Master Brewers Podcast

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

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.
