How much champagne per person for a labor day party?

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

25 guests × 80% drinking rate

= 20 drinkers

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

Calculate base consumption

20 drinkers × 1.5 drinks/hour × 5 hours

= 150 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)

= 113 adjusted drinks

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

Apply labor day party modifier

× 0.5 (-50% for champagne)

= 56 champagne servings needed

Labor Day Partys typically consume 50% less champagne than average.

Convert to bottles

56 servings ÷ 6 servings per bottle

= 9.3 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

9.3 × 1.15 = 10.7, rounded up

= 11 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.
