Case Western Reserve University chemical engineering PhD students win three brewing categories at professional conference in Boston
CLEVELAND, OH —Two teams of Case Western Reserve University chemical engineering PhD students recently walked away with a trio of top awards in a competition with
dozens of other aspiring scientists. In brewing beer.
The Case Western Reserve teams won three of the seven categories at an annual conference of the American Institute of Chemical Engineers (AIChe). The institute’s fourth annual beer-making competition in Boston was sponsored by the AIChe's Young Professional Committee.
The teams (The Brew Crew: Spooky Beers for Chemical Engineers; and Over the Hops CWRU Brewing) are really just casual group of about eight friends who happen to love
both chemistry and beer. In the early days of the COVID-19 pandemic in 2020, they began to meet up at each other’s homes for brew parties.
“They really were several-week parties—one weekend for ‘the boil’ and then a meet-up later to bottle it,” said Bethany Kersten, a member of the Over the Hops team with fellow PhD students Will Dean and Drace Penley. “We were just having fun, but found out we can make pretty good beer.”
For the competition, the Over the Hops team brewed up beers like “Coraline’s Brew,” a high-powered (8.8% alcohol) black IPA; and “Toasty Oat,” a smooth, lower-alcohol (5.1%) oatmeal stout. Another beer featured hops grown in locations related to wherever each of them attended undergraduate school: Ohio, Minnesota, Idaho and so on.
“We’re all IPA drinkers and that Black IPA was our favorite,” said Kersten, whose research at Case Western Reserve focuses on studying the electrochemistry of actinides
for recycling of nuclear fuel. “It’s sort of a wintery IPA and it was a big hit at the competition, at least based on the blind taste tests that people could take.”
Dean said the team went for a more “drinkable beer” with the stout, which has notes of coffee, peanut butter, nutmeg and vanilla—and low bitterness.
The Over the Hops team was judged as having made the “the Most Efficient Brew” and named the best new team. The Brew Crew concocted “Poison Apple Ale” and two others, but won first place for its scientific poster showing the brewing process (attached).
Chris Wirth, an assistant professor in chemical and biomolecular engineering who helped the students set up the AIChe trip, said many of the same principles fundamental
to chemical engineering are used in brewing beer.
“Concepts like heat transport and mixing are as useful when brewing beer in your kitchen as if you’re making millions of barrels for Stella or whomever, it’s much of the
same science,” Wirth said. Dean, whose research focuses on understanding the bulk and interfacial properties of
new electrolytes for energy storage devices, said even a decision like how much sugar to add during the brewing process is critical.
“Home brewers have tales of bottles exploding because they had too much sugar,” he said. “They cap it and the CO2 has nowhere to go.” Penley, who researches developing electrolytes for lithium batteries, said the student-
scientists would likely keep on with their casual brewing.
“Chemical engineers like making beer because they can make it at home—and they can make it well,” Penley said. “The science here is knowing when you add the hops, knowing when the alpha acids will come out of those hops. But there’s also an art to it, so that in the end, you’ve just got good beer.”
Over the Hops CWRU Brewing - Best New Team, Most Efficient Brew
Will Dean - Research focuses on understanding the bulk and interfacial properties of new electrolytes for energy storage devices; hopes head his own research lab, continuing to work on energy storage technology.
Bethany Kersten – Research focuses on studying the electrochemistry of actinides for recycling of nuclear fuel; hopes to continue research, work in a national lab
and move into a climate-policy position.
Drace Penley—Research focuses on developing electrolytes for lithium batteries; hopes to continue on as a postdoctoral researcher post-graduation and eventually
land a faculty position. Rachel Beller—Research focuses on electrode reactions in batteries; hopes to
work at a national lab or do research in industry.
The Brew Crew - Best Poster
Maura Sepesy—Research focuses on membrane separation for medical isotope purification; hopes to teach and encourage the next generation of future scientists.
Jacob Hostert—Research focuses on nutrient-recovery using peptides; hopes to use academic skills to improve the environment.
Marola Issa—Research focuses on complex fluids/soft matter and working to measure transient rheology in drying coatings; hopes to one day become a
thought leader in field and start her own business.
Hairou Yu—Research focuses on the adhesion of soft particles to boundaries; hopes to teach and conduct research for entire career.
