Fermaid O is an organic version of Fermaid K. The organic nitrogen is a superior form, resulting in better results. Organic nitrogen provides a better fermentation with more stable temperatures.
Contains organic sources of nitrogen, not DAP, along with nutrients for a healthy fermentation with fewer heat spikes. Better yeast health equals better flavors. Use 1.5g per gallon. Rehydrate in distilled water and add at 1/3 sugar depletion.
