I assembled my first batch of Mead last Saturday 3/2 and fermentation has not begun yet 3/5 at 6am (must is at 68deg F). I am concerned and not sure the best approach to fixing at this point. Recipe used was 17lbs of Clover honey and 4gal water. Used White Labs WLP720 Sweet Mead/Wine Yeast, 2 tsp of Nutrient and 2 tsp of energizer. The recipe called for Lavlin D47 but I couldn't find it. Should I have not used the same energizer and nutrient with the liquid yeast? Suggestions on how to solve this issue?
