Last night I threw together a new batch of my own variation of the No-Age Mead, and have a question about nutrients. I have the "Yeast Nutrient" from LD Carlson, which is basically DAP and Urea. I've been reading up that Urea is not highly suggested for mead, but that was after adding 3 tsp to the mix pre pitch. I rehydrated the 71-B per instructions, and pitched last night at about 9pm. As of this morning (9am), there appears to be no activity. SG is the exact same.
I hear that 71-B is a nutrient hog, and herein lies the problem. None of my LHBS carry Fermaid and straight DAP. Since this is already pitched, I cannot wait the 4 days for delivery from an online site. Would I be OK tossing in some raisins and some nutritional yeast (Red Star http://lesaffre-yeast.com).
Another thing I need to check is that the room I stored it in last night was a nice brisk 64F, and I see that is the lower limit of the 71-B. I moved it into the main living area which is a stead 70F. Hopefully that will help it move, but just in case are these two additions safe to add?
