General Characteristics

Nutriferm PDC is a fermentation activator of entirely organic origin, created specifically for yeast nutrition during the preparation of the pied de cuve. Nutriferm PDC provides the essential elements to ensure good yeast growth and its survival in the difficult conditions of second fermentation (alcohol, pressure, lack of oxygen, low temperatures).

• Organic Nitrogen: made up of the amino acids that are easier to assimilate, it stimulates the multiplication of yeast and effectively prevents the appearance of reduced aromas.
• Vitamin B1: (thiamine) essential for the growth and multiplication of yeast. It is also a very important factor for the final quality of the sparkling wine. The use of thiamine, in fact, reduces the production of acetaldehyde, a compound responsible for the production of unpleasant notes of oxidized and grated apple.
• Survival factors and trace elements: long chain, saturated and unsaturated fatty acids, sterols and other compounds contributed by the hulls increase the alcohol resistance of yeast and stimulate the fermentation metabolism.
• Cell walls: solid substances that support yeast and act as adsorbents of toxic substances (short-chain fatty acids) and sulfur compounds produced during fermentation.
