Granite City Food & Brewery Ltd., an 18-location Midwestern restaurant chain, has been granted a patent by the United States Patent Office for a proprietary beer brewing process that they call Fermentus Interruptus.
The Company uses a central brewing location for the production of unfermented and unprocessed hopped wort and then transports the liquid to its restaurants. The brew is then placed into fermentation tanks where it is finished into beer. The process cuts down on the equipment and labor costs associated with running separate brewpubs. Because the liquid being transported across state lines is not finished beer, the company does not have to involve distributors in the shipments.
Granite City says the proprietary process will allow it to continue its geographic expansion.
