An algorithm is proposed for using the combination of NMR spectroscopy of 1Н and deuterium 2Н(D) nuclei for prompt identification and determination of the component and differential isotope composition of water organic solutions including values in ethanol, water in wine, cognac, brandies, juices, soft drinks and other products. The method does not require sample preparation and/or use of any certified reference materials. Some examples of the proposed concept application for the authentication and quality control of wine products are presented.
