Scientists turn to AI to make beer taste even better

Whether you prefer a fruity lambic or a complex Trappist, Belgian beers have long been famed for their variety, quality and heritage. Now, researchers say they have harnessed the power of artificial intelligence to make brews even better. Prof Kevin Verstrepen, of KU Leuven university, who led the research, said AI could help tease apart the complex relationships involved in human aroma perception. "Beer – like most food products – contains hundreds of different aroma molecules that get picked up by our tongue and nose, and our brain then integrates these into one picture. However, the compounds interact with each other, so how we perceive one depends also on the concentrations of the others," he said.
