Via Robin Goldstein, the work of Coco Krumme who analyzed wine reviews and classified words according to whether they are typically used to describe expensive or inexpensive wines.

She found that “about 65% of commonly occurring words are non-overlapping.” Words like “old,” “elegant,” “intense,” “supple,” “velvety,” “smoky,” “tobacco,” and “chocolate” predict expensive wines; “pleasing,” “refreshing,” “value,” “enjoy,” “bright,” “light,” “fresh, “tropical,” “pink,” “fruity,” “good,” “clean,” “tasty,” and “juicy” predict cheap wines. As for suggested pairings, “steak” and “shellfish” predict expensive wines; “chicken” predicts cheap wines.

As Robin points out it matters whether the reviews were based on blind tastings.  If so, then the choice of word is in response to the taste of the wine and the correlation with price just tells us which words reviewers use to convey good taste.  (Assuming you think that price is correlated with taste.)  If the tastings were not blind then it is more likely that reviewers are responding to the label and are choosing words in response to the price.
