RT Journal Article T1 Wine ratings: seeking a consensus among tasters via normalization, approval and aggregation A1 Gergaud, Olivier A1 Ginsburgh, Victor A1 Moreno-Ternero, Juan D. K1 Wines K1 Ratings K1 Global Wine Score K1 2018 en-primeur Bordeaux wines K1 Judgement of Paris AB The modern era of wine journalism has provided abundant information about wines and widespread use of numerical rating systems. A tiny difference, especially at the top of the distribution of ratings, may have striking consequences on wine sales and investment returns. This article provides a general framework to obtain a consensus among tasters’ opinions (reflected as numerical wine ratings) via three subsequent stages: normalization, approval, and aggregation. It is inspired by contributions in political science, social choice, game theory, and operations research. We apply it to the Judgment of Paris as well as to rank 2018 en-primeur Bordeaux wines, rated by five international experts. (JEL Classifications: C18, L15, L66).
