Vintners Complete is a complete yeast nutrient. By stimulating yeast growth and survival, it can significantly reduce stuck fermentations. Research reveals that the best yeast food is not a single nitrogen source, but a combination of ingredients. Vintner's Complete contains yeast hulls, yeast extracts, vitamins, and minerals.
The yeast hulls provide sterols and survival factors and adsorb toxic fatty acids, particularly decanoic acid, which tend to inhibit yeast growth. Diammonium phosphate is a basic nitrogen source and helps prevent Hydrogen Sulfide production.
Yeast extracts contain amino acids, making them a rich food source, and vitamins and minerals, which are essential to vigorous yeast growth. Together these ingredients create an excellent, balanced nutrient for yeast.
Vintner Complete is recommended for both grape and non-grape musts, cider and beer. It is especially useful for musts that have a history of sluggish fermentation or Hydrogen Sulfide production. Vintne
