Calculating ABV of Blend

[OBSCZONER]

Hey guys, I am going to be doing alot of blending soon. Have a Kriek and a Blackberry Lambic. Going to blend young lambic for carbonation.

Also going to blend the two together for a mashed up fruit lambic, kind of like Cantillon Rose. and eventually I will be blending a "Gueuze"

Just curious how I would go about calculating the ABV%. Any help i appreciated

Take the ABV of Beer1 (ABV_1) and multiply it by the percent it represents of the total blend (%_1). Do this for each part, sum them up.

(ABV_1*%_1)+(ABV_2*%_2)+(ABV_3*%_3) = Final ABV
