How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

75 guests × 75% drinking rate
= 56 drinkers

At medium events, about 75% of guests typically drink alcohol.

2

Calculate base consumption

56 drinkers × 1.5 drinks/hour × 5 hours
= 420 base drinks

Industry standard is 1.5 drinks per person per hour for a 5-hour event.

3

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.75)
= 315 adjusted drinks

People drink faster in the first hour and slow down as the event progresses.

4

Apply wedding modifier

× 1 (0% for spirits)
= 316 spirits servings needed

Weddings have standard spirits consumption.

5

Convert to bottles

316 servings ÷ 17 servings per bottle
= 18.6 bottles (raw)

Each bottle of spirits provides 17 servings.

6

Add 15% buffer & round up

18.6 × 1.15 = 21.4, rounded up
= 22 bottles

Always round up and add a buffer. Running out is worse than having leftovers!

Why trust this formula?

Based on industry standards and refined by bartenders with 30+ years of experience. We factor in consumption decay (people drink less as events progress) and real-world drinking percentages.

The Host's Secret

Editorial Curation

ATMOSPHERE

"40% of all alcohol is consumed during cocktail hour - front-load your bar staff and ice."

Pro Tip #1
PREPARATION

"Offer 1-2 signature cocktails instead of a full bar to cut spirit costs by 40% and speed up service."

Pro Tip #2
TIMING

"Pre-pour wine at dinner tables 5 minutes before guests sit to prevent service bottlenecks."

Pro Tip #3
SERVICE

"Order 10-15% extra and ask vendors about their return policy on unopened bottles."

Pro Tip #4
PRESENTATION

"If dancing goes past 10pm, reopen a simplified bar: beer, wine, and 2 signature drinks only."

Pro Tip #5

Buying Guide

For weddings, plan a 60/40 split between red and white wine for fall/winter, or flip it for spring/summer. Budget $12-18 per bottle for a crowd-pleasing selection - guests can't tell the difference between $15 and $40 wine at a party. Consider having champagne for toasts separate from your open bar calculation.
