An analysis of the complex dielectric permittivity of rum ʻHavana Club Añejo 3 Años' and its mixtures with methanol, ethanol, and deionized water is presented in this work. Measurements are carried out using the open-ended coaxial probe technique within a frequency range from 500 MHz to 15 GHz. Curves of the real and imaginary parts as well as the permittivity spectra (Cole–Cole diagram) and relaxation parameters of the liquids-under-test are presented. Distribution of the relaxation parameters for the different inclusion levels is analyzed and modelled. Comparison between the measured data and permittivity mixture theory is carried out; comments on the accuracy of each are discussed. A validation of the measurement process is realized by means of an evaluation of the experimental and literature dielectric permittivity values.
