Summit Brewing

Founded in 1986 by Mark Stutrud, the Summit Brewing Company has remained true to its roots and continues to focus on the Midwest and the Great Lakes region of the United States. Summit has also remained true to another core principle of its business activities: The brewery has always successfully met the challenge of reconciling growth, sustainability and profitability with the vision of brewing the best possible beer. An essential factor in this is the cooperation with Pentair.

"When we bought the DGM CO2 content meter in 2009, we entered the fascinating world of Haffmans analysis," says plant manager Tom Thomasser. Since then, Summit has trusted a wide range of Pentair Brewery Solutions. These include the CO2/O2 content meter type c-DGM as well as inline OGM content meters in the wort lines, filling lines and water lines and an Inpack TPO/CO2 meter type c-TPO

Another important milestone in the collaboration between Summit and Pentair resulted from the brewery's transition from sheet filtration to centrifugal beer clarification. This change in process created a need for deaerated water. Otherwise, oxygen could be introduced into the beer, which would have a negative effect on its taste stability and shelf life. It is well known that oxygen is one of the greatest enemies of beer.

For the Summit brewery, this means nothing more than more effective production time and more consistent beer quality. Both the membrane deaeration system and the carbonator, including the control unit and lines, were pre-wired and function-tested and delivered as a module. Both systems were therefore quickly and easily integrated into the production process of the Summit Brewing Company and put into operation.

Parallel to this modernization step, the brewery brought the carbonization of its beers up to the latest technology. Summit normally adjusts their CO₂ content via the bung pressure in the storage cellar. From time to time, however, post-carbonization had to be carried out in the pressure tank. That meant in case of the classic static procedure: Waiting time and significantly fluctuating degrees of carbonization. Consequently, a Carbo Controller CCR was integrated into the beer stream. This now guarantees the exact and fully automatic adjustment of the desired CO₂ content during ongoing production.
