Iconic pioneering craft brewery utilizes Draught Guard to maintain line cleanliness, reduce beer water wastage, and uphold draught quality.

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

Started in 1987, Lakefront Brewery is one of the original pioneers of the craft beer industry and is one of Wisconsin's largest craft breweries. Mindful of waste and impact on the environment, Lakefront sought out Draught Guard to minimize beer wastage and cleaning costs, mitigate chemical use, reduce water consumption, all while protecting their beer served on tap.

"Kevin and Mark with Draught Guard have been easy to work with from the start. Along our 8 week trial, they did everything in their power to make sure we (and our whole team) were comfortable with the process, and on more than one occasion they went out of their way to prove their product is worthwhile. It goes a long way when a company is so willing to show their value, and that's exactly what they did. We are excited to be using this technology that will allow us to save on the time, labor, and waste spent cleaning our lines so frequently. What's even better, is feeling comfortable knowing that our brand and beer will still be well represented thanks to their service."

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 55% fewer ATP counts compared to lines flushed with caustic every two weeks. Regular two-week faucet and coupler maintenance is still recommended and encouraged.


Dip Slide Results

Dip slides provide a quick, reliable and effective means of determining bacteria levels present in water samples. Testing the push water flushed through the beer lines at Weeks 0, 2, 6 and 8 of our pilots, dip slide information reveals that Draught Guard in fact outperformed the regular two-week caustic cycle.
