The right solution for neutral alcohol base production by fermentation.
SpringFermTM NAB-3 is a 100% mineral based fermentation aid developed by Fermentis to ferment pure-sugar media and high adjunct wort with yeast. It allows to ferment “pure” sugars very fast without any other additions and to obtain a perfectly neutral final product. This fermentation solution is ideal to produce neutral alcohol base for formulation into beverages such as alcopops, hard seltzers, …
Ingredients:
Minerals and Vitamins. See detailed composition on product label. All ingredients are food grade or pharmaceutical grade.
Dosage:
440g/hl for high gravity wort containing [270 – 300] g of “pure” sugar / liter.
Instructions of use:
Due to the neutrality target of the final product, focus should be on sterility throughout the process.
However, please note that sterilization or pasteurization could damage vitamins contained in SpringFermTM NAB-3.
First cool down sugar solution or very high adjunct wort to 30-35°C/86-95°F, then add SpringFerm ™ NAB-3. If possible, run agitation/recirculation for 10 minutes to ensure homogeneity, prior to yeast pitching.
Yeast should be either pitched directly in the fermentation vessel (if the yeast chosen is certified E2UTM) or rehydrated in a separate vessel. In this case, fill a vessel with 10x the weight of yeast in sterile water at 32-35°C/90-95°F. Add dry yeast to the vessel and let it rest for 10-15 minutes. After this waiting period, gently stir the solution to further rehydrate the dry yeast in water to make a cream solution. Wait an additional 10-15 minutes and the cream yeast is ready to pitch.
For the yeast strain chosen, please consult the TDS for fermentation temperature ranges.
