Alcohol and high temperatures are the main factors which are responsible for stuck fermentations. These factors cause degradation of the cellular membrane of yeast, which results in the loss of the ability to use sugar. The addition of Nutriferm Advance at 1/3 fermentation prevents irregular kinetics while maintaining an efficient sugar transport system until fermentation is complete. A complex additive made from yeast hulls, ammonium phosphate and cellulose, it helps yeast with alcohol tolerance and exerts a detoxifying action, thus assuring optimal aroma cleanliness while preventing the formation of hydrogen sulfide.
