Post Webinar Q&A
Process control for diacetyl is as pertinent to brewers today as it was when brewers produced the first North American lager in 1842. Traditional critical control points for diacetyl, aside from robust hygiene programs to prevent diacetyl contributions from contaminating lactic acid bacteria, have long focused on fermenting and aging processes. This webinar will begin with a series of questions seeking to challenge participants’ paradigms concerning the production and control of diacetyl. Subsequent to this survey, the focus will shift to four strategies for realizing process control for diacetyl, emphasizing the critical impact of variability in time, temperature, and pH play in each strategy. Additionally, this webinar will show how each value-added step in malting, brewing, and yeast management influences control. Participants will leave the webinar with practical food for thought to help their breweries apply improved process control for diacetyl!
