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

Located within Milwaukee’s historic Pabst Brewery, and a partner of the Brewhouse Inn & Suites, Jackson’s Blue Ribbon Pub is known for its lively environment, all-American pub food, and wide variety of drinks. Jackson’s keeps things local keeping things local by featuring 13 Wisconsin beers on tap – ranging from some of Milwaukee’s best craft breweries, to classic Miller Lite, to Wisconsin staples such as New Glarus Spotted Cow.

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 measured 83% fewer ATP counts compared to lines flushed with caustic every two weeks. Regular two-week faucet and coupler maintenance is still recommended and encouraged.
