How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

300 guests × 65% drinking rate

= 195 drinkers

At xlarge events, about 65% of guests typically drink alcohol.

Calculate base consumption

195 drinkers × 1.5 drinks/hour × 4 hours

= 1170 base drinks

Industry standard is 1.5 drinks per person per hour for a 4-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.25)

= 951 adjusted drinks

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

Apply holiday party modifier

× 1.4 (+40% for champagne)

= 1331 champagne servings needed

Holiday Partys typically consume 40% more champagne than average.

Convert to bottles

1331 servings ÷ 6 servings per bottle

= 221.8 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

221.8 × 1.15 = 255.1, rounded up

= 256 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.
