How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

50 guests × 75% drinking rate
= 38 drinkers

At medium events, about 75% of guests typically drink alcohol.

2

Calculate base consumption

38 drinkers × 1.5 drinks/hour × 5 hours
= 285 base drinks

Industry standard is 1.5 drinks per person per hour for a 5-hour event.

3

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.75)
= 214 adjusted drinks

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

4

Apply 4th of july party modifier

× 0.5 (-50% for champagne)
= 105 champagne servings needed

4th of July Partys typically consume 50% less champagne than average.

5

Convert to bottles

105 servings ÷ 6 servings per bottle
= 17.5 bottles (raw)

Each bottle of champagne provides 6 servings.

6

Add 15% buffer & round up

17.5 × 1.15 = 20.1, rounded up
= 21 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.
