Master Brewers Podcast

What New Glarus prioritizes to maximize flavor stability. Special Guest: Dan Carey.

We look back at the last 70 years of innovations in brewing, we look forward to what the future holds, and we hear a pint full of great anecdotes from an author with whom we're all familiar. Special Guest: Charlie Bamforth.

Why Brewers Should Consider Alternatives to Tri-Clamp Special Guest: Travis Audet.

We dig into a couple of peer-reviewed papers from the Master Brewers Technical Quarterly (https://www.mbaa.com/publications/tq/Pages/default.aspx) that help us navigate the complexities of hop aroma and make better beer. Special Guests: Scott Lafontaine and Tom Shellhammer.

A study of 50 NA beers hunts for human pathogens. Special Guest: Grzegorz Rachon.

In 2018 Goose Island was plagued with a wild yeast contamination identified in post centrifuged products. This is how we systematically sought root cause, and ultimately eradicated the contamination despite our previous process understandings. Special Guests: Alex Nham and Joey Tidei.

The creator of infusion malts joins us to explain what they are and why they're special. Special Guest: Cristal Peck.

Did you know that the gelatinization temperature of your malt could be as low as 136F or as high as 154F? Charlie Bamforth's successor joins us to talk about variations in starch structure and what that might mean for your mash. Special Guest: Glen Fox.

The John Rowley approach to sour & funk Special Guest: John Rowley.

The story of how Creature Comforts Brewing tracked down and eliminated metallic off-flavor in kettle-sours. Special Guest: Spencer Britton.

An update from the fast-moving world of gene editing, as it relates to hops. Special Guest: Chris Willig.

For smaller brewers, yeast management can be a challenging prospect. Many mid-size to small breweries attempt to make a wide range of beer styles that require a plethora of yeast strains. Due to production limitations, brewers are often forced to stretch yeast pitching windows or purchase brand new yeast pitches at a dramatically high cost. A study was performed to evaluate potential media that would allow for adequate dormancy and viability of harvested yeast slurries for long term re-pitching opportunity. Various media were added to decanted yeast slurry and viability was measured over determined time periods to track health of the stored yeast. Results indicate that monopotassium phosphate, standard distilled water, alkaline mineral water, and a solution with sunflower oil all provide varying degrees of health preservation of long storage periods up to one month. Minimal changes were observed with adequate dilutions and these results will be discussed. Special Guest: Matt Couch.
