This paper aims to consolidate the state of academic research in the field of appellations of origin for agri-food products. The methodological option was to elaborate a literature review. Analysis was made of 80 articles on Scopus and Ebsco databases, covering publications since 1992. The results of the review allowed identification of four main clusters: “Geographical Indications”, “Designation of origin”, “Consumers’ and producers’ perspective”, “Typical and traditional food” and a few others secondary clusters. Suggestions for future research are pointed out in the conclusion.
