How much champagne per person for a new year's eve party?

Plan for 9 servings of champagne per person at a new year's eve party. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

15 guests × 80% drinking rate

= 12 drinkers

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

Calculate base consumption

12 drinkers × 1.5 drinks/hour × 5 hours

= 90 base drinks

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

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.75)

= 68 adjusted drinks

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

Apply new year's eve party modifier

× 2 (+100% for champagne)

= 135 champagne servings needed

New Year's Eve Partys typically consume 100% more champagne than average.

Convert to bottles

135 servings ÷ 6 servings per bottle

= 22.5 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

22.5 × 1.15 = 25.9, rounded up

= 26 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 New Year's Eve Party

Insider advice from experienced bartenders

💡

70% of champagne is consumed between 11:30pm and 12:15am - time your chilling.

⏰

Have champagne COLD and ready to pour at 11:55pm.

🎯

People pace themselves until 10pm then drinking accelerates.

🧊

Late-night parties need designated drivers or Uber - plan ahead.

✨

Noisemakers and party favors should be near the champagne station.

🛒 Buying Guide

This is THE champagne event. Plan 1 bottle per 3-4 guests for the midnight toast, plus additional for cocktails (French 75s, Kir Royale). Have regular bar options for earlier in the evening. Stock more than you think - better to have leftovers than run out at midnight.
