Unlike most of my photos of wine, I had no reason to make this one other than that I like the concept. The middle glass has dessert wine in it. Such a small glass is often used because dessert wine is so often enjoyed in relatively small portions.
Setup
The background is translucent vellum. A small continuous-light lamp behind the background is shining toward the subject and camera. That lighting displays the outline of the transparent glass and translucent wine in dark tones. The vignette is created solely by the lighting setup.
