That's moving very fast and the markers disappear, I would mask out the bottle and do a 3D model instead. Add blur and motion blur, color correct etc and call it a day.

Word. I might almost replace the entire scene and just use the original as a reference. But yeah, CG bottle is what most peoples would do.

There really are no need at all to replace the bottle though you easily could. For a shot like this, so short, I'd propose you'd just match it by hand. As I'm in Nuke already today (christmas was yesterday here in Sweden), I set this proof of concept up in 20 minutes - just google'd a beer label, slapped it on a cylinder, used the same cylinder as an emitter for some Nuke particles using a sphere for the droplets, somewhat matched the camera, did some fine tuning with a grid warp, some basic CC and rendered it out... :)

Or direct fullscreen link:

Oh, and I had to loop the clip a couple of times as Youtube really doesn't handle sub second long clips well. :)
