Yeastlife Extra helps brewers achieve fast, consistent fermentations while minimizing off flavors resulting from yeast stress.
The two main requirements for consistent, predictable fermentations are healthy yeast and a nutrient balanced wort.
Today it is commonly accepted that even wort produced from a well modified, all-malt grist still requires supplementation with oxygen and zinc to maintain optimal yeast health. Meanwhile worts produced via high gravity, adjunct brewing tend to show fermentation problems associated with nutrient deficiency and conditions of high stress for yeast.
Yeast generated under these difficult conditions typically show symptoms of reduced vigor, which can be compounded at each regeneration. These symptoms include slow or sticking fermentation, off-flavors associated with sulphur containing compounds, slow diacetyl reduction, and autolysis.
Yeastlife Extra yeast nutrient combats these issues by providing readily available sources of nitrogen blended with additional amino acids, minerals and vitamins.
