How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

75 guests × 75% drinking rate

= 56 drinkers

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

Calculate base consumption

56 drinkers × 1.5 drinks/hour × 4 hours

= 336 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)

= 273 adjusted drinks

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

Apply halloween party modifier

× 0.4 (-60% for champagne)

= 110 champagne servings needed

Halloween Partys typically consume 60% less champagne than average.

Convert to bottles

110 servings ÷ 6 servings per bottle

= 18.3 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

18.3 × 1.15 = 21.0, rounded up

= 22 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.

Specialty cocktails with spooky names are a must - batch them ahead.

⏰

Dark spirits (whiskey, dark rum) fit the theme better than clear spirits.

🎯

Punch bowls with dry ice create amazing effects.

People in elaborate costumes drink slower - they don't want to spill.

✨

Adult-only parties consume 40% more than family Halloween events.

🛒 Buying Guide
