can someone portion this for me for a punch bowl? i am too dumb.

I don't think you are dumb. Does this make sense?
1.5 qt (6 cups or 48 oz.) bourbon -- this is 1420 ml so a little under 2 x 750 ml bottles
1.5 qt (6 cups or 48 oz.) juice
.75 qt (3 cups or 24 oz.) Domaine
1.5 qt (6 cups or 48 oz.) champagne - again approx 2 x 750 ml bottles

Total vol approx 5.25 qt = 21 x 8 oz. cups or 28 x 6 oz. cups

Gonna be some party!

and will you be using typical "punch cups" or another cup with ladle?

it belongs to colleague so not sure i think standard size. imagine punch for 25 maybe

How big is your punch bowl?
