Master Brewers PodcastEpisode 069: Diastaticus - Part 2Over-carbonation. Exploding bottles. Lawsuits. Super-attenuation caused by diastaticus contamination is a hot topic in the brewing industry. We bring you interviews with brewers, yeast suppliers, and independent microbiologists to talk about detection, prevention, and more. Whether your strategy is to keep diastaticus out of your brewery altogether or to manage it alongside other Saccharomyces cerevisiae strains lacking the STA gene, you're guaranteed to learn something from these interviews.Special Guests: Andy Tveekrem, Matt Linske, Matthew Peetz, Michelle McHugh, Sylvie Van Zandycke, Tobias Fischborn, and Wade Begrow.Sponsored By:Novozymes: Brew Ninja: Precision Fermentation: Gusmer: BS...2021-12-2735 minMaster Brewers PodcastEpisode 068: Diastaticus - Part 1Over-carbonation.

Many diastaticus yeast are commercially available, high-attenuating strains, but wild strains have also been isolated in beer. Regardless of the source of contamination, re-fermentation of finished beer by diastaticus is caused by the secretion of a glucoamylase. In finished beer, glucoamylase breaks down unfermented dextrins, creating newly fermentable carbohydrates. Outside of PCR-based genetic screening, there exists no easy method for detection of diastaticus contamination by the brewery quality control...2019-12-0226 min
