Relationship between soil and grapevine variety in the wineyard of Jura: example for the “Trousseau” variety from the “Terroir” of Montigny-Lès-Arsures (France)

Abstract

Seven plots located in the commune of Montigny-lès-Arsures (Jura, 39), planted with grapevine varieties Trousseau and Savagnin, were chosen for a study of soil pits and a distribution of major and trace chemical elements in soils and wines. It was shown that the mineral matrix of the soil reflects the geological substratum and the sub-surface alteration process, while the organic soil matrix depends on agro-viticultural practices. Major and trace elements (54 elements analysed) were assessed in the surface soil layer (Ap horizon) and in two sub-soil layers (B or C horizon). Major elements reflect the influence of the limestone-marl substratum (Trias-Lias), sometimes dominated by silico-aluminium constituents (clay particles inherited from the altered Bajocien layer). For trace elements, a principle Component Analyses (PCA) shows a distribution of the plots in three groups, which are defined by their pedological – sedimentary origin: soils on Clay with “Chailles”, soils on Trias and Lias marls, and soils on clay and alluvial fan from Bajocien sediment. Patterns of chemical element among soil layers show the contribution of the natural geological background and of the agro-viticultural practices. In the soil surface layers of some plots, high levels of trace elements (Pb, Cu and As) are the result of the use of pesticides. The Principal Component Analyses of major and trace elements in wines do not show a distribution of the plots based on pedological or sedimentary origin, but based on production factors, in this case the vine grower. This conclusion is justified by the geochemical homogeneity (same sedimentary origin, same rock type) of the geological origins in the area that was studied.

Montpellier vine & wine sciences (M-WineS)

The Occitanie Region is the first vine-growing area in France: 270 000 hectares of vineyard and an annual production of 15 million hectoliters. Its annual income reaches 1 900 million euros, of which 900 million euros in export.The vine and wine sector is facing many issues: inputs reduction, adaptation to climate change, maintaining the production competitiveness, digital tools integration in production and transformation processes, and the production of quality wines meeting the consumer demand.

A methyl salicylate glycoside mapping of monovarietal Italian white wines.

Among the main plant secondary metabolites, glycosides have a key-role in wine chemistry. Glycosides are non-volatile complex composed of a non-sugar component (aglycone) bound to one or more carbohydrates.

Chemical boundaries of wine identity: rationalizing grape and wine aroma diversity for improved terroir management

Aims: Wine perceived quality lies on a number of different factors. Among these, sensory features, which are in turn dependent on chemical composition, play a primary role. There is traditionally a great emphasis on producing wines that have specific sensory profiles, particularly aroma, that reflect identity features connected to the place and the variety of origin. In the case of high quality

Gas chromatography-olfactometry characterization of corvina and corvinone young and aged wines

AIM AND METHODS: Corvina and Corvinone are the two main grape varieties used in the production of Valpolicella, Recioto and Amarone, top-quality red wines in north-eastern Italy. This work aimed at determining the aroma composition of Corvina and Corvinone experimental wines and identify the main aroma compounds contributing to the aroma characteristics of Corvina and Corvinone monovarietal wines. Five Corvina and five Corvinone wines were studied, the grapes coming from five different vineyards in Valpolicella. Volatile compounds were extracted by SPE and identified and quantified by gas chromatography-mass spectrometry (GC-MS), whereas their aroma impact was determined by gas chromatography- olfactometry (GC-O).RESULTS: Based on the GC-MS-O analysis, 95 odor zones were detected, from which 68 compounds were successfully identified. Using the criterion of a value higher than 30% in modified frequency (MF %), 51 compounds were selected and grouped according to odor similarity. Compounds with values below 30% were discarded.
