Fermoplus Premier Cru is a nutrient formulated to assist the action of yeast during the fermentation of structured red wines, rich in extract and tannins. Fermoplus Premier Cru contains enzymatically pre-treated yeast hulls that provide a high concentration of sterols and promote sugar depletion, thus preventing increases in volatile acidity. Through the action of its ellagic tannins, it lessens the formation of olfactory defects, mahes oxygenation more effective and increases colour stability.
