Colour as a driver of Pinot noir wine quality judgments: An investigation involving French and New Zealand wine professionals
2016
Despite anecdotal reports suggesting an influence of perceived wine colour on wine professionals’ judgments of wine intrinsic quality, there is a lack of empirical evidence on the phenomenon. The major aim of the present study was to investigate the importance of perceived colour as a driver of chemosensory judgments of Pinot noir wines including sensory evaluations of quality and typicality. Twenty-three French and 23 New Zealand (NZ) wine professionals judged Pinot noir wines from France and NZ on a range of attributes including perceived colour (hue, intensity, and brightness), varietal characteristics, and overall wine quality. The wines were evaluated in both standard clear glassware w…
Comparison of conventional descriptive analysis and a citation frequency-based descriptive method for odor profiling: An application to Burgundy Pino…
2010
International audience; The limitations of intensity scoring when describing the odor characteristics of a complex product have been documented in the literature. In the present work, the odor properties of 12 Burgundy Pinot noir wines were described by two independent panels performing, respectively, an intensity-based (conventional descriptive analysis) and a citation frequency-based method. Methods were compared according to three criteria: similarity of the sensory maps, control of panel performance and practical aspects. Intensity scoring and citation frequency data were analyzed, respectively, by Principal Components Analysis (PCA) and Correspondence Analysis (CA) followed by Hierarch…
Impacts du changement climatique sur la phénologie du Pinot noir en Bourgogne
2013
The viticulture is an important economic and cultural sector in Burgundy. The current climate change raises a number of issues including its impact on crops. In this thesis, the idea is to develop a methodology to address the problem: what are the potential impacts of changes in temperature on the phenology of Pinot noir in Burgundy for years 2031-2048?The evolution of temperatures in Burgundy since 1961 is characterized by a positive temperature shift at the end of the 1980s followed by a period where the temperature increases of about 1.5 ° C.One of the interests of this thesis is to develop, following a strategy developed during the thesis, a spatial database conducted over the period 19…
Wine metabolomic analysis : "chemical messages in a bottle"
2014
The main objective of this work was to develop non-targeted metabolomics analyses of bottled wines in order to decipher chemical informations from the time-related evolution of their composition. This original research was based on the hypothesis that, when analyzed, bottled wines would still hold chemical memories of envionmental parameters (vineyard management, oenological practices, climate, terroir…) at the moment of their elaboration, even after several years of ageing. A second hypothesis was that in order to anticipate the future evolution of the wine quality in terms of chemical composition, it is necessary to know what it was in the past. To that purpose, and for the first time in …
Phenological model performance to warmer conditions: application to Pinot noir in Burgundy.
2014
<p style="text-align: justify;"><strong>Aim</strong>: The current work aims to assess the performance of two phenological models - a linear model (<em>Grapevine Flowering</em> <em>Véraison</em> model, <em>GFV</em>) and a curvilinear model (<em>Wang and</em> <em>Engel</em> model, <em>WE</em>) - to warmer temperature conditions for the grapevine variety Pinot noir in Burgundy.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Simulations using historical data from the 1973-2005 period were similar between models and consistent with observations. To mimic pot…
Variabilité climatique et profils organoleptiques du Pinot noir dans le monde
2015
Wine typicity is revealed at various spatial scales, according to the variability of terroir components, which individual contribution change depending on the site. In this study, the impact of climate at global scale on the sensory profile of wine is examined.Thirty one Pinot noir wines produced in 16 winegrowing regions in Europe (Germany, France and Switzerland), North America (USA), South America (Chile) and Oceania (Australia and New Zealand) were selected. A blind testing was performed on the wines by 14 judges; among which 9 were considered sufficiently repeatable (criteria evaluated from the sensory analysis results of two identical wines). Wines were described by 26 visual, olfacto…
Perception of quality and complexity in wine and their links to varietal typicality: An investigation involving Pinot noir wine and professional tast…
2020
International audience; 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 t…
