How much champagne do I need for 150 guests?

You need 170 bottles of champagne for 150 guests at a wedding. This provides 886 total servings with a 15% buffer to ensure you don't run out.

How much champagne per person for a wedding?

Plan for 5.9 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.

How many servings are in a bottle of champagne?

One bottle of champagne contains 6 servings. For 150 guests, you'll need 170 bottles to provide 886 total servings.

What percentage of guests will drink champagne at a wedding?

At a wedding with 150 guests, approximately 105 guests (70%) will actively drink. Our formula accounts for this when calculating the 170 bottles you need.

Should I buy extra champagne as a buffer?

Yes! Our calculation of 170 bottles already includes a 15% buffer (22 extra bottles). This ensures you won't run out even if some guests drink more than average. It's always better to have leftovers than to run short.

How long will 170 bottles of champagne last for 150 guests?

170 bottles of champagne will last approximately 5 hours for 150 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

150 guests × 70% drinking rate

= 105 drinkers

At large events, about 70% of guests typically drink alcohol.

Calculate base consumption

105 drinkers × 1.5 drinks/hour × 5 hours

= 788 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)

= 591 adjusted drinks

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

Apply wedding modifier

× 1.5 (+50% for champagne)

= 886 champagne servings needed

Weddings typically consume 50% more champagne than average.

Convert to bottles

886 servings ÷ 6 servings per bottle

= 147.7 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

147.7 × 1.15 = 169.9, rounded up

= 170 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.
