Un Système d’Informations à Références Spatiales sur le Vignoble. Un outil performant d’aide aux recherches sur la caractérisation des terroirs viticoles


The “Terroirs d’Anjou” project led by the Agronomy sector of the Vine and Wine Research Unit of the INRA center in Angers aims to characterize the viticultural terroirs in a study area which includes 29 municipalities in the Maine et Loire and cuts across the Anjou, Coteaux du layon and Coteaux de l’Aubance appellation areas.

The research methodology on viticultural terroirs developed by UVV revolves around two main themes:
– A characterization of terroirs in the field which consists of collecting information relating to the physical components of the environment. Observations on geology, soils and landscapes thus form the basis of the study. This step is similar to a cartographic survey
– A survey conducted among winegrowers in each of the 29 municipalities. This survey is intended to integrate human factors within the study, and to study the possibilities of use as an experimental tool for highlighting the terroir effect. The questionnaire focuses on the behavior of the vine, winemaking, knowledge and empirical management of the terroirs by the winegrower.

This study therefore entails a large volume of information which must be managed in an optimal way to facilitate their processing, while preserving their particular character of localized data. Indeed, there is no direct relationship allowing to associate the data of the investigation on the one hand with those of the characterization on the other hand. The only relationship existing between these two levels of information is of the spatial superposition type. To use it and thus cross the two types of information, it is necessary to manage the associated geographical objects.

Enhancing table grape production: addressing challenges and opportunities for sustainability and quality improvement

Table grapes, being consumed as fresh, raisins, and transformed products are among the most appreciated fruits worldwide. Its popularity is increasing also due to its organoleptic and nutritional qualities that meet the consumers’ interest in healthier foods. Recent data from International Organization of Vine and Wine (OIV) revealed that table grape production has doubled in the last twenty years, and varietal availability has increased thanks to the several breeding programs.
To maintain the socio-economic impact of this sector, new challenges need to be addressed.

Methodology to assess vine cultivation suitability using climatic ranges for key physiological processes: results for three South African regions

Le climat a de fortes implications sur le bon fonctionnement physiologique de la vigne et a besoin d’être quantifié afin de déterminer l’aptitude des régions à la culture de la vigne. Une méthode, qui pourrait éventuellement servir à prévoir l’aptitude des régions à la culture de la vigne, est proposée.

Impact of the maturity and the duration of maceration on phenolic composition and sensorial quality of Divico wines

Following its approval in 2013 by Agroscope, Divico became the first interspecific grape variety in Switzerland with high resistance to downy mildew (Plasmopara viticola) and grey rot (Botrytis cinerea), and medium resistance to powdery mildew (Uncinula nectator). Extremely riche in color, Divico grapes showed great enological potential to different styles of wine. Quickly, many wine growers were interested in planting this promising variety. Many of its potential are to be explored in the coming years.
