I used one light in a large 4 x 6 soft box, behind an even larger scrim, on camera left. This produces the soft gradient lighting on the bottle. I set up a white board to reflect light into the bottle on the right side of the camera, giving it a nice line down its side. The background gradient is subtly lit with a small soft box camera right.
A simple light set up to enhance the beauty of this delicious bottle of wine.
