The background is a piece of stain glass I have for my "other hobby". The "reflective" surface under the bottle is the shiny side of poster board.
I used a desk lamp behind the glass background and I'm holding a LED lamp set to blue directly in front of the bottle trying to center the reflection on the glass background.
