Coke or Pepsi?

This evening, while eating dinner here at work with a friend and co-worker, Dragan, we started talking about the differences in the tastes of Coke and Pepsi. We were both drinking Coke at the time, so I decided to go get a can of each from the pop machine and some cups....I am sure you know where this is going.

Anyway, after conducting a few blind taste tests between us and a couple other people here at work, Andre and Dave, we were met with mixed results. At times each of us were right in our guesses and at other times we were wrong. Then Dragan suggested a startling theory. He noticed that when we drank the Pepsi first, then the Coke, we could tell the difference more times than not. But when we drank the Coke before the Pepsi, they tasted more similar. We further guessed that the Coke had a stronger caramel flavor that may be sticking in our mouths and thus masking the Pepsi's flavor, making it harder to differentiate. We then tested this some more, but one person here in particular, Dave, always guessed correctly. We figure this theory works on roughly 4 out of 5 people (I rounded up since it was 3 out of 4 for us).

Test this yourself and leave comments here with your findings! By no means cancel any plans of going out dancing or shopping at the mall for this experiment...just give it a try next time the conditions are conducive for a blind taste test. Please don't cancel any doctor's appointments or vacations on account of this, unless you need a good excuse to get out of something.
