The use of soil electrical resistivity to monitor plant and soil water relationships in vineyards
2015
Abstract. Soil water availability deeply affects plant physiology. In viticulture it is considered as a major contributor to the "terroir" expression. The assessment of soil water in field conditions is a difficult task especially over large surfaces. New techniques, are therefore required to better explore variations of soil water content in space and time with low disturbance and with great precision. Electrical Resistivity Tomography (ERT) meets these requirements, for applications in plant sciences, agriculture and ecology. In this paper, possible techniques to develop models that allow the use of ERT to spatialise soil water available to plants are reviewed. An application of soil wate…
Soil Erosion as an Environmental Concern in Vineyards. The Case Study of Celler del Roure, Eastern Spain, by Means of Rainfall Simulation Experiments
2018
Soil erosion in vineyards is considered as an environmental concern as it depletes soil fertility and causes damage in the fields and downstream. High soil and water losses decrease soil quality, and subsequently, this can reduce the quality of the grapes and wine. However, in specialized journals of viticulture and enology, soil erosion studies are not present. This paper surveys the soil erosion losses in the vineyards of Celler del Roure, Eastern Spain, as an example of Mediterranean vineyards. We applied rainfall simulation experiments (10 plots) using a small portable rainfall simulator and 55 mm h−1 in one hour to characterize soil erodibility, runoff discharge, and soil erosion…
Wine Yeast Terroir: Separating the Wheat from the Chaff-for an Open Debate.
2020
Wine terroir is characterized by a specific taste and style influenced by the cultivar of the fermented grapes, geographical factors such as the vineyard, mesoclimate, topoclimate, and microclimate, soil geology and pedology, and the agronomic approach used. These characteristics together define the concept of “terroir”. Thus, regional distinctive flavors in wine have been the subject of many studies aimed at better understanding the link between the wine and the vineyard. Indeed, the identification of key environmental elements involved in the regional variation of grape and wine quality characteristics is a critical feature for improving wine production in terms of consumer preference and…
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…

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 Route des Vins et l’émergence d’un tourisme viticole en Bourgogne dans l’entre-deux-guerres
2014
À la fin du XIXe siècle, les guides excluent totalement la gastronomie et la vigne des visites qu’ils proposent aux touristes de passage en Bourgogne. Seuls les sites naturels et les monuments historiques attirent l’attention des voyageurs. La gastronomie et le vin sont alors perçus et vendus comme des produits de luxe aristocratiques et internationaux – c’est-à-dire territorialement désincarnés. Le poids du négoce et sa liberté en termes de vinification (capacité d’assemblages de vins d’origines géographiques différentes) conditionnent amplement cette réalité. À la fin des années 1930, la transformation des normes de production et de commercialisation des vins en faveur d’un système d’appe…
Le prove di vinificazione della cultivar grillo su tre vigneti sperimentali site nel sottobacino Iudeo - Bucari (TP).
2014
Gli Autori, dopo aver descrittole caratteristiche ambientali del sottobacino Iudeo Bucari e l’attività agricola prevalentemente legataalla vitivinicoltura, descrivono alcune prove di vinificazione di uve Grillo provenienti da tre vignesite nel sottobacino Iudeo – Bucari gestite in modo ordinario, delle quali si è monitorata la maturazione delle uve. L'obiettivo è quello di caratterizzare il prodotto vino ottenuto attraverso una tecnica di vinificazione uniforme ed ordinaria nella zona, ma che mira a mettere in evidenza la diversa qualità tecnologica delle uve utilizzate espressione dicontesti eco-pedologici diversi.
