This article focuses on the food heritage processes of a Tuscan traditional product: the zolfino bean. Categories of heritage and authenticity are here defined, the former as the space for activating top-down politics and the latter as the tool legitimizing the heritage actors in the construction of the product’s plus value—experts, institutions, and local networks. The zolfino heritage process triggers a conflictual and strategic re-writing of community history, where the parameter of authenticity defines the borders of production according to the varying interests involved.
