Guests at the next Beer with a Scientist event will hear about the science used in the fermentation and distillation of another adult beverage – whiskey. Kevin Smith, a distillery manager for Brown-Forman Corporation, will discuss how microbiology is used in making whiskey and address the challenges of preserving these skills in an era of advanced technology.
“Fermentation science goes beyond the microbiological aspects related to yeast, lactic bacteria used in the sour mash process and the control of microbial contaminants. Other biological processes we must wrangle are grains, grain quality and the enzyme systems in malted barley, which are critical to breaking starches in grain down to metabolizable sugars,” said Smith, a Louisville native who earned a master’s degree in environmental microbiology from UofL.
Smith will explain how modern yeast handling practices and industrial equipment for distillery sanitation allow for improved consistency, quality and sensory character of new whiskey. He also will describe how individual yeast strains affect a whiskey’s flavor.
The event begins at 8 p.m. on Wednesday, April 5, at Against the Grain Brewery, 401 E. Main St. in Louisville. A 30-minute presentation will be followed by an informal Q&A session.
Admission is free. Purchase of beer, other beverages or menu items is not required but is encouraged.
