Master Brewers Podcast

An overview of the options for pasteurizing beer, and how pasteurization works at Goose Island. Special Guests: Gus Grosenbaugh and Michael Owens.

Filling equipment within a brewery is ironically one of the best places for microbial growth to thrive. There are nooks, crannies, and blind spots that beer can sneak into, which are also challenging to clean. Beer filling equipment is also constructed using a variety of different materials that require specifically tailored cleaning chemicals to prevent corrosion while working effectively to remove soil. Every brewery has a different filling operation including equipment, surrounding space, and utilities, therefore different needs for chemicals and cleaning practices. As a brewery optimizes its filler cleaning practices and chemicals, it is also essential to validate that the chemicals and method of cleaning are both working effectively. To avoid having every brewery reinvent the wheel with filler cleaning practices and save the time and money it takes to trial new processes, this presentation will share one brewery’s story of developing a robust cleaning program on both of its canning lines. We will discuss

What's the buzz in omics all about and how can it help you make better beer? Special Guests: Glen Fox, Harmonie Bettenhausen, and Laura Burns.

The Inspiring History and Legacy of American Lager Beer is envisioned to be a nine-volume series of books covering the history of the American lager brewing industry from the 1840s to the 1940s and the evolution of adjunct lager beer as America’s “national beverage.” The “surprising” aspect of this history is that it ever happened at all, given the half-century-long assault on the industry between the 1870s and 1910s to impose an “American Reinheitsgebot.” Unified in this objective were a plethora of the nation’s political, cultural, and agricultural institutions—all seeking to ban to use of rice and corn-based products in the brewing of American ales and lagers. Equally united in opposition to this effort were the brewers and brewing scientists of America. In battles that were passionate, highly public, and intense in nature, these brewing industry advocates successfully defended the right of American brewers to brew with the ingredients of their choice. It is a powerful legacy not only for America’s first r

A deep dive on beer foam with a couple of familiar guests, one of whom literally wrote the book on foam. Special Guests: Ashton Lewis and Charlie Bamforth.

Just when you thought light-struck flavor in beer was permanent... Special Guests: Catherine Villa and Keith Villa.

A couple of experts offer tips to help your brewery beat the summer heat. Special Guests: Nick Donofrio and Rissa Spalding.

Kerry Caldwell suffered severe injuries from an accident in the brewhouse. She was airlifted and overcame the 34% chance of survival calculated by the hospital. This episode is both the story of her accident and a description of a simple, inexpensive device that should be installed in your brewery to prevent similar accidents.  Special Guests: Kerry Bloxham (Caldwell) and Scott Zetterstrom.

If you have the same canning line as Jack, you might want to listen up. Special Guest: Jack Van Paepeghem.

Noise exposure may not be on your brewery's radar, but this is an area in which an ounce of prevention is worth a pound of cure. Special Guest: Jonathan Borntrager.

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 metho
