How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

10 guests × 80% drinking rate
= 8 drinkers

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

2

Calculate base consumption

8 drinkers × 1.5 drinks/hour × 4 hours
= 48 base drinks

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

3

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.25)
= 39 adjusted drinks

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

4

Apply birthday party modifier

× 1.2 (+20% for champagne)
= 47 champagne servings needed

Birthday Partys typically consume 20% more champagne than average.

5

Convert to bottles

47 servings ÷ 6 servings per bottle
= 7.8 bottles (raw)

Each bottle of champagne provides 6 servings.

6

Add 15% buffer & round up

7.8 × 1.15 = 9.0, rounded up
= 10 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.

Pro Tips for Your Birthday Party

Insider advice from experienced bartenders

💡

Milestone birthdays (21st, 30th, 40th, 50th) consume 25% more than regular birthdays.

⏰

Birthday parties have 3x more shots than any other event type - stock shooters.

🎯

Consumption drops 60% during cake and presents - factor in 30-45 min of low drinking.

🧊

Know your crowd's age - 21-30 year olds drink 30% more beer, 50+ drink 35% more wine.

✨

Consider a signature 'birthday cocktail' to make the guest of honor feel special.

🛒 Buying Guide

Birthday parties vary wildly by age group. For 21-35, stock up on beer and mixers for cocktails. For 40+, increase your wine selection. Always have extra for milestone birthdays - people celebrate harder at 30, 40, and 50.
