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.

Significance of factors making Riesling an iconic grape variety

Riesling is the iconic grape variety of Germany and accounts for 23% of the German viticulture acreage, which comprises 45% of the worldwide Riesling plantings. Riesling wines offer a wide array of styles from crisp sparkling wines to highly concentrated and sweet Trockenbeerenauslese or Icewines. However, its thin berry skin makes Riesling more vulnerable to detrimental environmental threats than other white wine varieties.

Winemaking techniques and wine tasting methods at the end of the Middle Ages

Les pratiques de vinification et de dégustation du vin sont souvent perçues, à travers un discours marketing très puissant, sous l’angle d’une tradition millénaire qui perdure depuis le Moyen Âge. En Bourgogne, il est courant de rattacher les racines de ces pratiques à l’activité des institutions ecclésiastiques qui possédaient d
