Our friends from Saint Arnold Brewing Company in Houston describe how they reduced lauter times, decreased their grain bills by 5%, and increased average brewhouse efficiency from 89.3% to 95.5%. Special Guests: Drew Russey and Eddie Gutierrez.

Our friends from Escarpment Labs (EP102 (https://www.masterbrewerspodcast.com/102)) discuss the impact of inoculation rate on Norwegian kveik yeast fermentation. Special Guests: Iz Netto and Richard Preiss.

Our friends from a "large" craft maltster and a "large" craft brewer get together to talk about craft malt, winter barley, AMBA's guidelines for all-malt brewers, and more. Special Guests: Dave Kuske and Tim Matthews.

This week on the show, a topic that we should all be considering: sustainability. Amy (Johnson) Dragon describes how she went about reducing the solid waste that Genesee Brewing Company sends to the landfill. Special Guest: Amy (Johnson) Dragon.

This week on the show, we get a glimpse at life inside a brewer's yeast supply lab (http://jasperyeast.com/). You'll hear about tips for ordering yeast, how to better align expectations with reality, and of course, when to blame the maltster. Special Guests: Jasper Akerboom and Travis Tedrow.

Saccharomyces cerevisiae var. diastaticus is a beer spoilage yeast, with contamination leading to off-flavors, over-attenuation, and over-carbonation, potentially causing gushing beer, exploding packages, or non-compliance with Alcohol by Volume reporting. 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 lab. Matt Linske joins us live from the 2019 Master Brewers Conference (https://www.masterbrewerspodcast.com/master-brewers-live) to discuss his evaluation of Farber Pham Diastaticus Medium (FPDM) for the enrichment and detection of diastaticus, and prov

An elite group of brewers working behind the scenes to improve hop quality in the US. Special Guests: John Mallet and Tom Nielsen.

What if you could postpone buying new fermentors by reducing variability during fermentation? This week on the show, you'll hear about how this was accomplished at New Belgium while eliminating inaccurate measurements like yeast cell counts & viability. Special Guest: Peter Bouckaert.
