Today in 1903, US Patent 733284 A was issued, an invention of Otto Selg and Carl Guntrum, for their “Process of Converting Wort into Beer.” There’s no Abstract, although in the description it includes this summary:
This invention relates to an improved continuous process of converting wort into beer or other fermented liquid in a single apparatus and in such a manner that the beer is first thoroughly fermented and clarified before being impregnated with the carbonic acid gas. In this way the process is accelerated and a better product is obtained.
