In part 1 of “Blind Wine,” we introduced our blind wine-tasting experimental setup, which included some survey questions asked ahead of time of each participant. In part 2 we looked at the results of that survey. Here we’ll examine how well the survey results align with the experimental results.

Our first two participants, Danielle and Sheryl, enter the conference room and are given blindfolds as we explain how the experiment will proceed. As we administer the tasting, the colors of the wine are obvious, but we don’t know the true types, which have been masked as A, B, C, and D.

As Danielle and Sheryl proceed through each tasting, it’s easy to note that they start off correctly identifying the color of each wine; it is also obvious that tasting methods differ greatly from person to person: Danielle tends to take one or two sips, whereas Sheryl is drinking the entire sample.
