FERMENTATION NUTRIENTS & ADDITIVES
Nutrient additions to must support yeast (and bacteria) growth during fermentation while helping to avoid off aromas or flavors produced by nutrient deficient yeast populations. The ENOLAB’s juice analyses and juice panel tests for ammonia and amino acids to assess juice nutrient levels (reference Analytical Panels and Individual Analytical Analyses).
FERMAID K
A compounded formula that provides DAP, yeast hulls, vitamins and minerals.
2.5 kg – $60.37
10kg – $154.44
GO-FERM
Go-Ferm provides a source of yeast micronutrients that is added directly to the yeast rehydration water, and eliminates nutrient uptake by any microorganisms competing with the selected yeast. Go-Ferm can be used every time yeast is rehydrated and is especially recommended in high brix, high alcohol potential fermentations.
1 kg – $36.72
2.5 kg – $68.58
10 kg – $218.70
DIAMMONIUM PHOSPHATE (DAP)
DAP is added to juice/must to supplement natural levels of yeast assimilable nitrogen (YAN). Addition of DAP can stimulate yeast growth and fermentation activity and aids in prevention of the formation of hydrogen sulfide.
1 lb – $6.50
50 lb – $115.50
TARTARIC ACID
Tartaric acid is one of the main acids naturally found in grape juice, and is added during the winemaking process to reduce pH and increase the titratable acidity of a wine.
1 lb – $9.50
5 lb – $46.25
ACTI ML
Lallemand has developed a strain-specific nutrient for use with Enoferm Alpha. We still recommend the use of nutrients with direct-add bacteria only in high stress situations. These include stuck or sluggish MLF, or wine with more than two challenging conditions including pH less than 3.45, alcohol higher than 14.5%, total SO2 greater than 30 ppm or temperatures below 65F.
0.5 kg (for 660 gallons of wine) – $28.00
