I didnt know yeast could use supplements! Fermaid K contains some DAP, but for very low Nitrogen content must, DAP is recommended to bring YANC to above 150 mg N/L. The combination will increase the levels of those nutrients and boost the Yeast Assimilable Nitrogen (YAN), which will prevent the production off-flavors caused by sulfide compounds. Posted by 2 hours ago. Would be even better if the smaller quantities came in a resealable vial or bag. Proper use of Fermaid reduces the risk of sluggish or stuck fermentations. Overall excellent product. Great for starting fruit wines. Add to must at the beginning of fermentaion, and again at 1/3 sugar depletion for high nutrient requirement yeasts. 8. Basically yeast need a certain amount of YAN during fermentation. The available YAN in themust/juice directly impacts the fermentation rate and the formation of flavor-active volatilecompounds.
