The identification of viticulture terroir is an important issue, strongly rooted on soil science, that has major impact on vineyard management and, through marketing, on farmer income. The concept of terroir is well established but still ambiguous. Nowadays, a unique methodology to the analysis and implementation of terroirs does not exist but most of the approaches are based on a landscape classification employing multicriteria qualitative parametric models. This work departs from these empirical models and it attempts to prove that a mechanistic approach (strongly based on hydropedology) to the analysis of terroir is feasible and it enables a better use of environmental features with respect to plant requirement and wine production. More specifically, the proposed approach aims to integrate the standard terroir analysis with soil–plant–atmosphere water balance simulation modelling and GIS databases in order to ameliorate the spatial analysis of terroirs.
