How much champagne do I need for 75 guests?

How much champagne per person for a wedding?

Plan for 6.3 servings of champagne per person at a wedding. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

One bottle of champagne contains 6 servings. For 75 guests, you'll need 92 bottles to provide 475 total servings.

What percentage of guests will drink champagne at a wedding?

At a wedding with 75 guests, approximately 56 guests (75%) will actively drink. Our formula accounts for this when calculating the 92 bottles you need.

Should I buy extra champagne as a buffer?

How long will 92 bottles of champagne last for 75 guests?

92 bottles of champagne will last approximately 5 hours for 75 guests at a wedding. This calculation factors in the natural slowdown of consumption as the event progresses.

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

75 guests × 75% drinking rate

= 56 drinkers

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

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.

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.

Apply wedding modifier

× 1.5 (+50% for champagne)

= 475 champagne servings needed

Weddings typically consume 50% more champagne than average.

Convert to bottles

475 servings ÷ 6 servings per bottle

= 79.2 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

79.2 × 1.15 = 91.1, rounded up

= 92 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.

Pro Tips for Your Wedding

Insider advice from experienced bartenders

💡

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

⏰

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

🎯

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

🧊

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

✨

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

🛒 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.
