Fermoplus DAP Free
Complex yeast nutrient free of DAP
Ideal Use: To keep higher alcohols and alcohol sensation low. For Organic wines.
Fermoplus DAP Free is a nutrient, suitable for organic wines, based on pure autolyzed yeast. This is not just heated live yeast that has been partially broken down, like products of this kind that have been seen in the past, but the pure extract coming from the autolysis of specific strains of yeast selected for their high content in amino acids, vitamins and Nitrogen. Autolyzed yeast provides all the nutritional elements that are needed in fermentation. Yeast extracts naturally provide YAN to the fermentation, however, if needed, winemakers may integrate this with additional DAP to complement the amount of amino Nitrogen available to the yeast. Also, toward the end of the fermentation it helps to minimize formation of fusel alcohols which may cause off flavors, sometimes described as “hot,” or “solvent-like.”
Utilization: Dissolve in must or wine and add to the tank. It is preferred to add Fermoplus DAP Free in three steps but it is most important at the beginning of the fermentation.
Dosage: Standard addition is 25-40 grams/Hl (2-3 pounds/1,000 Gallons). 12g/hL of Fermoplus DAP Free provides 9 ppm of YAN
Shelf life and storage: Fermoplus DAP Free is stable at room temperature for at least two years.
Packaging: 20 and 5kg bags
