Abstract
Multi-wavelength and multi-angle absorption spectroscopy performed in the visible spectral range, that is, 'scattered colorimetry', has been used to map a library of 25 diverse and commercially-available Belgian light beers. The resulting map shows four main clusters, relative to blonde, amber, red, and weiss beers, respectively, demonstrating that scattered colorimetry is a valid method for beer authentication and fingerprinting.
