This pragmatic study addresses the question of the plural realities that emerge from perception, based on an empirical analysis of the tasting activity of wine amateurs and olfactory experts. Though they share the same requirement of rooting taste in the product under scrutiny, they also significantly differ regarding the constraints with which their tasting results have to comply: repeatability for experts’ tasting results, and activity contiunuation for amateurs. Both therefore foster the emergence of two contrasting realities: a stabilized one for (...) experts; an ‘un-stabilized’ one for amateurs. Both happen to fit with the ‘fiction’ and the ‘reference’ modes of existence of Latour’s inventory, which extends and relaunches the analysis of the coexistence of activities initiated by the works on ‘boundary objects’ some decades ago. Finally, the notion of taste is reinterpreted as a translation operator between tasting realities. (shrink)

The sociology of science has shown that the scientific quest for truth, framed by the search for objectivity was granting objects of knowledge the form of independent and autonomous things, “data” already given and preexisting their observation. But do “real” objects only fit the form of data or things? If not, to which other form and objectivity do they fit? The author considers the question by examining the dispute between scientists and vintners on the issue of terroir, a complex combination (...) of viticulture and wine-making practices and agro-climactic factors, which gives wines a particular taste, or terroir typicity. For scientists who are unable to reduce it to a stable list of determining factors, terroir is an unfounded notion, an imaginary social construction, and an economic barrier. Producers, on the other hand, along with the wider distribution network of terroir wines, consider terroir as a real object, although one whose manifestations cannot be evaluated using the same procedures as those of scientists. By analyzing how proof of terroir is implemented, the author uncovers a regime of existence of objects different from the scientific regime: a pluralist one governed by critical discussion from which objects emerge as distributed results of a production process.
