patent-logo
Today in 1969, US Patent 3453114 A was issued, an invention of Peter D. Bayne and John L. Pahlow, assigned to Schlitz Brewing Co., for their “Process of Brewing.” There’s no Abstract, although in the description it includes this summary:

This invention relates to a process of brewing and more particularly to a process and apparatus for reconstituting concentrated brewers wort.

The present invention is directed to a continuous, high capacity process for reconstituting concentrated wort. The wort is reconstituted without color gain, loss of hop bitter or alternation of flavor. According to the invention, concentrated wort at a temperature of from 60 to 120 F., but preferably under and having a solids content of 80% is continuously pumped from a storage tank and/ or shipping containers and passed 4into a mixing system. Deionized water, -or filtered mains water, depending upon the purity of the water, is introduced into a mixer at a constant flow rate and is mixed with the stream of concentrated wort to partially reconstitute or dilute the wort. In some cases, particularly in high capacity installations, a second mixer in series may be employed and -a second stream of either deionized water or filtered mains water is introduced into the second mixer down stream from the first mixer. This second or breakdown stream of water is continuously introduced at a variable flow rate and mixed with the partially reconstituted wort to complete the reconstitution to the fermentation gravity.
