Predicting the Taste and Quality of Beer with Artificial Intelligence

Belgian researchers have successfully developed models of artificial intelligence that can predict how consumers will rate the flavor of a beer and the compounds that can enhance it. This research, published in Nature Communications, has the potential to revolutionize the food and beverage industry.

Kevin Verstrepen, a professor at KU Leuven and director of the VIB-KU Leuven Center for Microbiology and the Research Institute of Microbiology, is leading this innovative approach to beer research. The team began by chemically analyzing hundreds of beers, measuring the concentrations of numerous aromatic compounds. A panel of 15 trained individuals evaluated each beer based on 50 criteria to create a detailed tasting report.

This comprehensive data collection allowed the researchers to use artificial intelligence to predict the key aromas and overall appreciation score of a beer without human intervention. After five years of meticulous work, they successfully used AI to improve the flavor of a commercial Belgian beer by adding specific aromas predicted by the model. The modified beer performed significantly better in blind tastings, showcasing the power of this innovative approach.

Michiel Schreurs emphasizes the complexity of beer flavor, stating that computers are essential for predicting taste accurately. This technology can also be applied to other food products, making it even more groundbreaking in food and beverage development. The team is now focused on developing better non-alcoholic beer using their AI model, with plans to create a cocktail of natural aromatic compounds that mimic alcohol without side effects.

Overall, this research represents a significant breakthrough in food and beverage development and has far-reaching implications for both industries.
