Milwaukee brewpub operation utilizes Draught Guard to protect quality, mitigate safety risks of chemicals, and save over $20,000 each year.

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

With two breweries and taprooms in the Milwaukee area, The Explorium Brewpub specializes in small batch, craft beer. Committing 28 hours of labor and dumping over $1000 of beer each month to clean lines, Explorium implemented Draught Guard to minimize beer wastage and cleaning costs, mitigate chemical use, and ensure the highest quality of tap beer.

Average length of line


My brew staff was cleaning lines monthly which required about 28 man hours a month for our 56 draft lines which average 85’ runs. Now, with Draught Guard, we clean quarterly with excellent results. I save an extraordinary amount of time and money using this system.

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 12 weeks with no chemicals run through the system, Draught Guard treated lines maintained the average ATP count of lines flushed with caustic every two weeks. Regular two-week faucet and coupler maintenance is still recommended and encouraged.

After a full quarter, Draught Guard treated lines were on average just as clean as lines cleaned monthly with caustic
