Complex Yeast Nutrients for Use during Fermentation

The original Nutrient is a blended complex yeast nutrient that supplies inorganic nitrogen (DAP), organic nitrogen (alpha amino nitrogen), key nutrients (magnesium sulfate, thiamine, folic acid, niacin, biotin and calcium pantothenate) and inactivated yeast. It is best to add nutrient over two additions. The first addition is made at the end of the lag phase (6 to 12 hours after yeast inoculation) and the second addition is made around 1/3 sugar depletion (the end of exponential growth and the beginning of the stationary phase). With proper rehydration and handling, the yeast cell population should be at least 4 million cells/mL at inoculation. By the time the second nutrient addition is made, this population should have grown to about 100 million cells/mL. It is critical to remember that yeast are still reproducing during the stationary phase, and to do this effectively, especially in high sugar musts, they need oxygen as well as nutrient, including nitrogen (for protein synthesis), sterols and fatty acids (for maintaining alcohol resistance and permease activity). In addition, the inactivated yeast cell walls adsorb medium-chain fatty acids that are toxic to yeast, and provide nucleation sites to help keep the yeast in suspension. Dosage recommendations: Add 12.5 g/hL (1 lb/1000 gal)at the end of the lag phase (beginning of alcoholic fermentation), and add 12.5 g/hL (1 lb/1000 gal) around 1/3 sugar depletion.
