Today in 1968, US Patent 3403029 A was issued, an invention of Emil A. Malick, assigned to Phillips Petroleum Co., for his “Reconstituted Beer Process Using Fractional Crystallization.” There’s no Abstract, although in the description it includes these claims:

Reconstituted beer is formed by fractionally crystallizing a beer product to form a concentrate containing some precipitate and a separate precipitate containing fraction, holding at least the concentrate at the temperature of the fractional crystallization process to allow additional precipitation to take place, heating at least the concentrate to allow redissolving of flavor bodies and the like from the precipitate, combining the heated concentrate and separate precipitate containing fraction, and separating precipitate from the combination.
