Setting up Successful Fermentations: Yeast Attenuation and Wort Fermentability
The attenuation of a given yeast strain is a relative range because it can be heavily influenced by the wort fermentability or the composition of sugars extracted during the mash. On the hot side, we’ll overview how the brewer can manipulate wort fermentability in the mash and “set up the dinner plate” for a given yeast strain. On the cold side, we’ll dive into how different yeast strains can be used to consume more or less of the wort sugars and best practices to avoid attenuation problems stemming from poor yeast performance. We’ll apply this baseline knowledge and tackle more advanced technical challenges such as limiting ABV in NABLABs and targeting attenuation in dry-hopped beers.

Laura Burns, Ph.D. is the Director of Research and Development at Omega Yeast. After studying stress responses in Saccharomyces cerevisiae for her graduate thesis at Vanderbilt University, she decided the best place to apply this knowledge was in brewing. She worked in production brewing for five years as Head Brewer and Director of Quality Assurance before heading back to the bench at Omega Yeast. Her undeniable curiosity drives her to tackle difficult questions that brewers face daily.
