How much champagne do I need for 15 guests?

You need 10 bottles of champagne for 15 guests at a corporate event. This provides 48 total servings with a 15% buffer to ensure you don't run out.

How much champagne per person for a corporate event?

Plan for 3.2 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.

How many servings are in a bottle of champagne?

One bottle of champagne contains 6 servings. For 15 guests, you'll need 10 bottles to provide 48 total servings.

What percentage of guests will drink champagne at a corporate event?

At a corporate event with 15 guests, approximately 12 guests (80%) will actively drink. Our formula accounts for this when calculating the 10 bottles you need.

Should I buy extra champagne as a buffer?

Yes! Our calculation of 10 bottles already includes a 15% buffer (2 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 10 bottles of champagne last for 15 guests?

10 bottles of champagne will last approximately 3 hours for 15 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

15 guests × 80% drinking rate

= 12 drinkers

At small events, about 80% of guests typically drink alcohol.

Calculate base consumption

12 drinkers × 1.5 drinks/hour × 3 hours

= 54 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)

= 48 adjusted drinks

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

Apply corporate event modifier

× 1 (0% for champagne)

= 48 champagne servings needed

Corporate Events have standard champagne consumption.

Convert to bottles

48 servings ÷ 6 servings per bottle

= 8 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

8 × 1.15 = 9.2, rounded up

= 10 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.
