How this number is built
Total drinks = 150 guests × 5 hours × 1.0 drinks/hour × (1 − 0.15 non-drinkers) × 1.10 buffer = 701.2, so about 701 drinks. The full-bar split sends 35% to beer (246 units, bought as 11 cases of 24), 35% to wine (50 bottles at 5 glasses each) and 30% to spirits (13 bottles at ~17 drinks each). Champagne is separate: one toast glass for every guest, 25 bottles at 6 glasses each.
