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 × 4 hours

= 630 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)

= 512 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)

= 717 champagne servings needed

Holiday Partys typically consume 40% more champagne than average.

Convert to bottles

717 servings ÷ 6 servings per bottle

= 119.5 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

119.5 × 1.15 = 137.4, rounded up

= 138 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.
