Abstract: Wine consumers and producers make decisions partly on ratings of wine critics. Research into reliability (correspondence of repeated ratings of the same wines by one critic) and consensus (correspondence of ratings between critics or competitions) have yielded low estimates. However, Ashton (2013), looking at the consensus among only prominent critics of red Bordeaux, vintages 2004–2010, found a correlation of around 0.60. Here, I revisit these data, and extend the analyses to the years 2011–2016 for the same wines, but with additional new critics. Agreement among the critics (r = 0.57) of these new years is comparable to those found by Ashton (r = 0.60), with a slight upward trend. Overall, critics agree more about what they do not like. Regarding prices and ratings, wines score below-average ratings when they cost less than 35 euro, and higher ratings between 35 and 100 euro. In wines more than 100 euro there is no correlation between ratings and price. (JEL Classification: C99)
