One can get pretty close to the coca-cola formula using chemical analysis. i think it would be a good documentary show to do this in CSI miami style, and i bet funding wouldn't be that hard to get :)
Also, I have no real way to confirm, but I've heard (via friend of a friend: suspicion +10) quite a big part of a high-value flavour science is not just now it tastes, but that it is hard to reproduce faithfully, by means of unnecessary extra additives, novel process control requirements, and unusual synergistic effects.
