making a blueberry mead. 10 lbs honey, 5 lbs blueberries, 4 gallons water... 2 sachets lalvin 76b-1122 yeast.
fermented one month...
my final grav was 1.01.
im supposed to add 5 lbs of honey and 5 lbs blueberry and go another month or two.
i racked it off the crud to a clean/sanitized fermenter... added the stuff and topped off with an additional gallon. (still have a little headspace).
will i have enough yeast since i racked to complete the process? or do i need to make a starter with anther pack and add that to it?
how much headspace is bad?
