I'm creating a scene involving a spilled Nuka-Cola bottle. Here's how it looks:
The puddle on the ground looks too.. smooth. I would like it too look a little bit more noisy and realistic. Changing color settings or roughness or IOR didn't help.

$\begingroup$ It should have some roughness (probably 0.025-0.1), IOR much more around 1 (4.9 is ridiculously high), could also use some glossy shader mixed in... $\endgroup$ – JakeD Oct 24 '16 at 14:29

From your Blender file, i've done the following node setup, if you do the same, just change a bit your camera position or lightsource position, so the fluid can have something to reflect:

On node editor, you can try the following: add glass shader --> add glossy shader--> add mix shader--> add layer weight--> connect glass and glossy to "shader" in mix shader node--> connect layer weight node's "facing" or "fresnel" to "fac" in mix shader--> connect mix shader to material output. Instead of using glass shader, you can also consider using transparent shader

1$\begingroup$ as your IOR might be too high, you might consider to use some more realistic values, like on the following post: forums.cgsociety.org/archive/index.php?t-513458.html $\endgroup$ – MCunha Oct 24 '16 at 14:15
