I just bottled my Cab Sauv. with the 1.5 L grape pack. Started it Dec. '09 with S.G. @ 1.086. Tastes pretty good, but not as oak-y as I expected, since I added two extra oak spirals (1 after 2nd racking, 2nd after 3rd racking).
Anyway, my question is what is the ABV? From the hyrdrometer reading it should be about 11.5-12%, but that must not account for the extra sugars in the grape pack, right? I mean, by definition, the grape-pack sugars that would raise the SG are not mixed into the must in the same way the sugars in the grape juice are.
So, is the ABV with grape pack kits actually higher than the initial hydrometer readings would lead us to believe? If so, how much higher (approximately, of course)?
This is more than academic as I would like to put the ABV on the label, so I am waiting to print my labels. Thanks,
