Brewing industry is one of the most progressive and dynamically developing areas of the food and beverage industry in the world. In Kazakhstan brewing is currently the most developed segment of the beverage market. In recent years, production capacities have been increasing, the range of products has been expanding, and craft brewing has been developing. Non-alcoholic beer is becoming more and more popular. The production technology is carried out in two ways - it is the dealcoholization of the finished drink, or a change in the technological processes of production. In the presented article, the possibility of preparing a low-gravity wort and fermenting it with various strains of yeast for the preparation of non-alcoholic beer is investigated. The technological characteristics of three types of yeast used for the production of low-alcohol drinks, fermentation activity and absorption of solids during fermentation were studied. It has been established that the yeast strain Saf Brew TM LA-01 has the lowest degree of fermentation and is most suitable for the fermentation of low-gravity wort in the production of non-alcoholic beer. The mode of fermentation and post-fermentation of beer has been selected, as a result of which the content of ethyl alcohol does not exceed 0.5 vol.% and contains fermentation by-products in quantities corresponding to established standards.
