A research team from the Lucerne University of Applied Sciences and Arts worked with the Central Swiss companies Jaywalker Digital and MNBrew to develop Switzerland’s first AI-based beer.
157,000 recipes searched for samples
“With hundreds of thousands of recipes, it is extremely difficult for breweries to keep track of things,” explains Marc Bravin, research assistant at the lab. “‹ Brewer AI ›can not only get this overview much faster than a person, but also provide suggestions for a beer that has really never been seen before,” he adds.
To do this, the beer style must first be determined – Indian pale ale, wheat, amber, etc. Either a person specifies this or the AI chooses it randomly. Based on the style, “Brauer AI” then suggests a list of malt types and their proportion in the brew. Next are suggestions for suitable hops and their cooking times.
Man controls “drinkability”
Before the brewing process, every AI-generated recipe is checked for suitability by a human master brewer using his specialist knowledge and adapted where necessary. Because: “The most original beer in the world is worthless if nobody wants to drink it,” says Adrian Minnig, the brewing expert at MNBrew. In his opinion, “Deeper” should meet with broad approval. “Very exciting and very fruity”, so Minnig’s conclusion.
The brewer sees the AI as an opportunity to test new and exciting combinations that he would not have come up with on his own. “The Swiss beer market is very dynamic,” says Minnig. “AI as a source of inspiration gives us a welcome head start in innovation.” Kevin Kuhn from Jaywalker Digital and AI researcher Bravin also emphasize that “Brewer AI” is not about excluding people from the brewing process. On the contrary: “Man and machine achieve the best results together.”
