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.Sponsored By:ProLeiT: cytiva: Berkeley Yeast: The Lupulin Exchange: BSG: Proximity Malt: Hopsteiner: Links:Poster 65 - Case study: Modeling fermentation data to predict and prepare for dry hop creep during in-package conditioning — WBC Connect 9.19.20 Poster SessionWorld Brewing Congress 2024Upcoming Events - Master Brewers CalendarJoin Master Brewers

Teddy Gowan discusses implementing a unit economic process for brewery transformation by analyzing costs for flagship beer. Topics include optimizing brewing processes, reducing costs, and empowering brewers through data-driven decision-making.

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.Sponsored By:ProLeiT: cytiva: Berkeley Yeast: The Lupulin Exchange: Precision Fermentation: BSG: Proximity Malt: Hopsteiner: Links:Presentation 12 - The Guinness Yeast and Irish Brewing Terroir — WBC Connect 9.29.20World Brewing Congress 2024Upcoming Events - Master Brewers CalendarJoin Master Brewers
