I realize this was asked before, but I´m looking for a more specific answer. There seem to be 2 answers to this question, which is correct? I would intuitively say that the beer would freeze as a mixture (at a lower temp as well). This is along the same lines as adding salt to water to lower the freezing point. However, Ice Beer is produced by freezing the beer, then separating the water crystals (which also contain insoluble polyphenols and proteins among other compounds which in turn all leads to a smoother, stronger beer.) It seems that the production of Ice Beer does not agree with the laws of chemistry/physics....To clarify my question, why during Ice beer production, does the alcohol not freeze with the water?? I realize that the freezing point of pure alcohol is -117.3 degrees C, but in a dilute solution (such as beer, I would think it would freeze as a solution).
Re: Will beer freeze as a mixture (ethanol/H2O), or individually (only the H2O)
