eNose Technology Distinguishes Genuine from “Fake” Beer

A recent study conducted by the German, Austrian, and Swiss Pediatric Pulmonologists (GPP) sheds light on a lighter side of scientific inquiry – beer consumption during academic gatherings. The unsystematic observations of the GPP led them to ponder a peculiar question: Can an electronic nose (eNose) differentiate between real beer and fake beer?

In a single-center experimental study, the researchers analyzed 12 different types of “real beer” and one “fake beer” using the eNose, a technology typically used for disease screening through exhaled breath analysis.

Each beer type emitted a unique volatile organic compound (VOC) smell print, allowing the eNose to distinguish between them with remarkable accuracy. Even more fascinating was the differentiation between bottom- and top-fermented ales. And to the surprise of the researchers, “Sylter Hopfen”, marketed as a “champagne-beer” and representing the “fake beer,” stood out distinctly from all other genuine beer types.

While providing the first objective data on beer flavor, the researchers suggest that the eNose could potentially help settle the age-old debate on beer flavors and bring harmony to the world.
