Wyeast Brewer's Choice Yeast Nutrient is a custom blend of vitamins, minerals, and micronutrients required for yeast cells to carry out an orderly and complete fermentation from start to finish. A wort that is nutrient-deficient, or which has adequate nutrients but limited bioavailability to the cells, can experience inhibited yeast growth, disrupted or incomplete fermentations, inconsistent attenuation rates from batch to batch, and diminished cell viability. Supplemental nutrients are always beneficial, but especially valuable during yeast propagation and stressful fermentation conditions (e.g, high-adjunct worts, high-gravity fermentations).
Contains: Proprietary blend of vitamins, minerals, inorganic nitrogen, organic nitrogen, zinc, phosphates and other trace elements.
Dosage rate: 11 grams/ barrel of wort
Usage: Dissolve in warm water. Add solution to kettle 10-15 minutes prior to end of boil.
