Does a freezing point of 20C make sense for say, a bottle of cognac? Not really, or it would be frozen under room temperature. The link mentions 40% Isopropyl, which may be completely different than the alcohol you have in your bar, if that is the intention.
Alcohol freezes at -117 to -112 C, depending on the kind. 40% is pretty strong, but if its freezing point is any higher than the above figures, it is not by much.
This is why you can't make vodka ice-cubes. You'd have to dilute it with a fair amount of water perhaps. I've never tried it so I don't know if that would make it possible.
