I've done Cal V/Nottingham comparisons and whenever a neutral fermentation is required, no one has been able to tell any difference. One guy claimed to be able to identify the Cal V batch, but he couldn't. Given three samples (two CalV), he was unable to pair them.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
