Alcohol adding math help needed

westchesterBrewer · May 8, 2014

I'm making a 5 gallon bourbon barrel porter batch. The beer itself is 7% ABV. THe recipe calls for adding 16 oz of bourbon. My bourbon is 50% abv. What will the final abv be when everything is combined?

5 gal X 128 oz/gal = 640 oz. total
640 oz X .07 = 44.8 oz. alcohol
add
16 oz burbon = 656 oz. total
8 oz alcohol in burbon = 52.8 oz. alcohol

52.8/656 * 100 = 8.05% abv
