How much champagne do I need for 150 guests?

How much champagne per person for a corporate event?

Plan for 2.8 servings of champagne per person at a corporate event. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

At a corporate event with 150 guests, approximately 105 guests (70%) will actively drink. Our formula accounts for this when calculating the 80 bottles you need.

Should I buy extra champagne as a buffer?

80 bottles of champagne will last approximately 3 hours for 150 guests at a corporate event. 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 × 3 hours

= 473 base drinks

Industry standard is 1.5 drinks per person per hour for a 3-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 2.65)

= 417 adjusted drinks

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

Apply corporate event modifier

× 1 (0% for champagne)

= 417 champagne servings needed

Corporate Events have standard champagne consumption.

Convert to bottles

417 servings ÷ 6 servings per bottle

= 69.5 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

69.5 × 1.15 = 79.9, rounded up

= 80 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.
