Hey all, has anyone tried the "new" Fermaid O or NATSTEP (Fortiferm or Enoferm) for their mead(s)? Just wondering if there is any history/experience with these versus Fermaid K.
Per Lallemand web site; "Fermaid O does not contain added ammonia salts (DAP) or micronutrients. The importance of organic nitrogen from yeasts is well known as a highly efficient nutrient source for wine yeasts, especially when compared to inorganic nitrogen from DAP. In addition, Fermaid O consistently produces lower levels of negative sulfur compounds, compared with DAP. With its high content of organic nitrogen, Fermaid O can help winemakers achieve steady fermentations, while limiting temperature peaks. When inorganic nitrogen (DAP) additions are NOT desired, the use of Go-Ferm® or NATSTEP™ and Fermaid O is recommended. With this combination, Go-Ferm or NATSTEP provides needed micronutrients during yeast rehydration, and Fermaid O (when added at 1/3 sugar depletion) supplies critical nutrients and survival factors to help the yeast avoid stressed conditions."
