The composition of water significantly affect the flow of the process and the main indicators of the finished drink. The article presents the results of theoretical and experimental researches on improvement of the technology of preparation of drinking water for the production of non-alcoholic fermented beverages, in particular, bread kvass. The high efficiency of the application of natural minerals – clinoptilolite, rock crystal and activated carbon with combined treatment of water in the technology of bread kvass is proven. The quality and usefulness of the product depend on the content of its impurities. The integrated action of investigated materials with adsorption, ion exchange and redox properties provides water conditioning and achievement of the intensification of the technological process and high organoleptic qualities of the finished product. The work presents the physical-mechanical characteristics of the investigated materials, technological parameters of treatment, the influence of filter materials on the organoleptic and physical and chemical parameters of water and finished product. The article also gives a taste-aroma profile of bread kvass, made from the use of prepared water. The materials of the conducted research testify to the expediency of water treatment for the production of bread kvass in the sequence of clinoptilolite, active coal, rock crystal with a filtration rate of 8–15 m / h. In this case, the total iron content is reduced by 5 times, the total stiffness decreases by 75%, permanganate oxidation is 9 times. It has been established that such processing allows for high organoleptic qualities of prepared water and end product and increases the tasting score of bread kvass by 7 times, with no unpleasant taste and aroma that is characteristic of chlorinated water and decreases the turbidity of the beverage as a result of a decrease in the overall rigidity of water.
