Balanced Nutrition to Ensure a Healthy Fermentation of your Wine
It is not just about YAN! Understanding and using a balance between various amino acids and ammonia allows winemakers to improve the sensory profile of any wine, avoiding sluggish and stuck fermentations or sensory faults that will affect final quality.
Appropriate, balanced nutrition is essential to guarantee a complete and regular alcoholic fermentation. It ensures optimal biomass production, improves yeast composition and performance, and leads to a healthy fermentation process that produces desirable aromatic compounds and avoids the presence of off-flavors.
In winemaking, there is a mistaken belief that a higher dose of ammonia will help the development of yeast. Therefore, large quantities of diammonium phosphate (DAP) are added at yeast inoculation. At this stage, large additions of nitrogen can lead to overgrowth of yeast biomass, heat production, loss of volatile aromas and a sudden increase in fermentation speed with premature nitrogen depletion. This often affects yeast sugar metabolism and results in sluggish or stuck fermentations.
Current literature and internal trials have shown that equivalent biomass production is attained when correct, balanced nutrition is provided, regardless of the amount of YAN supplied. Yeast need nitrogen, amino acids, vitamins, microelements, sterols, fatty acids, and oxygen to produce biomass and maintain active metabolism.
By studying the nutritional needs of yeast, Enartis has developed the NUTRIFERM range of nutrients to provide the most important elements during each stage of fermentation. The combination of NUTRIFERM nutrients and the continuous monitoring of fermentation parameters with Winegrid sensors, both in tank and in barrel, allow to obtain a high quality wine.
- Improved sensory wine profile depending on the type of nutrition chosen
- Optimal status and biomass production leading to good yeast health and growth, preventing sluggish and stuck fermentations and the problems they create (off-flavors, re-starting alcoholic fermentation, labor, quality loss, etc.)
- Easy management, control and the possibility to take the necessary measures at the required time, even remotely.
- Adaptable to any winemaking protocol, technology, and type of wine.
- Sustainable technology due to better management of fermentation temperature

Products for a balanced nutrition and a healthy fermentation of your wine
NUTRIFERM ULTRA
NUTRIFERM ULTRA provides a source of essential and rapidly absorbed free amino acids, vitamins such as thiamine hydrochloride (vitamin B1), and minerals. Addition is recommended at the beginning of wine fermentation to stimulate yeast multiplication and reinforce yeast fermentation capacity. NUTRIFERM ULTRA helps shorten lag phase, prevents formation of H2S and acetic acid, and increases production of polysaccharides such as mannoproteins. It is designed to be added directly to juice with the yeast inoculation without prior dissolving (Easytech).

NUTRIFERM AROM PLUS
NUTRIFERM AROM PLUS consists of a specific autolyzed yeast with an elevated content of free aromatic amino acid precursors that yeast can use to promote the synthesis of secondary aromas such as esters. It significantly increases aromatic intensity and complexity of the wine. Due to its formulation, it can be added directly to juice with the yeast inoculation without prior dissolving (Easytech).

NUTRIFERM ADVANCE
NUTRIFERM ADVANCE provides DAP, inactivated yeast, and cellulose. It is formulated to keep yeast functional until complete sugar depletion by preventing irregular kinetics while maintaining efficient sugar transport. Furthermore, NUTRIFERM ADVANCE strengthens the cell walls of yeast and detoxifies the must.

NUTRIFERM NO STOP
NUTRIFERM NO STOP contains inactivated yeast rich in survival factors (sterols, long-chain fatty acids, etc.), and yeast hulls that help detoxify juice. It helps regenerate the yeast cell membrane and maintain its fluidity, preventing and correcting fermentation anomalies to ensure a successful alcoholic fermentation. Recommended in difficult conditions to prevent or treat sluggish and/or stuck fermentations, even at very low Brix levels.
