Anyway, I recently made a bourbon porter similar to the popular vanilla bourbon porter recipe floating around, and I wanted to correctly calculate the ABV after my bourbon addition.

If I have 5 gallons of porter @ 6.7% ABV and add 10oz of bourbon at 45% abv, how many points does that raise the 5 gallons? What is the formula to calculate this?
