Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 40 guests × 75% drinking rate | 30 drinkers |
| Calculate base consumption | 30 drinkers × 1.5 drinks/hour × 3 hours | 135 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 119 adjusted drinks |
| Apply wedding shower modifier | × 0.5 (-50% for spirits) | 60 spirits servings if served alone |
| Share of the bar | 60 servings × 8.5% | 5 spirits servings |
| Convert to bottles | 5 servings ÷ 17 servings per bottle | 0.3 bottles (raw) |
| Add 15% buffer & round up | 0.3 × 1.15 = 0.3, rounded up | 1 bottle |
The Knot's wedding guide plans one drink per guest per hour with a 50/25/25 liquor, beer and wine split. This model counts only the guests who drink, slows the pace after the first hour, and keeps a 15 percent margin; read the methodology.
