Evaluating consumers' sustainable choice of wine: A store experiment
2013
Poster (1 page) ; http://www.pangborn2013.com/; International audience; In order to develop successful environmentally sustainable policies that help consumers to change their consumption patterns, it is necessary to better understand consumers' choice criteria and the potential impact of an information campaign. As hypothetical methods are often criticized and as Smith (1980) and Lewitt and List (2007) have shown that laboratory behavior is a good indicator of actual behavior, an experiment was conducted in an experimental store. This option makes possible to control the range of proposed wines and their prices and thus to study the impact of production process, price on purchase and to ev…

Difference testing: Methods and appropriate use
2010
National audience; Difference tests are some of the most common methods employed in sensory evaluation of food and beverages. The objective of difference tests is basically to determine whether a difference exists between two products. There are many different types of test, such as the duo-trio test, the triangle test, the same-different test and the A-not A test. These tests, with their strengths and weaknesses, will be presented briefly during the talk. Whatever the test employed, some basic principles must be respected, e.g. sample coding with three digit numbers, and sample presentation in a balanced order. In some instances the tests must be restricted to one sensory modality. In such…
Evaluating consumers' willingness to buy environmentally friendly wines: A store experiment
2014
poster + communication courte confidentiels; The French program Ecophyto 2018 aims at achieving a 50% reduction in pesticide use by 2018. The vine-growing sector being the second largest user of pesticides in France, there is a strong need for French vine-growers to engage in more environmentally sustainable practices. However, they will do so if they are sure that consumers are ready to buy environmentally friendly wines. Thus, the two main objectives of this study were to identify consumers' willingness to buy environmentally friendly wines and to estimate the impact of an information campaign. 220 wine consumers participated in the study. Each consumer came twice, at a 3-week interval, i…
Descriptive methods based on citation frequency
2010
International audience; The limitations of intensity scoring when describing the odor characteristics of a complex product have been documented in the literature. Wine is indeed aromatically complex. This presentation aims to present another descriptive approach based merely on the presence/absence of odorant notes in wines. To test the interest of this method, we carried out the sensory description of odor for 12 Burgundy Pinot Noir wines by two independent panels, one with an intensity-based method (conventional descriptive analysis, DA) and the other with a citation frequency-based method. Three criteria were compared: similarity of the sensory maps, control of panel performance and prac…
Minéralité du Chasselas: une notion sensorielle partagée par les professionnels?
2015
Le projet «Minéralité des vins : étude et valorisation d’un concept en vogue mais méconnu» a été sélectionné dans le cadre du programme de coopération territoriale européenne Interreg IV A France-Suisse 2007–2013.; Les commentaires de dégustation utilisent de plus en plus la notion de minéralité pour décrire les vins. Toutefois, la définitionde ce facteur n’est pas fixée et s’appuie souvent sur des descripteurs sensoriels divers. Cet article vise à savoir si, au-delà de la définition, les professionnels arrivent à accorder leur perception sensorielle de la minéralité. 62 professionnels suisses et 19 professionnels bourguignons ont noté le niveau d’exemplarité de la minéralité de 80 Chassela…

Interaction between armenian-clay-based ceramics and model wines
2022
The use of ceramics for the transformation or conservation of wine has existed since the origins of wine, but the impact of ceramics on wine has not received much attention.However, in contact with the wine, ceramics are generally not neutral materials and the constituent minerals of ceramics are led to dissolve. This work mainly aims to study the migration of elements from ceramics to wine.To our knowledge, this question has so not been addressed so far, at least with our chosen approach.This study required the prior characterization of the materials and the ceramics produced in the laboratory.The analyzes (XRF, XRD, and SEM/EDX) revealed that the natural material used for the manufacture …
