comment Solar stills with Wine
@KyleKanos I'm not trying to make alcohol obviously... If I were, I wouldn't be using a solar still. I just happen to be interested in solutions of alcohol and water. Even if I were interested only in that, the question is related absolutely to intermolecular forces, condensation, and evaporation. What I'm asking for is a treatment as in physics, not how a sommelier would analyze it or something. I hope I could persuade people to stop interpreting my question this way.

comment Solar stills with Wine
How does the concentration (of alcohol) of the distillate vary with time? I would expect it to rise to a peak, then fall to the original concentration as the water also get condensed into distillate. Can you give an approximation for this variation?

@Danu There, changed it. I don't know why, I just assumed the OP was correct.

comment Why 'max' in $hf=\phi+{1\over{2}}mv_\text{max}^2$?
@spraff Yes, basically.
