Typicality related to terroir: from conceptual to perceptual representation: study of the links with enological practices

Abstract

The conceptual image of a wine related to the terroir has consequences in technical terms. Among factors affecting the typicality, producers put forward the environmental factors of the terroir system, then the variety and finally the viticultural and oenological factors. We postulate that for the production of red wine, the “phenolic maturity” must be considered as an essential criterion. The “phenolic maturity” was translated into the date of grape harvest and the duration of vatting. Because of the nature of the corresponding biochemical compounds, these choices could have important consequences on the sensory profile of wines. The objective of this study is to understand the relationship between the conceptual image of a wine and the perceptual dimension of the wine, by connecting the typicality with some technical acts. The distinctive French wine style “Anjou Village Brissac” was investigated through four methods. A survey was performed to measure the conceptual dimension, and three sensorial methods were used for the perceptual dimension (Quantitative descriptive analysis (QDA) by a sensory expert panel, Just About Right analysis (JAR) by wine experts, and assessment of the typicality by wine experts). Wine experts were producers, winemakers, and oenologists from the area. The survey allowed highlighting soil as the first factor that affects the typicality. On the other hand, the QDA and JAR profiles highlighted the prevalence of the technical factors, in particular oenological, over the environmental factors. The JAR profile allowed to classify attributes in the typicality scores. Moreover, the study made it possible to show the shift between the conceptual typicality and the perceptual typicality, from the point of view of the technical acts, but also from the sensory point of view.

Impact of pedoclimatical conditions on the precocity potential of vineyards in the canton of Geneva

Terroir studies are common nowadays but few have used precise pedoclimatic measures in order to evaluate the precocity potential. The objectives of this work were (i) to assess the effect of main terroir parameters (soil, climate and topography) influencing the phenological development of the vine, and (ii) to evaluate a geostatistic approach by using a high number of already existing plots (higher variability) to analyze the terroir parameters’ impact.

Sensory patterns observed towards the oxidation of white, rosé and sparkling wines: An exploratory study

Oxygen management is crucial in terms of wine quality. Even more for white and rosé wines, which are less protected against oxidation than reds due to the lower levels of antioxidant polyphenols. This need is due to the existence of equilibria between chemical forms depending on the redox potential.

The legal concept of “cultural heritage” to refurbish the wine sector’s priorities

Following the latest oiv global report (april 26, 2024), the prevailing perception of wine consumption finds itself undergoing one of its most challenging adjustments. It’s plausible to anticipate a shift in the scope of pdo wines towards more human-centered products (wells and stiefel, 2019), necessitating the entire sector to adapt strategies to public interest patterns (touzeau, 2010: 17-31). Previously, a dominant notion of cultural property underscored the value of wine regions; the primary interest revolved around estate owners and retailers, along with vigneron tales.

Evolution of biogenic amines content in wine during sample conservation – method optimisation for analysis of biogenicamines

The present paper reports the development of an optimized method for simultaneous analysis of
8 biogenic amines (Histamine, Methylamine, Ethylamine, Tyramine, Putrescine, Cadaverine, Phenethylamine, and Isoamylamine). It is based on a method developed by Gomez-Alonso et al. in 2007.

Untargeted LC-HRMS analysis to discover new taste-active compounds in spirits.

​For several years, the chemistry of taste has aroused high interest both from academics and industrials. Plant kingdom is a rich and reliable source of new taste-active compounds. Many sweet, bitter or sour molecules have been identified in various plants [1]. They belong to diverse chemical families and their sensory properties are strongly affected by slight structural modifications. As a consequence, the investigation of natural taste-active products in a given matrix appears as a major challenge for chemists. Such studies are particularly relevant in oenology since they allow a better understanding of wine and spirit taste.
