Master Brewers Podcast

What is green chemistry? How and why should you apply it in your brewery? Special Guest: Dana Garves.

Beer consumption per capita in the US has declined steadily since 1980; meanwhile, consumption of wine, cider, and spirits has increased. Keith Armstrong (https://community.mbaa.com/network/members/profile?UserKey=c158a3db-642f-4178-af4e-68c787d6316b) joins us to talk about why, as well as what brewers should be doing about it. Special Guest: Keith Armstrong.

Brewing process and quality tips related to barley lipids Special Guest: Aaron Golston.

Understanding a particular beer's fermentability—and how it changes over time—is a prerequisite to managing in-package conditioning. It’s not uncommon to observe some level of over-attenuation during refermentation, similar to how forced-fermentation tests frequently finish at a lower gravity than production fermentations. In order to reduce the risk of over-pressurization in package, it’s important for brewers to quantify the expected over-attenuation for each brand. Typically, and ideally, the over-attenuation is consistent and can be accurately accounted for within priming sugar calculations. However, this is not always the case—especially with dry-hopped beers. At Allagash Brewing Company, we created a model for our Sixteen Counties brand in order to predict and more accurately account for variable levels of over-attenuation in package due to hop creep. Special Guest: Heather Muzzy Caron.

How a brewer who didn’t know the cost of his flagship beer, implemented a unit economic process that transformed the brewery from dry hopping to high gravity brewing. Special Guest: Teddy Gowan.

The Guinness brewery was founded in 1759 by Arthur Guinness. The Guinness brewery group were early exponents of the advancements in microbiology, and particularly yeast husbandry that took place in Europe at the end of the 19th Century. This led Guinness to establish the Watling laboratory in 1901 and subsequent St James’s Gate yeast Library. 16 Guinness yeast isolates were taken from the St James’s Gate yeast library and sequenced using next generation whole genome sequencing. Using Single Nucleotide Polymorphism (SNP) analysis, the genetic lineage of the Guinness yeast were established, with the Guinness yeast forming a monophyletic group (all descendants of a common ancestor). Previous yeast studies have attributed geographical location to domestication; using this information the Guinness yeast were placed with yeast domesticated in the United Kingdom and the United States. Within the 300+ yeast stored in the St James’s Gate yeast Library there are yeast from historical Irish Brewers. Using the same methods that established the genetic lineage of the Guinness yeast, 8 Irish brewing yeast were similarly assessed. In addition to the genotypic analysis of the Guinness and Irish yeast, the phenotype of the different yeasts were determined. In this paper we present an understanding of the Guinness and Irish yeast from a genotypic and phenotypic perspective. This analysis established that despite the different brewing attributes of these Irish yeast they all have a common genetic ancestry which is different to that of the United Kingdom yeast and the United States yeast. Consequently, we suggest that there is potential scope for an Irish brewing terroir concept based upon brewing with Irish yeast. Special Guest: Daniel Kerruish.

What is Kernza and does it belong in your next recipe? Special Guests: Alexandra Diemer , Harmonie Bettenhausen, Juan Medina Bielski, Tessa Peters, and Xiang Yin.

This is what happens when someone reaches out to suggest a great podcast topic. Becky Rudolf had questions about centrifuge operation so we mobilized a small army of Master Brewers members to provide answers. Special Guests: Andrew Conlon, Becky Rudolf, Christopher Clausen, Louwrens Wildschut, Marco Garcia, Morgan Harry, Steven Lyerly, and Zach Kelly.

We celebrate the first decade of craft malt by catching up with a few of its pioneers and talking about what craft malt can do for beer. Special Guests: Andrea Stanley, Brent Manning, and Todd Olander.

We take a deep dive into oak barrels. You'll hear about the properties of oak, the different types, and all about the complexities of seasoning and toast. Special Guests: Amy LaHue, Andrew Wiehebrink, and Noah Steingraeber.

A preview of the Olympics of brewing conferences, the WBC, which only occurs every 4 years and hasn’t been held in person since 2016 due to the pandemic. Special Guests: Lauren Torres and Sylvie Van Zandycke.

We go behind the scenes with the 3 moderators responsible for ensuring the highest possible quality content on the industry’s best technical brewing forum. Special Guests: Andy Tveekrem, Lars Larson, and Walter Heeb.

Does your brewery can or bottle? Do you pay close attention to your rinser or just assume it does what it's supposed to? This week on the show, we take a deep dive into water rinsers with a team of Master Brewers who collaborated to publish a Best Practices document you can use to get bottle and can rinsing done right. Special Guests: Ben Bailey, Dave Duff, Eric Samp, Heather Muzzy Caron, and Tim Lozen.

We thought we'd celebrate our 300th episode by giving John Bryce they day off...kind of. Special Guest: John Bryce.

We take a look at spirit barrel aging techniques from the perspective of Julian Shrago at Beachwood Brewing Special Guest: Julian Shrago.

A case study at New Belgium to understand the impact of can coatings on beer volatiles. Special Guests: Brooke Gushen and Nate Burns.

This week on the show, presenters from the Juicy Dry Hopping workshop in Calgary (https://mbaa.confex.com/mbaa/2019/meetingapp.cgi/Session/1081) join us to talk about their quest to maximize flavor, aroma, and efficiency in heavily dry hopped beers. Special Guests: Ben Edmunds, Daniel Sharp, Evan Partridge, and Ryan Dunnavant.

Adjusting expectations and processes to navigate an increasingly delicate malt supply chain. Special Guests: Curtis Davenport, Harmonie Bettenhausen, and Xiang Yin.

Our friends at Goose Island talk about their journey reducing TPO on small scale canning lines. This episode was recorded live during the 2019 Master Brewers Conference. Special Guests: Brooke Bell and Mike Kania.

Different paths of evolution and answers to questions about the genetic identity of commercially available yeast strains. Special Guest: Fabio Faria-Oliveira.
