Sensory and chemical drivers of wine minerality aroma: An application to Chablis wines
2017
The goal of this work was to evaluate the effect of vineyard position on the minerality of wines and to establish relationships between minerality scores, sensory descriptors and chemical composition. Sensory analyses included minerality rating and free description performed by wine professionals under two conditions: orthonasal olfaction alone and global tasting. Chemical characterization included analysis of major and minor volatile compounds, volatile sulphur compounds, mercaptans, metals, anions and cations. Results showed a significant effect of the river bank on wine minerality scores only in the orthonasal olfaction condition, samples from the left being more mineral than those from …
The Development and Promotion of Controlled Designations of Origin (Appellations d’Origine Contrôlées) in Burgundy: The Recognition of Terroir Wines …
2019
From the end of the nineteenth century to the first half of the twentieth century, French, and especially Burgundian vineyards will undergo profound changes with a relatively important transformation of wine production and marketing standards. Indeed, in the nineteenth century, the wine merchants are dominating the wine production in Burgundy. They buy grapes, make wines, breed and sell all the wines put on the market. However, thanks to economic and political changes affecting the sector during the last third of the nineteenth century (phylloxera crisis, overproduction, fraud, Third Republic,..), a political, legal and commercial fight led by winegrowers trade unions begins. They stick to …
A grape and wine chemodiversity comparison of different appellations in Burgundy: vintage vs terroir effects.
2013
Abstract This study aimed at assessing the ability of high resolution Fourier Transform Ion Cyclotron Resonance – Mass Spectrometry (FTICR–MS) to differentiate grapes and corresponding wines from distinct vineyards managed by a same producer, according to complex chemical fingerprints. Grape extracts (at harvest) and corresponding wines from four different vineyards, sampled immediately after the alcoholic fermentation over three successive vintages, were analysed by FTICR–MS. Thousands of metabolites that are specific to a given vintage, or a given class (wine, skin or must) could be revealed, thus emphasising a strong vintage effect. The same wines were reanalyzed after a few years in bot…

Les terroirs viticoles : une méthodologie de zonage en fonction du sol
2010
Terroir is a key-concept in viticulture that is more and more widely recognized to explain variations in wine quality and wine style. Terroir refers to an area and thus possesses a geographical dimension. Hence, zoning of viticultural terroir is necessary. This paper addresses soil related aspects of terroir zoning. The first step of the zoning process is a clear identification of the objectives that are being pursued: demarcation of production areas, the adaptation of the viticultural management practices to variations in soil types or the protection of viticultural landscapes. The second step is the definition of a scale adapted to the objectives. The precision of the zoning increases wit…
Evolution et transformation des sols viticoles en lien avec l’évolution et la dynamique des paysages et parcellaires viticoles
2018
International audience; Les sols et les paysages évo- luent conjointement sous l’effet combiné de facteurs naturels et humains. Cette coévolution se retrouve dans l’analyse des terroirs viticoles, construits et transformés au cours du temps. Ainsi les sols viticoles obser- vés aujourd’hui sont l’héritage d’une construction multiphasée et d’occupations successives qui ont transformé progressi- vement les paysages viticoles. Aussi, la compréhension des sols ne peut être dissociée de celle de la structuration du pay- sage, à un tel point que des dif- férences entre terroirs peuvent s’expliquer, entre autres, par des trajectoires agraires différentes. Les paysages viticoles sont des mosaïques d…
