Does the order in which wine is presented make a difference? Subjects were asked to taste two different win samples in sequence, and to then indicate which wine they prefered. Both samples given to the subejcts were the same wine, although the subjects were expecting to taste two different samples of a particular variety. Of the 32 subjects in the study, 22 selected the wine presented first when presented with the two identical wine samples.
