9-Week pilot conducted to evaluate Draught Guard on a remote system stretching over 100ft long.

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

Home to Milwaukee’s largest and most authentic Oktoberfest, Bavarian Bierhaus is a staple in the Milwaukee area. Reimagined in 2016, the new Bavarian Bierhaus features a 350 person beer hall, a 15 bbl brewery, tap room, and multiple indoor and outdoor spaces. The brewery produces over 200,000 house-brewed beer – eight of Bavarian’s beers are available on tap in addition to several guest beers.

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 nine 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.




7.5 Months

9 Weeks

Longest draught line in system, with signal measured and verified throughout entire run

Projected annual savings in beer wastage and cleaning costs

Rapid ROI

Line cleanings extended from every two weeks to every nine weeks
