ENARTIS NUTRIENTS

Nutriferm Arom Plus

NUTRIFERM AROM PLUS is a nutrient produced from yeast that undergo enzymatic lysis followed by physical separation and concentration of free amino acids.
NUTRIFERM AROM PLUS complements the amino acid profile of juice and supplements aromatic precursors used by yeast in the early phase of fermentation to make aromatic compounds.
NUTRIFERM AROM PLUS also provides survival factors (sterols and long-chain unsaturated fatty acids) which help with yeast viability thus ensuring successful fermentations.
The unique production process used to produce NUTRIFERM AROM PLUS eliminates yeast by-products responsible of bitterness and dryness. Consequently, NUTRIFERM AROM PLUS enhances sweet perception.

Nutriferm Special

Nutriferm Special adds the elements and nutrients necessary for correct fermentation metabolism in must, allowing the selected yeast to express the physiological characteristics for which it has been chosen.
The use of Nutriferm Special is particularly recommended in musts that have been over clarified, a condition that often results in poor or incomplete fermentation, which may be accompanied by increases in volatile acidity. In these situations, the contribution from inactivated yeast is two-fold: it supports fermenting yeast and contributes long chain unsaturated fatty acids (C18, C20) essential to regulate the permeability of cell membranes.
Nutriferm Special is also for the treatment of stuck fermentation as the nitrogen it contains stimulates yeast metabolism while the cell walls present in the autolysate adsorb medium chain fatty acids (especially C8, C10) and their esters, compounds toxic to yeast and responsible for fermentation defects.

Nutriferm Energy

At the beginning of metabolic activity, yeast have nutrient requirements if unmet, put successful completion of fermentation at risk. Nutriferm Energy contains amino acids, organic nitrogen, micronutrients, vitamins, mineral salts and survival factors which are immediately available to meet these requirements. Nutriferm Energy provides alpha amino acids, trace elements, vitamins, minerals and survival factors naturally present in the yeast cell. The intake of micronutrients, vitamins and amino-acidic nitrogen is strategic in the early stages of yeast multiplication, when alcohol and oxygen deficiency have not yet changed the metabolism and the ability to consume nutrients. Due to Nutriferm Energy, the yeast cell increases the exponential growth rate, starting the fermentation phase first.
Technically this means:

• higher probability for the selected yeast to dominate fermentation
• lower production of undesired compounds (acetic acid, acetaldehyde, H2S)
• healthier yeast metabolism resulting in higher production of glycerol, polysaccharides and desirable
  aromas
• lower risk of stuck fermentations
• better control and management of fermentations

The positive effects of Nutriferm Energy are particularly evident in difficult conditions for yeast such as high sugar content must, botrytized grapes, strong microbiological contamination, etc.
