It has been proved in the respective investigations that it is possible to run a shortened for mentation of beer wort in 12.5°Blg at the temperature of 18°C within 6 hours with the use of immobilized yeasts and shortening the beer maturing time (0-3°C) about 20 days. The effect of process conditions on the chemical composition and beer quality discriminants was investigated. Higher content of fusels, diacetyls and esters as compared to the control beer, decreasing with the maturing time, has been found.
