Wyeast Wine Nutrient Blend is a custom blend of vitamins, minerals, and micronutrients essential for an orderly and complete fermentation.
During the cell growth and metabolization of sugars that takes place in every fermentation, yeast cells require an array of trace elements, vitamins, and compounds that can be assimilated from their environment in order to carry out their basic functions of life. However, honey-based fermentations are deficient in many of these nutrients. Nutrient deficiency can lead to disrupted or incomplete fermentations, off-flavors and aromas, and diminished stability of the finished product.
Supplementing your must with Wyeast Wine Nutrient Blend helps ensure high viability and health of your yeast population, which in turn helps ensure a rapid, complete, and successful fermentation with repeatable results.
Proprietary blend of vitamins, minerals, inorganic nitrogen, organic nitrogen, zinc, phosphates and other trace elements. Wyeast Nutrient Blend contains DAP (Diammonium Phosphate).
1/2 tsp (2.2 g) per 5 gallons (19 L) of must (unfermented mead)
Dissolve Wyeast Nutrient in warm water prior to adding to must. Divide total volume evenly, each portion to be added over several alternating days. Add to must after pitching yeast, and over the next several days as determined by your nutrient addition plan. Degassing between nutrient addition days may be necessary to prevent foaming over.
