The Masters Championship of Amateur Brewing (MCAB) is a grass roots amateur brewing championship. The format of the MCAB is a small invitation "champions' championship," where amateur brewers compete head-to-head under ideal conditions, and with the highest standards of judging. Fourteen local competitions in North America have been selected as MCAB Qualifying Events. Edmonton is the only Canadian site. First place Qualifying Styles at each Qualifying Event receive an invitation to enter the MCAB finals in that style category. MCAB entrants are free to enter any one beer they wish in their Qualifying Style, including samples from fresh batches brewed specially for the MCAB. This format allows MCAB entrants to brew and submit beers at peak levels of freshness and conditioning, and have their beers judged in small flights by panels of highly experienced judges.
