Today in 1912, US Patent 1017086 A was issued, an invention of Henry E. Deckebach, for his “Process of Removing Alcohol From and Purifying Beer.” There’s no Abstract, although in the description it includes this summary:
The process of treating beer consisting of withdrawing it from the fermenting tub, passing heated, compressed air through it, carrying off the air, sending the beer a strainer, returning it from the strainer to the fermenting tub, and continuing the circulation until the beer has been lowered to the desired temperature.
