Research involving wine quality and fermentation kinetics over the last few years has changed the focus on nutrition from using a purely mineral source to an emphasis on the importance of including an organic, amino nitrogen source in any yeast nutrition regimen.

ATP's fully TTB & export authorized nutrient Bioferm is 100% organic, rich in amino acids and naturally occurring vitamins and minerals.  The completely yeast derived highly soluble amino acids in Bioferm provide both immediate and long term nutrition, minimizing the risks of H₂S, VA and stuck/sluggish fermentations.  

Because Bioferm is a pure product and free of fillers it is an exceptional value, especially on a per dose basis.  When used in conjunction with DAP it allows winemakers to take advantage of the positive aspects of both organic amino nitrogen and mineral nitrogen.  Since many blended 'complex' nutrients derive 85% or more of their total YAN value from DAP using Bioferm plus DAP also represents an overall nutrient cost savings of 50% or more versus the blended products.

As a result of the performance and cost benefits using Bioferm at a rate of 1.5 - 2 #/1000 gallons and achieving YAN targets by supplementing with DAP has become a foundation of many of our clients' yeast nutrition regimens.  If you have any questions or would like some industry references please let us know, or CLICK HERE to read more.
