Photographing wine splashing out of a glass has been in vogue for a long time. Though I highly respect the skill of the photographers who make those photos and the dramatic impact of that style upon the viewer, I've never personally liked it for my own enjoyment. That's because I prefer a style that more accurately reflects the real-world ambience of pouring wine, noting that wine never splashes out of a glass without someone having to rush to clean up an unexpected, sometimes awful mess.
Even so, a rather large amount of turbulence occurs at the bottom of the glass even when wine is poured under normal circumstances with no splash outside of the glass. I wanted to accurately capture that turbulence, so I made the photo shown below. For the record, this was my 13th pour and not one of them came remotely close to splashing out of the glass.
Setup
The background, which is translucent white plexiglass, fills the frame no more and no less. A speed light is behind it facing the subject and camera. That part of the setup outlines the glass and the wine in dark tones. The short duration of the speed light stops the action of the wine being poured into the glass.
