Today in 1973, US Patent 3712820 A was issued, an invention of Martin F. Walmsley and John Valentine Cross, and assigned to John Labatt Ltd., for their “Process for Making a Brewers’ Wort Beer.” There’s no Abstract, but in the description they explain that the “invention provides a process for producing a brewers wort in which an aqueous slurry of a raw starch containing material, preferably a cereal grain such as barley, is heated to 40 55 C. at which temperature it is subjected to the action of a discrete proteolytic enzyme and, optionally, a discrete ot-amylase enzyme, then heated to 65-90 C. at which temperature it is subjected to the action of a discrete a-amylase enzyme to solubilise the starch, after which it is cooled to 40-65 C. at which temperature it is subjected to the action of a discrete amylase enzyme or source thereof to produce fermentable sugars.”
