Extension to the Saumurois-Touraine area of an Anjou-originated method for the characterisation of the viticultural terroirs. (Loire Valley, France)

Abstract

[English version below]

En Anjou, une méthode de caractérisation des terroirs viticoles a été développée. Elle utilise un modèle de terrain basé sur la profondeur de sol et son degré d’argilisation. Le modèle concerne des terrains issus principalement de roches mères métamorphiques et éruptives du Massif Armoricain. Cet outil de caractérisation des terroirs viticoles nécessite d’être adapté lorsqu’il s’agit d’ensembles géologiques très différents, en particulier sur sols d’apport et de roches mères tendres et poreuses du Bassin Parisien. Une meilleure compréhension de la réserve hydrique des sols apparaît être un critère important de l’interaction entre le milieu et la plante. Afin de mener à bien cette expérimentation, un réseau de parcelles d’étude a été mis en place sur cinq appellations d’origine contrôlée de la moyenne Vallée de la Loire.

In Anjou, a method for the characterisation of the viticultural terroirs has been developed. It uses a terrain model based on the depth of the soil and its clay content. The model applies to soils derived from metamorphic and igneous bed-rocks belonging to the Armorican Range. This tool for terroir characterisation needs to be adapted to different geologic systems, in particular to soils resting on soft and porous sedimentary bed-rocks belonging to the Parisian Basin. A better understanding of the water supply regime seems to be an important criteria of the interaction between the environment and the vine. To achieve this goal, a multisite network was established on five Appellations of Controlled Origin (A.O.C.) in the Mid-Loire valley.

Perceptive interactions and wine typical fruity aroma 

In this study we developed a methodology to prepare aromatic reconstitutions from fractions of a wine organic extract and we assessed these reconstitutions both in wine model solution and in de- aromatized wine.

What defines the aging signature of Chasselas wines?

Chasselas is a refined grape variety renowned for its subtlety and its remarkable ability to reflect terroir characteristics [1]. Typically consumed young, it is appreciated for its low acidity and delicate fruity and floral aromas.

FOURIER TRANSFORM INFRARED SPECTROSCOPY IN MONITORING THE WINE PRODUCTION

The complexity of the wine matrix makes the monitoring of the winemaking process crucial. Fourier Transform Infrared Spectroscopy (FTIR) along with chemometrics is considered an effective analytical tool combining good accuracy, robustness, high sample throughput, and “green character”. Portable and non-portable FTIR devices are already used by the wine industry for routine analysis. However, the analytical calibrations need to be enriched, and some others are still waiting to be thoroughly developed.

Correlation between stable isotopic composition of the fungus aspergillus niger and its growth substrate and the extracted chitin

Wine is one of the most consumed and appreciated beverages in the world. Due to the growing attention paid to consumer health, there is a continuous search for sustainable alternatives to common additives (such as sulfur dioxide) used to preserve wine. An example is represented by chitosan, the main derivative of chitin, approved for the treatment of must and wine since 2009 by the “international organization of vine and wine” (OIV/OENO 338a/2009) and by the european commission (EC Reg. No. 606/2009).
