Thus, at most adding a handful of raisins to your batch of mead will give you perhaps one-tenth of the required nutrients needed for healthy yeast fermentation. Yeast Energizer is also ideally suited for re-starting a stuck fermentation. Nitrogen can be purchased in the form of diammonium phosphate (DAP), which not only provides the nitrogen, but also phosphorus that the yeast utilizes. The presence of nutrients throughout the entire fermentation process is important, even after growth has concluded. Honey especially lacks a source of nitrogen.
