Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 300 guests × 65% drinking rate | 195 drinkers |
| Calculate base consumption | 195 drinkers × 1.5 drinks/hour × 5 hours | 1463 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 1097 adjusted drinks |
| Apply Labor Day party modifier | × 1 (0% for spirits) | 1097 spirits servings if served alone |
| Share of the bar | 1097 servings × 30.4% | 333 spirits servings |
| Convert to bottles | 333 servings ÷ 17 servings per bottle | 19.6 bottles (raw) |
| Add 15% buffer & round up | 19.6 × 1.15 = 22.5, rounded up | 23 bottles |
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.
