This study aims to examine the formal and metric properties of Gil et al.’s (2000) scale of attitudes toward organic products, which is the most popular scale to measure these attitudes.

The sample consisted of 4,992 household shoppers living in Hong Kong, Germany, Norway, Spain and the UK. The questionnaire was distributed using a third-party consumer panel, and the fieldwork was conducted using computer-assisted Web interviewing. The approach was based on confirmatory factor analysis and measurement of invariance, as well as format analysis using a wording-syntactic and semantic descriptive method.

The scale reflects an attitude-toward-object model approach. Its use has been heavily varied (in terms of wording, item semantics and the attributes to be measured). A two-factor structure that meets the metric conditions (reliability and validity) is found. However, the analysis of invariance shows that the scale behaves differently in different countries.

This scale offers a good starting point for measuring attitudes toward organic products. However, it requires refinement to adapt to consumer evolution and improve its metric validity. Verification of its applicability in cross-national studies is recommended.

To the best of the authors’ knowledge, this is the first study that assesses the format and quantitative characteristics of this scale on a cross-national level. For scholars and companies with international interests, preventing the use of scales with poor properties at the transnational level can improve the design of future studies and save money through a more informed choice of attitudinal scale.

Este estudio examina las propiedades formales y métricas de la escala de actitudes hacia los productos orgánicos de Gil et al. (2000), que es la escala más popular para medir estas actitudes.

La muestra incluye 4.992 compradores principales en hogares de Hong Kong, Alemania, Noruega, España y el Reino Unido. El cuestionario se distribuyó utilizando un panel de consumidores, y el trabajo de campo se llevó a cabo mediante entrevistas online asistidas por ordenador. El enfoque se basó en un análisis factorial confirmatorio y en la invariancia de las medidas, así como en un análisis del formato utilizando un método descriptivo de redacción-sintáctico-semántico.

La escala refleja un enfoque de actitud basada en el objeto. Su uso ha sido muy variado (en redacción, semántica de sus redacciones y los atributos que mide). Se encuentra una estructura de dos factores que cumple con las condiciones métricas (fiabilidad y validez). Sin embargo, el análisis de invariancia muestra que la escala se comporta de manera diferente en distintos países.

Esta escala ofrece un buen punto de partida para medir las actitudes hacia los productos orgánicos, pero requiere un refinamiento para adaptarse a la evolución del consumidor y para mejorar su validez métrica. Se recomienda verificar su aplicabilidad en los estudios internacionales comparados.

Este es el primer estudio que evalúa el formato y las características cuantitativas de esta escala a nivel internacional. Para los académicos y las empresas con intereses internacionales, evitar el uso de escalas con propiedades deficientes a nivel transnacional puede mejorar el diseño de futuros estudios y ahorrar dinero a través de una elección más informada de la escala actitudinal.

This paper aims to analyze the current wine consumption situation with special attention being paid to the habits and preferences of young consumers.

The study was carried out on a sample of 318 consumers; 50 per cent of the sample were under the age of 35 and 50 per cent were older. The information gathered was then subjected to the appropriate statistical tests. The lifestyles and images of wine consumption of those surveyed was first looked at, followed by the results obtained related to consumption of drinks such as water, fruit juice, soft drinks, beer and, of course, wine.

Lifestyles are changing and the results found here indicate that the under‐35s are concerned about their health and to maintain a healthy lifestyle. This is reflected in a certain negative view of wine with its consumption being reserved for special occasions. With regard to knowledge of Denominacion de Origen, the results are pointing out that a small sector of the under‐35 group had only a vague notion of its meaning. This situation suggests a need for promotional activity by business and institutions aimed at increasing the knowledge of young people have of wine.

This study offers information to the wine industry for the improvement of young consumers' knowledge of the meaning of Denominacion de Origen as a guarantee of the origin of a product and of its quality.

The purpose of this paper is to analyse the effect of attitudes and socio-demographics on wine consumers’ real purchase behaviour for organic wine.

This study is based on GfK household panel data, a real market data source of high population coverage. A two-part fractional model was applied as two distinct categories of wine buyers were observed. The first part of the two-part fractional model consisted of a standard binary choice model and defined the likelihood of belonging to the group of organic wine buyers. The second part of the model only took organic wine buyers into account and described their purchase intensity.

Preferences for organic products and sustainability concerns (e.g. environmental and social concerns) drive organic wine purchases. Proving a causal relation between attitudes and purchase behaviour gives evidence that stated preferences are a reliable indicator to predict consumer behaviour. However, the weak relation between attitudes and behaviour confirms the existence of an attitude-behaviour gap.

Quality benefits of organic wine production need to be communicated to attract new customers. Stronger focus should be put on sustainability issues with the aim of encouraging organic customers to also increase their expenditures for organic wine.

The influence of sustainability concerns on purchase behaviour is still controversial and no study, so far, has analysed real purchase data for organic wine. The results provide new insights on why attitudes do not fully transform into purchase behaviour.

Marron growing is practiced in some regions of Western Australia where this crustacean is a native species, and offers potential opportunities to be marketed as a delicacy and also to blend with other industries, including tourism, contributing to the marketing of a region. While these opportunities exist, to date little is known about the extent to which marron growing is meaningful to local entrepreneurs in commercial terms, their level of involvement with this industry, or constraints they may face. This paper aims to examine these dimensions to illustrate marron's importance for the areas where they are grown.

A total of 26 small marron growers accepted the invitation to participate in semi‐structured face‐to‐face and telephone interviews.

Operators' comments illustrate the significant potential for marron to become both a niche market product as well as a rural niche market that helps promote the area where they are grown. However, growing marron as a full‐time activity is still very limited; in fact, many respondents grow marron marginally and as an extra income stream because of the crustacean's current high commercial value, thus suggesting the industry's current developmental stage.

With some 200 marron growers in Western Australia, the number of participating operations is limited to make generalisations of the industry.

With growing consumer sophistication, knowledge and interest in gourmet foods, the findings not only have implications for the marron growing industry, but also for hospitality and tourism, particularly in view of marron growing's potential to blend with these industries.

The study provides several insights into an unexplored area, marron growing and provides several areas for future research.

This article aims to analyse various wine differentiation strategies (price, origin, type and production system) to counteract the commercial success of new wine producers compared to traditional ones.

The methodology consisted of a survey of 400 Castilla‐La Mancha wine consumers during the month of March 2004, whose preferences were determined through several multivariate techniques.

Three consumer segments were identified: the first shops for wine mainly by price, the second, by origin and the third, by a combination of price and type of wine. In this sense, except for the first segment, where competition by a cheaper wine from other places could endanger the local market, possible strategies would be to continue emphasising origin in a traditional approach and to search for a new wine differentiation based on organic production. Both strategies, which can be carried out jointly, would require government backing in addition to support from the business sector.

This paper contributes to a greater knowledge of Spanish consumer habits by analysing the degree of influence that various factors have on attitudes towards the purchasing of wine.

This study investigates organic wine consumption and analysed the motives, preferences and basic characteristics of German consumers of organic and non-organic wines.

The comparative study is based on data from a representative survey conducted with 2,000 consumers in Germany. Two segments of wine drinkers were created according to their consumption of organic wine. Consumers of organic and non-organic wine were compared by analysing the differences in wine-related behavioural factors and socio-demographic variables.

The study reveals that consumers of organic wine differ significantly from those who do not drink organic wines. Socio-demographic factors (e.g. age and social class) and behavioural attributes (e.g. frequency of wine consumption and involvement with and preference for other organic products) demonstrate the differences between the two consumer groups.

To our knowledge, no findings exist to date regarding differences between consumers of organic wine and consumers of non-organic wine. Therefore, these results fill a research gap and provide valuable inputs both to the wine industry as well as to the scientific community dealing with organic food preferences.

This study aims to identify how Spanish consumers’ extrinsic preferences for food have evolved by examining the extant literature on food preferences in Spain, focusing on food-related attributes and food-related values.

This study is based on a synthetic review of the extant academic literature on Spanish consumer preferences for food-related attributes and food-related values from the mid-20th to the 21st century. This study uses key economic and social milestones that are most likely to influence food value chain actors to show how consumer preferences have evolved over the study period.

Spanish consumer food attribute preferences expanded as the food sector of the nation continued to grow, and value preferences showed a similar pattern from the mid-20th to the 21st century. The drivers of these preferences were trust, lifestyle, education (campaigns), sociodemographic factors and purchasing power.

Evaluating the extant literature’s contribution to consumer preferences for food-related attributes and values is important because it can aid in understanding the hierarchy and variety of consumers’ food preferences as well as the factors that drive these preferences. To the best of the authors’ knowledge, this study is the first to explore how Spanish consumer preferences evolved between the mid-20th and 21st centuries.

This paper aims to further progress in research on perceived quality of fresh fruit and vegetables. It seeks to develop and discuss two models for perceived quality of tomato, including the price variable as an indicator for perceived quality of tomato.

The data come from a survey of 400 consumers that measures the importance of a set of tomato attributes on a Likert scale. The models were adjusted by means of structural equation analysis. Two procedures were followed for model development: the first started from an exploratory factor analysis. In the second, relations and correlations among variables were established starting from the theoretical framework that differentiates among search, experience and credence attributes.

Two models of tomato perceived quality are formulated and discussed. Both established that the perceived quality of fresh tomato could be explained through nine attributes. Some of them can be deduced at the place of purchase; some, during consumption while others are a question of trust. With regard to using price as an indicator of the perceived quality of tomato, both models suggested the elimination of this variable from the model for perceived quality.

Studying perceived quality has received much attention in research on the behaviour of food consumers. Nevertheless, there are not many attempts to establish models for the perceived quality of fresh fruit and vegetables. Specifically, there are very few studies on consumer behaviour that analyse the perceived quality of tomato. Thus, this study is one of the first attempts to establish a model for perceived quality of tomato.

The purpose of this paper is to contribute to knowledge on the preferences of cheese consumers in Spain. The first step was to determine where and how frequently cheeses are purchased and consumed, along with different aspects relating to the recognition of cheeses certified by a denomination of origin (DO). The second step consisted in determining how consumer preferences are structured.

The methodology consisted of a survey of 412 consumers in the Castilla‐La Mancha Region who were buying food items for their homes. In order to process data related to the first step, a descriptive analysis was undertaken. For the second step, a conjoint analysis was carried out, with three types of attributes (price, certification and type).

The results show that cheese is a food which is present and also consumed within Spanish homes, while being bought in supermarkets at least once a week. Consumers value most the DO labels as a guarantee of quality and food safety. The cheese that is best known to consumers is the Manchego DO. Consumers prefer cheeses which are well‐priced, aged and, if possible, certified.

This paper analyses current consumer behaviour and, by means of conjoint analysis, identifies consumer preferences for cheeses in Spain. Internationally, conjoint analysis has rarely been used for cheeses, and this would appear to be the first time it has been applied in Spain.

The purpose of this study is to analyze the levels of knowledge and consumption of organic tomatoes in Spain, and their influence in consumer willingness to pay for this type of food.

The data used in this work come from a survey of 361 Spanish consumers. The paper analyzes the levels of consumption and the knowledge of organic foods, proposing a contingent valuation exercise for organic tomatoes. The Hanemann model is used to estimate the average and maximum willingness to pay for this product. A multivariate logit model was calculated, with different starting prices and variables derived from a cluster analysis of consumers.

Three distinct groups of consumers were identified, and their willingness to pay for organic tomatoes was modeled using contingent valuation. The results clearly show a generalized lack of knowledge of organic products and the confusion caused by the proliferation of labels. A clear relationship was also observed between consumers' levels of knowledge and consumption of organic foods and their willingness to pay a premium for these products. This confirms the interest shown by policy makers in promoting education and information aimed at developing the domestic market.

This paper shows an interesting approach, as research on the influence of knowledge and consumption of organic food on consumers' willingness to pay for this product is scarce, and even more if one considers the local character of many of these studies. As the premium of organic food is one of the main constraints to the growth of this sector, results may be relevant both for producers and planners.
