Fermentation aid made of organic yeast hulls certified organic in accordance with European Regulation [Reg. (EC) N° 843/2007 and Reg. (EC) N° 889/2008]. It helps yeast metabolism providing physical support to the fermenting cells, helping CO2 liberation and absorbing toxic compounds present in the juice or produced during the fermentation.
This blend of DAP and tannin is contained in a special bag that gradually releases its content during fermentation. Nutriferm Gradual Release is to be added before the filling of the fermentation tank but it will start to release its content only at the end of the exponential growth phase of the yeast. By using Nutriferm Gradual Release, the second addition of nutrient is not necessary and its formulation guarantees a complete fermentation and the prevention of the reductive character. Recommended also for the fermentation in pressure tank.
Inactivated yeast. It absorbs auto toxic yeast metabolites and residual pesticides that can cause fermentation anomalies or the formation of off-flavors.
Inactivated yeast rich in sterols and long-chain fatty acids. Used at mid-fermentation, it helps maintain yeast membrane integrity and therefore prevent and correct fermentation anomalies. In case of stuck fermentation, its addition can help the fermentation restart without the need for another yeast inoculation.
Alcohol and high temperatures are the main factors that are responsible for stuck fermentations. These factors cause degradation of yeast cell membrane, 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 inactivated yeast, 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.
