Perhaps. It could have to do with you knowing exactly what you are consuming as well. The only true way to test a palate is blindly. Everyone is prejudiced regarding preference.
agreed. a blind taste test of the two items lets say 5 times(as you said once there is a 50/50 chance), and if you get it right 5 times in a row you know your stuff. however, I am not currently inclined to drive out of state to buy some 5.0 or 6.0 to take the challenge. but it does sound like it would be a fun test.....
is kansas 5.0? I can ask my brothers wife to bring some coors next time she drives down(she is finishing up her internship up there, and drives back and forth).
