It looks like you've worked on doing a selective colour image - hard to tell though. If so, what was your workflow for that effect?
It may look like that, but no - the shot was taken against a black background with a flash and a torch. The torch was behind and well below the glass with a hand made snoot to limit the beam spread (thus giving the splash of colour from the red wine) and the flash was hand held on the same level as the glass, but in front and to the left.
