Yeah this is the process that Tactical Nuclear Penguin (~41%) and Sink the Bismark(~38%) use. They make the beer, then freeze it, as it thaws, the Alcohol and other non water impurities come out with some of the water first, the rest of the mostly water based iced (instead of impurity based ice) can then be tossed - litterally as it is a solid chunk.
You can do this at home by making popcicles with Kool-aid (or beer)... at the bottom of the popsicle holder will be all the flavor and sugar and ice at the top. You start eating it (flipping it over) and put all the tasty stuff first and are left with ice at the end.
I might try after racking a gentle stir tobring the watery beer and condensed beer back into more of a beer equilibrium..... Although a proper rack can do a lot of that for you.
