i think i have to agree with joopson on the glass thickness, but i don't think it's got to do with the ior...

actually, the glass on a coca cola bottle is pretty thick. There was this picture in a physics book I saw once where they'd encased a bottle in plastic (they were demonstrating refraction). Something like a full third of the width was glass.
While encasing a bottle to check this might be out of the question for you, you could probably do a displacement test of a bottle to check the disparity in volumes (outside versus inside).

Anyways....

You can get some strange things going on when rendering glass out that can make it look thicker than it actually is (I had a similar problem with my JD glass). I think that you lighting might be to do with it as if its too bright it will refrect a lot in the glass material and make it look whiter (and thicker) that you want it

I know I had to play with the settings and the fresnel effect for the reflections quite a bit to get it looking ok for the glass, it took quite a bit of studying bottles etc to get the right look.

Looking good.
