“…One of the possible practical applications of the dielectrometry of high loss liquids is wine and juice (must) identification in order to determine their authenticity [4][5][6][7][8][9]. Wines and musts are high loss liquids, because the mass fraction of water in their composition is of the order of 75-90%.…”

“…As is known [7,8] the change in quantitative chemical wine composition (for dry natural wines) influences the CP change within the range of the order of some percent. Therefore, to solve the natural wine identification problem using CP as a basic measurement parameter it is necessary to have a dielectrometer that has much higher sensitivity with respect to CP deviation for high loss liquids.…”

“…We can avoid a measurement error due to a small volume of the liquid under test and air bubbles in it. In contrast a set of known measurement cavities, for instance, a liquid under test in a capillary placed into a rectangular waveguide [10] or a thin ring belt cavity with a liquid under test in a shielded cylinder dielectric resonator [6], can give some measurement errors.…”

The differential dielectrometer was designed to measure small differences in complex permittivity (CP) of two high loss liquids at frequency 32.82 GHz. The measurements are fully computer-aided with the exception of liquids filling and draining in the measurement cells. The time of one measurement cycle does not exceed 3 min. The dielectrometer is easy-to-work and can be used under the conditions of scientific and industrial physical–chemical laboratories. The sensitivity of the difference in the phase coefficients of the electromagnetic waves propagated in the measurement cells is better than 0.05% and that of the attenuation coefficient is of the order of 0.2%. The dielectrometer contains two measurement cells that are dielectric quartz cylinders surrounded by high loss liquids. We developed the CP calculation algorithm using the known CP of the reference liquid and the difference coefficients of complex wave propagation in the cells. The origins of the measurement errors are studied in detail and recommendations were made to avoid some of them. The dielectrometer can be used to express the identification of wine and must authenticity by means of their CP values. The CP measurement results for solutions of some substances that make wine and must composition are obtained. The possibility of using the dielectrometer for the detection of added water in wines or musts is shown.
