I am at the tail end of a fermentation with 5.5 gallons of cider with 4lbs of dark brown sugar in it. I was transferring to a clearing bottle yesterday and had a taste. It was good but very boozy. It needs to age a bit. I'll leave it in the 5gal better bottle a while longer hoping for some malolactic fermentation. Plus once this current batch of dark graff I'm doing is done I'll need more bottles. So the high ABV cider can continue to chill. I think it's going to be fantastic cider in a few months. My FG is coming in around 1.002ish so it's not totally dry and was still a bit sweet to taste. That could be some of non fermented sugars left behind in the dark brown sugar.
So here was my recipe. I did this in a 6 gallon ported better bottle.
5.5 gallons of fresh pressed cider (you're fine with AJ)
4lbs dark brown sugar
1.5lbs table sugar
a cup of chopped raisins
and WPL755 Cider Yeast (you could go with
