Abstract

In this paper we provide a simple and transparent non parametric methodology to express the scores of each wine expert on the same rating scale. We discuss the advantage of this methodology over a linear transformation. The non-paramatric method ensures the comparability of scores among experts and allows for a relevant average calculation of available wine scores.
