What a coincidence! I made this in the summer and just cracked the first bottle of it 3 days ago!
My recipe was a bit different.
1 gal batch
75% Apple juice
1.5 cups dextrose (i think, going from memory without my brew-book on hand)
1 can frozen apple juice concentrate for the back sweeten.
It ended at about the 6% mark, but I'm still a bit fuzzy on how percentages work when you back sweeten. It finished fermenting very dry, but with the back sweetening it has a very nice sharp flavour. VERY hard to put down.
I served it at my housewarming party on Saturday and it was a big hit. I only have one bottle left, but I am going to do a full batch over the holiday season.
Sounds like your in for a nice treat in the new year vvolf!
