Agronomical assessment of a vine « terroir » map: first results in the « AOC » Minervois region

Abstract

Minervois is a vine region where the first detailed soil map was begun 30 years ago. In 2003, a new map was drawn plotting the soil-landscape associations. This map distinguishes 8 large soil units based on geology. The widest (called « marnes ») is the most complex : it is made of 57 sub-units, which leads to a high variability of the vine behaviour on this unit. We proposed a way to simplify that very complex soil information in order to understand the relationship between vines characteristics and the map sub-units of soil. The 57 first sub-units were turned into 5 new ones. Water constraint and agronomical data were examined for 2 vine cultivars on 47 vine plots among the « marnes » unit and compared to 3 of our simplified sub-units (87% of the total area of the « marnes » unit). Shoot elongation and carbon discrimination were used for estimating water regime during summer. The soil-plant water regime is revealed to be the main factor classifying the 3 sub-units : we show good relationship between grapes and vines characteristics and the new sub-units.

In 2010, the OIV adopted a resolution that defines ‘terroir’. The OIV definition understands terroir as the result of the interactions between the physical specificities of a space and human labor, with an emphasis on the subsequently produced collective knowledge (OIV-VITI 333-2010); by doing so, it alludes to the social and cultural dimensions of terroir.

Definition and planning of viticultural landscapes case study in the “Côtes du Rhône Gardoises”

Les préoccupations actuelles autour des paysages viticoles vont au-delà des clichés promotionnels développés par les stratégies marketing. En effet, les paysages sont aujourd’hui au cœur d’une demande sociale croissante qui se traduit par différentes lois (la loi paysage de 1993, le paysage reconnu comme patrimoine commun de la nation par la loi n°95-101, la création du Conseil national du paysage par arrêté du 8/12/2000).
