«Observatoire Mourvèdre»: (2) climatic mapping for successful plantation of Cv. Mourvèdre

Abstract

A statistical model of sugar potential for Mourvèdre grapevine cultivar has been obtained using a group of 32 plots all around de south-east french mediterranean area. It is aimed to better understand the relations between viticultural practices and quality. The model shows strong influence of the temperature components on maturity. That is why a mapping valorization has been worked on at the local scale of a small viticultural region (2000 ha) and for the year 2005. The interpolation of temperature data was possible thanks to the MITEF method, which is acurate at a resolution of 50m. Rebuilding phenological stages has been done with a model using temperature summing adapted to Mourvèdre cv.. With moderate level of yield and canopy, the sugar potential for 2005 ranged from 11 to 14 %vol. depending on the location. With a maturity level of 12% vol. given as a minimal, it is thus possible to determine favourable and less favourable areas for the variety. Finally, turning up or down the level of yield or canopy gives us simulations of the impact of the grower practices on maturity potential, leading to an extent or a reduction of the possible planting area.

Quelles cibles moléculaires pourraient expliquer l’effet du terroir sur la composition des baies en sucres et acides?

Le manque de connaissances concernant la physiologie de la maturation du raisin a longtemps interdit d’interpréter l’effet du terroir ou du millésime sur la qualité des vendanges en termes moléculaires. L’hypothèse selon laquelle c’est la perméabilité membranaire qui contrôlerait le sens comme l’intensité du stockage des acides est pourtant déjà ancienne (1). L’étude du transport des acides organiques et de son coût énergétique permet d’avancer certaines hypothèses concemant les sites potentiels de la régulation du contenu en sucres et acides du raisin sous l’effet de paramètres environnementaux.

For a phenomenology of terroir. A consumers’ perspective

This study investigates the notion of terroir by applying a phenomenological approach, focusing on the subjective experience of consumers. We will consider how terroir is described by consumers in order to gauge their subjective viewpoint and understand their way of describing and defining this spatiality.
