Thanks for the great info. It is really helpful and encouraging to have experienced mazers answer these questions and allay our newbee fears
As for Fermaid-K and DAP, are these both really necessary? I ordered Go-Ferm and Fermaid-K for my next batch, but I could not find DAP on Austin Homebrew's site. I understand that Fermaid-K contains DAP, but is not specifically designed for the nutritional needs of mead must vs. wine must, hence the need for the extra DAP.
I have a 1.130 OG cyser fermenting right now with Wyeast Nutrient Blend (added 1/2tsp when I mixed it, another 1/2tsp today on day #3), and it seems to have a very healthy fermentation going.
I would assume that rehydrating the yeast with Go-Ferm and using Fermaid-K on the next batch will already give it a huge advantage, does extra DAP really help that much, or more of an insurance policy? Is the best (or most common) strategy to get the yeast to attenuate fully as fast as possible to reduce unwanted yeast by-products? (I guess fermenting hard and fast would also reduce the possibility of contamination and/or competing organisms, which is more difficult in the post-fermentation, alcoholic, liquid...)
Aren't there circumstances where we don't want the yeast to fully attenuate (i.e. D-47 overshooting its stated ABV tolerance and taking a planned semi-sweet mead totally dry), or does this just make things more complicated with the possibility of long-term, extended, fermentation and bottle bombs?
Sorry for the multiple questions, I really appreciate the advice/knowledge while I try to straighten all this out in my head :-D
