his work began as an intellectual game, in order to discuss the notion of wine quality in terms of terroir and territory spatial structure. Vine and wine quality has long been questioned by scientists. Each discipline approaching it with his own tools. One of Frenchs geographers who mark the discipline history was Roger Dion (1896-1981) whit an historical approach of spatial vineyard structuration. In this work we have revisited the seminal paper of Roger Dion (1952) on viticole geography whit a new kind of tools. Indeed to assess this fundamental study, we have used distributed computational modelling based on Agents based Model (ABM). This paper is the opportunity to discuss the origin of the wine quality, and how it evolves over time by considering various factor formalized by R.Dion and other resulting from the modelling approach.
