i have approx. 8-12 lbs of elderberries that i picked and froze and am now cleaning off what stems i didn't get during harvest. my question is how important is it that i get all the tiny little pieces of stem off the berries? can i just get the huge stems and the majority of the little stems off and it will turn out or do i need to get every little stem piece? Also if after i cold soak, crush, and ferment then strain them how much weight of skins and such left will be sufficient to make another batch with some other fruit added?
