This is an excellently educational thread. Thanks to everyone who contributed!
It brings up something I was wondering. I'm doing my first batch now. About a week ago my fermentation finished (FG 0.996 for 72hrs) and I racked it from my plastic fermenter to a carboy to get it off the lees. Since then more lees have settled out, but the mead is still very cloudy to the point of being opaque. My plan going forward is to age the mead in bulk in the carboy for at least 6 months.
I'm thinking I'll probably have to rack again at some point in the next week or two to get the mead off the new lees that are forming? I don't want them to start autolysing and make my mead taste yeasty.
My main question is this: is it better to stabilize, back-sweeten, adjust acidity, and clarify now at the beginning of aging--the thought being to let the flavors marry and gain complexity during that time--or to do all that at the end of the bulk aging prior to bottling?
