Given the highly competitive environment of brewing industry today, businesses need to constantly develop new products of high quality and nutritional value that meet consumer and sanitary requirements. Therefore, the production of beer-based mixed beverages using nontraditional raw plant materials is gaining popularity. It is quite possible to produce these types of beverages at brewing facilities of Almaty and the Almaty region since it presents a favorable climate to develop agricultural businesses producing fruits and berries and has a large potential for using wild crops. Using of these plants will keep the enterprise economically viable by expanding the assortment of products and increasing the share of low-alcohol beverages in total production. In this study, the purpose is to select the optimum method for the production of special beer based on apple and grape juice. The choice of these particular types of raw plant materials was due to their wide availability and suitability for juice processing. The methods of introducing juice into young beer after the post-fermentation stage, as well as the introduction of fermented juice into young beer, were applied in the production of a mixed beverage. The organoleptic, physicochemical properties of the finished beer made using two methods have been studied. As a result, the optimal beer to juice ratio of 70:30 was selected according to the first method. This method resulted in the most balanced combination in terms of organoleptic characteristics, but colloidal instability was observed. For the second method of special beer production, the Oettinger Pils yeast race was used for fermentation of the juice base that was introduced into young beer after the post-fermentation stage. The resulting beverage at the 50:50 ratio of beer to juice was highly stable and had the highest organoleptic and physicochemical qualities.

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.

The production of non-alcoholic beer requires brewing wort with a low degree of digestion. That is possible with the use of non-traditional raw materials in production. The research object presented below is grain sorghum varieties Kazakhstan-16 and Kazakhstan-20. Nowadays, the production of non-alcoholic beer with technological methods is not studied enough. Therefore, plants with small capacities cannot produce it. This study justifies the use of grain sorghum to produce low-digestion wort. In addition, we justify that Kazakhstan-16 had the best indicators for producing non-alcoholic beer. The following ratio of malt for wort preparation to sorghum 60:40 and hydro module 1:6 are proposed. The prepared wort had an extractivity of 6.62 % and digestible carbohydrates of 25.89 % of the total. The ratio of digestible sugars to non-fermentable substances in the wort was 1:1.79, so 79 % constituted mainly non-fermentable sugars. Mathematical experiment planning has been used to study the effect of malt and sorghum filling ratio and hydro module on the brewing wort's extractive matter yield. Based on the results of this study, the brewing wort has a low digestion rate. However, the carbohydrate composition of the wort is due to the presence of mono- and disaccharides. This wort will produce a beer with an ethanol content of up to 0.5 % of alcohol and the organoleptic characteristics set. High extractivity in the raw materials and their high gelling temperature account for these results. These factors made it possible to select a jumping mashing regime, which resulted in deep hydrolysis of the sugars into dextrins. This study will allow using non-traditional grain raw materials and producing non-alcoholic beer in breweries of any capacity. These methods are cost-effective and do not require expensive equipment
