Data from the great wine taste test

A common topic of conversation among my friends, several of whom are wine snobs and several of them (myself included) is the extent to which wine quality really varies by price and general snop appeal. At a recent party at our house, Cullen Jennings decided to run an experiment in blind tasting. He bought three pairs of wine, one cheap, one expensive, and encouraged people to try to determine which was which.

Cullen Jenning's message describing the raw results, without any real analysis, is below.

Red is 1
Green is 2
Orange is 3
