table 2 shows that Italian respondents are quite in agreement with the statement “I don’t need a special occasion to drink wine” (M = 3.66), as well as with the statements “I like giving wine as a gift” (M = 3.59) and “I have a strong interest in wine” (M = 3.55). Considering the attention paid to the labeling information during wine shopping, Italian respondents tend to pay more attention towards back labeling than to the front labeling.

Table 2 Socio-demographic characteristics and wine consumption habits

Twenty-three percent of Spanish respondents drink wine every day and 44.2% several times a week (consuming, on average, about 2.5 glasses for occasion). Spanish consumers are highly involved with wine, as they strongly agree with the statements “I have a strong interest in wine” (M = 4.73) and “I select the wines I purchase very carefully” (M = 4.23). They also claim to be very attentive to wine labeling information; both front and back labels received a mean value of 4.2.

Natural product interest

Respondents’ attitude towards natural products was assessed using six items from the Natural Product Interest scale developed by Roininen et al. (1999) and applied in previous research on a similar topic (Migliore et al. 2020) (Table 3). In Italy, the items with the highest scores are “I try to eat foods that do not contain additives” (M = 3.33) and “I would like to eat only organically grown vegetables” (M = 2.95); however, the mean values for these two statements are higher in Spain (respectively 3.74 and 3.44). In Italy, the item with the lowest score is “Organically grown foods are not better for my health than those grown conventionally” (reversed item, M = 1.94), while in Spain, the lowest score is assigned to the item “I do not care about additives in my daily diet” (M = 1.83).

Table 3 Respondents’ natural product interest, mean values (S.D.)

Natural wine information and perception

In order to analyze the self-perceived information about natural wine, we asked wine consumers to indicate their level of information also with respect to organic and biodynamic wines. Italian wine consumers consider themselves not very informed about the three wines considered. However, they feel more informed about organic wine (M = 2.96) than natural wine (M = 2.88), while biodynamic is in absolute the less known wine. Spanish consumers consider themselves quite informed about organic (M = 3.87) as well as about natural wine (M = 3.65).

In order to investigate the interviewees’ perception of natural wine, we proposed seven items asking respondents to indicate the degree of adherence to their idea of natural wine. As reported in Table 4, Italian consumers perceive natural wine mainly as an environmentally friendly product (M = 3.46), which does not contain additives (M = 3.42) and is made in an artisanal way (M = 3.26). Spanish respondents mostly perceive natural wine as a product that does not contain additives (M = 4.24) and without sulfites (M = 4.11), and also as organic (M = 3.60).

Table 4 Self-reported information and natural wine perception, mean values (S.D.)

Natural wine shopping and consumption behavior

In both countries, the incidence of consumers that stated to consume natural wine is high, respectively almost 69% in Italy and 78% in Spain. However, analyzing the frequency of consumption, as reported in Table 5, Italians drink natural wine more regularly than Spaniards. Indeed, 22.7% of Italian respondents stated to drink natural wine at least once a week, while 15.7% 2–3 times a week and 7.8% on a daily basis. In Spain, respondents stated to drink natural wine mainly at least once a year (35.3%) and at least once a month (33.1%).

Table 5 Natural wine drinking frequency and consumption motivations

Regarding the self-reported motivations of natural wine consumption, in Italy, healthiness results are the core reason (M = 3.60), followed by handcrafted (M = 3.53) and sustainability (M = 3.33). In Spain, the handcrafted is the main reason to consume natural wine (M = 3.65), followed by sustainability (M = 3.49). In both countries, the statement “Natural wine makes me less drunk” and “Natural wine is easier to drink” are the least important motivations.

Drivers of natural wine consumption

In order to explore the drivers that affect natural wine consumption frequency, two ordered logistic regressions were performed considering in each country only individuals who have reported to drink natural wine (i.e., 344 in Italy and 411 in Spain). The frequency of consumption is the dependent variable of the models (Cameron and Trivedi 2005; McFadden 2001), while the explanatory variables (identified by a stepwise selection procedure)Footnote 2 are (i) demographics (gender and age), (ii) variables related to wine drinking behavior (frequency and involvement), (iii) attention towards wine label information (back and front), (iv) self-reported information about natural wine and about organic wine, (v) natural product interest, and (vi) natural wine consumption motivations.

Results from the two ordered logistic regression models are reported as odds ratio with 95% confidence intervals in Table 6. Briefly, an odds ratio greater than 1 indicates that higher values on the independent variable make it more likely that respondents will be in a higher category of the natural wine consumption frequency. An odds ratio lower than 1 indicates that a higher value of independent variable increases the likelihood of participants to be in the current consumption frequency level or lower (Table 8 in Appendix reports coefficients and standard errors).

Table 6 Odds ratio of the selected coefficients (95% CI)

Considering the influence of variables related to wine habits, the overall results show that wine consumption frequency is a key driver of natural wine consumption, both in Italy and in Spain. The more individuals consume wine regularly in general terms, the more they tend to consume natural wine frequently. Contrary, if we consider wine involvement level, we notice that in both countries, the higher level of involvement leads to a lower consumption frequency of natural wine. This suggests that consumers that perceive to be more interested in wine consume natural wine less frequently. Remarkable results arise also in relation to the attention paid by respondents to wine label information. Both in Italy and in Spain, the degree of attention to information on the front label negatively affects the natural wine consumption frequency. In other words, the more consumers are attentive towards front label information, the lower is their frequency of natural wine consumption. Nevertheless, in Spain, back label information attention positively affects natural wine consumption. This is probably due to the fact that generally, back labels hold a greater amount of information on the natural characteristics of wines.

Furthermore, and not surprisingly, natural product interest is an important driver of natural wine consumption in both countries. As reported in Table 6, the higher positive attitude towards natural products increases natural wine consumption frequency, with a similar extent in Italy and Spain. Considering variables specifically related to natural wine, the results show that the degree of self-reported perceived information of natural wine positively affects the consumption frequency, in both Italy and Spain. It is worth highlighting that in Italy, self-reported information of organic wine negatively affects natural wine consumption frequency. This reveals that consumers who think of themselves to be informed about organic wine consume natural wine less regularly.

Natural wine motivations also influence consumption frequency. In particular, in Italy, the reasons linked to the sustainability aspects of natural wine positively affect consumption. In Spain, the frequency of consumption is positively influenced by both sustainability and hedonistic motivations. Considering the influence of individual socio-demographic characteristics, age and gender affect the consumption frequency of natural wine in Italy. In particular, younger consumers tend to consume natural wine more frequently, as well as males as compared to females. On the contrary, socio-demographic variables do not influence natural wine consumption frequency among Spanish respondents.


Results from the present study confirm the soaring interest of Italian and Spanish consumers towards natural wine; indeed, in both countries, the incidence of respondents that self-reported consumption of this product was high. The findings also reveal some differences between Italian and Spanish consumers regarding the drivers that affect natural wine consumption frequency.

According to our outcomes, Italians state to drink natural wine more regularly than Spaniards, although the self-reported degree of information about natural wine is higher in Spain. However, with specific reference to the Spanish market, a recent study from Fernández (2019) showed that the lack of consumer understanding of natural wines is considered a key challenge for Spanish natural wine producers.

Further, consumers in both countries showed a higher level of perceived information about organic wine compared to natural. This is probably due to the higher awareness of organic wine, which can be explained by the existence of a regulated certification with great visibility given that it is carried by other food products for more than 30 years. Our results are in line with previous research on the confusion between natural, biodynamic, and organic wine (Urdapilleta et al. 2021; Delmas and Lessem 2017; Sogari et al. 2016), due to the lack of a regulated natural wine certification and the uncertainty caused by the absence of a wine ingredient list (Pabst et al. 2021).

In terms of naturalness perception, our findings reveal the differences among the two countries (as noted also by Staub et al. 2020). Italians perceive natural wine as environmentally friendly and without additives, while in Spain, it is mainly considered as without added sulfites. With reference to Italy, the results confirm previous research (Galati et al. 2019; Migliore et al. 2020) showing that natural wine preferences rely on consumers’ attitudes towards the environment and health. While for Spain, the natural wine perception might be explained by the surge in greenwashing strategies by winemaking companies aimed to equate wine without added sulfites with environmentally sustainable and healthy wines (Costanigro et al. 2014; D’Amico et al. 2016). Indeed, confusion among consumers is currently fostered by several diverse natural wine claims. For instance, the Italian associations VAN, VinNature, and ViniVeri in Italy allow winemakers to add a maximum of 40, 50, and 80 mg/l of sulfites, respectively, while other natural winemakers’ associations in Europe, from the French SAINS to the Spanish AVN and alternative Italian natural wine groups, advocate that natural wines should be without added sulfites.

Additionally, the results show that different perceptions also lead to diverse motivations to drink natural wine. In Italy, natural wine consumers are mainly guided by sustainability concerns, confirming previous research (Forbes et al. 2009; Galati et al. 2019; Migliore et al. 2020), and underlining that sustainability is increasingly becoming a factor of competitive advantage (Pomarici and Vecchio 2019). While, in Spain, natural wine consumers are both guided by sustainability and hedonistic motivations, wine drinking is widely considered among Spaniards as a beverage associated with lifestyle and socio-cultural aspects, and its consumption is regarded as a hedonic experience (Williams and Atwal 2013; Alonso González and Parga-Dans 2018). Furthermore, this finding corroborates the results of Jorge et al. (2020) who recently revealed, in their wine laboratory experiment, that Spanish consumers’ preferences for organic wine are strongly related to tasty attitude, revealing that an egocentric perspective affects consumers’ decisions.

Consistent with previous evidences (Galati et al. 2019; Migliore et al. 2020; Bazzani et al. 2020), our results confirm that in both countries, a higher positive attitude towards natural products increases natural wine consumption frequency. This outcome underlines that the growing attention of consumers towards healthy eating is also affecting wine choices, as recently suggested by several scholars (Pabst et al. 2019; Bazzani et al. 2020; Pabst et al. 2021).

Current results also show that natural wine consumption is strongly related to wine consumption frequency and involvement. In both countries, the more individuals consume wine regularly, the more frequently they tend to consume natural wine. On the contrary, a higher level of involvement leads to a lower consumption frequency of natural wine. This is partially in contrast with Staub et al. (2020), who found that participants with a high level of wine involvement perceived naturalness as significantly more important than people with low involvement. However, in line with Sáenz-Navajas et al. (2016), it could be argued that the higher level of involvement leads consumers to see wine more as a hedonic beverage. This would lead their consumption choices towards extrinsic factors such as origin, terroir, grape variety, or harvest and less towards the intrinsic factors that are the focus of natural wines. In this regard, our findings indicate that lower levels of wine involvement lead to higher natural wine consumption frequency in both countries. This could be related to individuals’ search for healthier foods, which is less influenced by the product’s external cues. In the case of Italy, this particular result is also found by Migliore et al. (2020) who showed that the presence of an appellation of origin on the wine label negatively impacts WTP for natural wine.

Among the socio-demographic characteristics, the results show that younger Italian drinkers tend to consume natural wine more frequently, confirming evidences from previous researches that revealed the growing popularity of these wines especially among Millennials (Fernández 2019; Galati et al. 2019).


The current outcomes corroborate the idea that the importance of food naturalness varies across countries and cultures (Rozin et al. 2004). However, taking into consideration the natural wine, other reasons can be related to different positions adopted by particular associations across nations and the dissimilar stage of market development, which is more lively in Italy in terms of existing associations, distributors, and winemakers (Wine Intelligence 2021). Nevertheless, Spain is recently catching up and rapidly growing in terms of natural wine producers and in terms of natural wine value chain (Fernández 2019).

Our findings are subject to several limitations. First, we collected data from a convenience sample of self-selected wine consumers, which limits the potential to generalize our findings to the wine consumer populations of Italy and Spain at large. Future studies should aim to use larger, representative wine consumer samples in both countries, offering more general findings. Second, the present study, as most similar research, was based on self-reported behavior that likely suffers from social desirability bias (Fisher 1993). Furthermore, the lack of a clear and regulated definition of natural wine allows individuals to interpret its meaning in very different (and personal) manners, thus potentially leading to inconsistent measurements among respondents. The social effects of the official recognition of natural wine in France will surely bring consequences worth exploring. Finally, the pseudo-R2 values in the regression models were low, which implies that other psychological, environmental, and personal factors influence natural wine consumption frequency. Further research should try to identify other potential determinants of natural wine consumption to provide a more complete overview of consumer drivers, and could verify the existence of homogeneous consumer segments across the two countries in order to better outline the features of this new promising market segment.

  1. The French recognition of natural wine itself reflects internal debates and quarrels among natural winemakers, as it comprises two different certifications, one for wines without added sulfites and another for wines with a sulfite content of less than 30 mg/l.

  2. The selection has been performed to sort out irrelevant explanatory variables in order to improve accuracy of the effect estimates of the main interest and obtain interpretable, practically applicable models (VanderWeele and Shpitser 2011).
