Swiss researchers brew the first AI beer


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.

Recently, members of an interdisciplinary research team from the Lucerne University of Applied Sciences and Arts (HSLU) were able to toast with “Deeper”, Switzerland’s first beer created by an artificial intelligence (AI). The hop-heavy Indian Pale Ale with a citrus note is the product of a joint research project by HSLU, der Rothenburger Microbrewery MNBrew and the Lucerne software company Jaywalker Digital.

157,000 recipes searched for samples

The AI ​​application “Brauer AI” (pronounced “Brewery”) acted as the digital master brewer for the project. She developed that Algorithmic Business Research Lab, a research group specializing in AI applications at the Department of Computer Science at HSLU. The suggestions of the “Brewers AI” are based on a database with 157,000 international beer recipes. With the help of so-called neural networks, the AI ​​searches for patterns in these recipes and derives its own creations from them.

“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.”
