You may be missing a digit, but if you went from 1.080 to 1.0
(assuming 1.000) then your ABV should be around 10.5%. Still assuming
you meant 1.000, then your ABV would be even higher than that since
you topped off with grape juice and then took the reading. I'm
guessing your reading before the addition was 0.990 with a .5 gallon
addition of 1.080 juice to bring it to 1.000 gravity in the end. That
would mean that before the addition, you were at 11.8%ABV.
