Efficiency of brewing determined by the duration the basic processes of technological cycle. The main and longest stage is the fermentation of beer wort and maturation of young beer. One o f directions for improving the efficiency of ferm entation is the use drugs active dry yeast. The main advantage o f dry yeast is their accessibility, flexibility in use, ease transportation and the possibility of long-term storage. Reproduction of yeast in beer wort is limited due to the lack of nitrogen assimilating, salts of zinc, iron and pantothenic acid. Lack of iron can be compensated magnesium ions, the concentration of which exceeds several times the need yeast, while the limit for zinc ions, pantothenic acid and amine nitrogen can be filled with the introduction of these components in beer wort. With this aim in obtaining beer for enrichment growth factors and micronutrients using various drugs and «nutrient» for yeast. For exploration was accepted yeast strain Saflager W-34/70 of Weihenstephan, which used in the brewing industry to produce beer of bottom fermentation. This strain provides a well-balanced beer with a fruity and floral aroma and delicate taste. Race has a high capacity for form ation flakes and total content of residual sugar 5 g/ch, corresponding to 83% of the apparent ability to fermentation. For comparison,was made a control without making wort researched BAR. During the work in a production environment to activate the life of dry yeast race W 34/70, was expediency the using of inorganic BAR in technology of two sort of beer -«O pillya «Haidamatske» (light) and «Opillya«Knyage» (dark).
