SIY 33™ is a pure, autolyzed, spray dried yeast. It provides natural alpha amino nitrogen, B vitamins and yeast hulls. SIY 33 will help supplement the alpha amino nitrogen component of YAN. Add at 1/3 sugar depletion when inorganic nitrogen is NOT desired.
Unlike Fermaid K, SIY 33 does not contain added ammonia salts (DAP) or supplemented micronutrients.
In order to avoid CO2 release and overflowing of fermentation vessels, SIY 33 should be mixed with room temperature water before adding to an active fermentation. The amount of water used is not critical. Simply add enough water to make a slurry.
Dated expiration. Store in a cool and dry environment at 18°C(65°F). Once opened, keep tightly sealed and dry.
