Speakers: Bridget Gauntner, Dr. Darla Goeres
Biofilms, known to accumulate in draught beer lines, are self-organized communities of microbes that may also contain beer stones, proteins, and/or lipids. Biofilms are more tolerant to disinfection than isolated microbes, and removing an established biofilm from a system is challenging.
In this presentation, Bridget Gauntner, Brewers Association (BA) Draught Beer Quality Subcommittee Chair, discusses the guidelines endorsed by the BA for cleaning beer draught lines. Following this brief introduction to the Draught Beer Quality Manual, Dr. Darla Goeres, Research Professor at Montana State University, shares the results of a BA funded research study to understand the impact repeated exposure to cleaning chemistries has on biofilm growth, kill/removal, and subsequent regrowth in beer draught lines.
