Understandable, but wouldn't adding such a small quantity of juice make the dilution of alcohol negligible? I'm thinking a total of 16 oz of juice will be added to the end product of about 100 oz of hard cider.
Please correct me if I'm wrong, but wouldn't it go something like this:
OG = 1.055
FG(before sweetening and priming) = 1.005 <-- this is what I'm aiming for. Not actual numbers yet. Could be lower based on taste testing.
ABV = 6.56%
Add enough juice to accomplish desired sweetness levels. I'm thinking about 1.008.
Add the proper amount of juice that contains 1oz of sugar to prime my 1 gallon of hard cider. Approx 8oz. Bringing FG to about 1.011.
After the yeast gobbles up that priming sugar, I'll pasteurize, halting any more sugar consumption. Bringing the final FG back to approximately 1.008.
So true final numbers would be:
OG = 1.055
FG(after sweetening and carbonating) = 1.008
ABV = 6.17%
A difference of 0.39%.
EDIT: It's too early in the day for me for math stuffs.
I'd need to average out the two liquids to get my final ABV reading, right?
So 100oz of hard cider at 6.56% ABV, and 16oz of juice at 0.00% ABV.
Equation: (Volume1 X ABV1) + (Volume2 X ABV2) / (Volume1 + Volume2)
(100 x 0.0656) + (16 x 0.00) / 116 = 5.65%
A difference of 0.91%, which is a bit more, but still not a whole lot.
Yes, 16 oz should drop it by about .9%. That vs. about 4 oz of FAJC to achieve the same sugar level. And concentrate gives back more apple flavor to boot. But it's your call.
