Le vignoble gallo-romain de Gevrey-Chambertin "Au-dessus de Bergis", Côte d'Or (Ier-IIe s. ap. J.-C.) : Modes de plantation et de conduite de vignes …
2011
Recent excavations at " Au-dessus de Bergis " in Gevrey-Chambertin (Burgundy, France) brought to light in 2008 and 2009 numerous, rectangular aligned pits interpreted as an ancient vineyard dated from the mid-first, mid-second century to the third century AD. The vineyard measured at least one hectare in area and was bounded to the south by a hedge or fence. It was composed of parallel rows oriented 6° N that may have been trained over and along high, inclined wooden frames. Vine stocks were renewed by layering, over several generations of plants. This vineyard attests to the spreading of vineyards from the mid-first century AD, as was initially supposed, and it documents some agricultural …
Study of the polysemic term of minerality in wine: Segmentation of consumers based on their textual responses to an open-ended survey
2016
International audience; Over the past 20 years, the word "minerality" has been increasingly used in the description of wines. However, a precise definition of the concept of minerality appears to be inexistent, and no consensual meaning, even among wine professionals, can be identified. Although this word usage seems to spread out from wine professionals to consumers, research on what consumers assume about minerality is scarce. This paper aims to study the various concepts about minerality held-by consumers by using an open-ended questionnaire.A total of 1697 French-speaking consumers responded to an, online survey and their free answers were analysed using statistical textual methods. The…
La risposta produttiva di alcuni vitigni nel sottobacino Iudeo - Bucari (TP).
2014
Gli Autori dopo aver descritto le caratteristiche ambientali del sottobacino Iudeo Bucari e l’attività agricola prettamente legata alla vitivinicoltura, soffermano l’attenzione sulle potenzialità produttiva di questo territorio espressa da diversi vitigni. L'obiettivo è quello di trasferire su di una basecartografica il diverso comportamento produttivo dei vitigni più rappresentati nel sottobacino Iudeo - Bucari, con il fine ultimo di fornire un valido strumento agli agronomi liberi professionisti ed ai tecnici delle cantine al fine di indirizzare l’attività produttiva dei viticoltori e migliorare la gestione dei suoli del territorio.
NMR spectroscopy evaluation of direct relationship between soils and molecular composition of red wines from Aglanico grapes
2010
1H NMR spectroscopy was employed to investigate the molecular quality of Aglianico red wines from the Campania region of Italy. The wines were obtained from three different Aglianico vineyards characterized by different microclimatic and pedological properties. In order to reach an objective evaluation of “terroir” influence on wine quality, grapes were subjected to the same winemaking procedures. The careful subtraction of water and ethanol signals from NMR spectra allowed to statistically recognize the metabolites to be employed in multivariate statistical methods: Principal Component Analysis (PCA), Discriminant Analysis (DA) and Hierarchical Clustering Analysis (HCA). The three wines we…
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…
Impacts interculturels au Néolithique moyen. Du terroir au territoire : sociétés et espaces.
2006
International audience; INTERACTIONS CULTURELLES ET EMPRISE DES SOCIÉTÉS NÉOLITHIQUES SUR LES ESPACES"Interactions culturelles", "espaces", voilà bien des sujets que certains pourraient qualifier de rebattus ! Diverses éditions antérieures du colloque néolithique n'ont-elles pas fait de l'un ou l'autre leur thème central ? Leur choix, pour ce colloque ne relèverait-il alors que d'une soumission aux vogues du moment ? On privilégie en effet volontiers ces derniers temps les débats touchant aux relations interculturelles. Et il paraît de bon ton de sacrifier aux approches spatiales, quand ce n'est pas à leur seul instrument, le "SIG". Mais, au delà de ces considérations un peu simplistes, ce …
1H NMR-Based Metabolomics to Assess the Impact of Soil Type on the Chemical Composition of Nero d’Avola Red Wines
2023
: In this study, the soil effect on the micro-component composition of Nero d'Avola wines obtained from different locations was investigated through 1H NMR-based metabolomics. Two different approaches were applied: the targeted (TA) and the non-targeted one (NTA). The former differentiated the wines by profiling (i.e., by identifying and quantifying) a number of different metabolites. The latter provided wine fingerprinting by processing the entire spectra with multivariate statistical analysis. NTA also allowed investigation of the hydrogen bond network inside wines via the analysis of 1H NMR chemical shift dispersions. Results showed that the differences among wines were due not only to t…
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…
La revendication d'un terroir viticole : la Côte-de-Beaune à la fin du XVIIIe siècle
2011
International audience; L'habitude d'associer précisément le vin à son lieu de production, à son « climat », opération définissant à l'heure actuelle le terroir viticole bourguignon, apparut au cours du xviii e siècle. L'histoire de la règlementation commerciale du « vin de Beaune » depuis le Moyen Âge laisse entrevoir quelques raisons profondes de ce processus essentiel de formalisation d'un terroir, lequel traduit l'évolution des contraintes socio-économiques, entre droits collectifs et libéralisation du commerce. Le lieu en effet, inutile aux yeux des législateurs dans la définition du vin tant que les modalités de règlements purent se limiter au cadre strict dessiné par les privilèges d…
