I don't know what sort of situation you're actually shooting in nor do I know what you have for light but...
Any time I've lit glass or a liquid, I've gotten the best results by exposing for the reflection first, then lighting the rest to fill out what you want to see. It looks like you've got a light source on each side of the glass (or at least a bounce board). Just use those light sources to get your exposure. How bright do you want those reflections? White? Just under? I'd keep 'em fairly bright but try to keep some detail.
Then, light the background without changing the rest of the light. Keep the background "white" darker than the "white" of the reflection and the glass will jump off the background. Varying the brightness of the background will, in turn, vary the brightness of the liquid. The reflective foil is a great idea if you want to alter the ratio between the background brightness and the apparent brightness of the liquid.
Good luck out there, spook.
