Grapevine responses to terroir: a global approach

Abstract

This paper deals with the technical and/or practical treatment of terroir as a study concept, together with related functional aspects. Functioning of the terroir relies on the relation between climate, soil and vine. In addition to this interaction, a comprehensive study concept for terroir requires the consideration of viticultural and enological sciences and techniques necessary to ensure the assurance of wine quality, together with spatial aspects of the grapevine response to environmental factors, as required for vineyard management. In order to comprehend the quality of the harvest, it is necessary to understand the relationship « whole plant - berry ». An easy field and laboratory method to study the relationship between the whole plant and berry and the consequences thereof for wine quality is proposed. Knowledge of grapevine water status and the biochemical evolution within the grape berry from berry set onwards are important issues for the understanding of the role that terroir plays with respect to the quality of the harvest and the wine style or « typicality ».
