The rumor says that some critics may favor a producer or a consultant
is it true?

I have calculated an easy coefficient:the ratio between the average score of the incriminated wines and the average score of others wines
Of course that ratio is often favorable (ou unfavorable!), but it is usually the case this for a large majority of critics!
Results can be sorted according to the "degree of accession" of the various critics by clicking on the column header of the following tables.
