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

Abstract

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.

Keg wine on tap: a sustainability-oriented innovation

How could the wine industry be more sustainable? To answer this, an Interreg French-Swiss project gathered researchers to help a French keg producer and a Swiss wine distributor make their innovation more ecological, social and economical. What innovation? A reusable plastic keg with a disposable airtight pouch inside.

Effect of abiotic stress and grape variety on amino acid and polyamine composition of red grape berries

Vines are exposed to environmental conditions that cause abiotic stress on the plants (drought, nutrient and mineral deficits, salinity, etc.). Polyamines are growth regulators involved in various physiological processes, as in abiotic plant stress responses. Stressful conditions can modify grape’s composition, and in this work, we have focused on studying the effect of abiotic stress on the composition of polyamines and amino acids in grapes. In addition, the effect of grape variety on these compounds has been studied.

Using climate services to project grapevine varietal adequation under climate change – application to cv. Tempranillo in the Douro wine region

Vine growth circumstances are becoming warmer and drier because of climate change. Higher temperatures advance ripening to a point in the season less conducive to the production of fine wine, while drought reduces yields (Van Leeuwen et al., 2019). Several wine-producing regions around the world have already recognized threats to their viticultural viability (Santos et al., 2020). An economical and cost-effective strategy for adaptation is the employment of late-ripening, drought-resistant plant material (varieties, clones, and rootstocks).

Oenological potential of wines and agronomical characterisation of grapes from five white resistant Italian varieties at Serra Gaúcha, Southern Brazil

Rio grande do sul is the main grape producing state in Brazil, with the largest wine-growing area, responsible by 90% of the national production of wines and grape juices. Serra Gaúcha is the main vitivinicultural region, where around 15% of the area is destined to produce wines from vitis vinifera L. grapes. This region presents high rainfall during the grape maturation cycle, a factor that leads to great risk of attacks by fungal pathogens. the use of resistant varieties can reduce the cost and quantity of spraying, improving wine quality, focusing on a sustainable vitiviniculture.
