Milwaukee craft brewery utilizes Draught Guard to minimize cleaning costs, labor, and time, and ensure the highest quality of tap beer.

Validation Phase of Draught Guard

Beginning in the summer of 2018, Draught Guard set out to run a series of data collection pilots to demonstrate and prove the effectiveness of the Draught Guard technology in maintaining draught line cleanliness. Each pilot lasted at least eight weeks and began with a regular, Brewers Association recommended chemical clean. For the remainder of the pilot, the selected lines were only treated with Draught Guard and had zero chemicals run through them. Regular faucet and coupler maintenance continued throughout the pilot, as Draught Guard's main focus is the beer line itself and makes no claims of maintaining faucets and couplers. Line cleanliness was monitored via ATP and dip slide testing. Measurements were taken every two weeks.

Pilot Overview

Based in Milwaukee’s Harbor District, Component is a hobby–turned–obsession craft brewery. The brewery, owned and operated by three cousins, is the team’s tribute and contribution to the city’s thriving and legendary brewing history. The team at Component implemented Draught Guard to minimize the time, labor, and wastage associated with bi-weekly line cleaning, and to ensure the highest quality of tap beer.

"At first, we were skeptical about installing this on our tap system. After a few weeks of searching for anything that might resemble an off-flavor, we gave up and declared Draught Guard the winner. I am confident that Draught Guard is keeping our lines in great shape between regular cleanings. The beer is being presented as the brewers intended and we are saving time/money by extending the time between line cleanings."

ATP Results

ATP testing was utilized to compare Draught Guard treated lines over an extended period of time to the BA recommended two-week caustic cleaning cycle. After eight weeks with no chemicals run through the system, Draught Guard treated lines measured 76% fewer ATP counts compared to lines flushed with caustic every two weeks. Regular two-week faucet and coupler maintenance is still recommended and encouraged.
