The inability of many wine judges to achieve perfect consistency by assigning the same rating to the same wine in a blind tasting is well established. Results for four wine tastings that include blind replicates are examined in this article. Although perfection is rare, the probability distri- butions of those results show that wine judges do tend to assign closer ratings to replicates than is likely due to chance alone. Approximately one-third of judges assign ratings that are within one rank of perfect consistency, and two-thirds assign ratings within two ranks of perfect con- sistency. This finding is sensitive to judges’ capabilities, the mechanics of the tasting protocol, and the extent to which the replicate is different from other wines in the tasting. Much wine- related research to date takes judges’ individual ratings as deterministic, yet these results show that those ratings are stochastic. These results yield a probability distribution that may guide future research concerning the uses and economic implications of wine ratings.
