8-Week pilot conducted to evaluate Draught Guard on a remote system stretching over 200ft long, with over $8,600 projected in annual savings.

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 Green Bay, WI, Hinterland is one of the state’s most recognized craft breweries. Located in Green Bay’s Titletown District and across the street from iconic Lambeau Field, Hinterland is founded on the idea of challenging your palate to a killer brew with a rich heritage and bold passion. This pilot was overseen by Jake Hornick (Director of QA/QC) and Joe Karls (Brewmaster).

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 48% fewer ATP counts compared to lines flushed with caustic every two weeks. Regular two-week faucet and coupler maintenance is still recommended and encouraged.
