The present disclosure provides a portable device for controlling an alcoholic beverage that includes a single light source emitting a monochromatic excitation light beam of a wavelength between 350 and 650 nanometers, a beam splitter to reflect the light beam, a focus and collection lens, and a positioning device to orient the light beam along a direction substantially normal to an outer surface of the container. The positioning device positions the outer surface of the container at a predetermined distance from the focus lens. The device includes a filtering device for filtering fluorescence radiation captured by the focus lens to eliminate wavelengths shorter than or equal to the wavelength of the light beam. A spectrometer module produces a signal corresponding to the measured spectrum of the fluorescence radiation and an analysis module compares the measured spectrum to a reference spectrum.
