How much champagne do I need for 20 guests?

You need 14 bottles of champagne for 20 guests at a thanksgiving. This provides 70 total servings with a 15% buffer to ensure you don't run out.

How much champagne per person for a thanksgiving?

Plan for 3.5 servings of champagne per person at a thanksgiving. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

How many servings are in a bottle of champagne?

One bottle of champagne contains 6 servings. For 20 guests, you'll need 14 bottles to provide 70 total servings.

What percentage of guests will drink champagne at a thanksgiving?

At a thanksgiving with 20 guests, approximately 16 guests (80%) will actively drink. Our formula accounts for this when calculating the 14 bottles you need.

Should I buy extra champagne as a buffer?

Yes! Our calculation of 14 bottles already includes a 15% buffer (2 extra bottles). This ensures you won't run out even if some guests drink more than average. It's always better to have leftovers than to run short.

How long will 14 bottles of champagne last for 20 guests?

14 bottles of champagne will last approximately 4 hours for 20 guests at a thanksgiving. This calculation factors in the natural slowdown of consumption as the event progresses.

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

20 guests × 80% drinking rate

= 16 drinkers

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

Calculate base consumption

16 drinkers × 1.5 drinks/hour × 4 hours

= 96 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)

= 78 adjusted drinks

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

Apply thanksgiving modifier

× 0.9 (-10% for champagne)

= 70 champagne servings needed

Thanksgivings typically consume 10% less champagne than average.

Convert to bottles

70 servings ÷ 6 servings per bottle

= 11.7 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

11.7 × 1.15 = 13.5, rounded up

= 14 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 Thanksgiving

Insider advice from experienced bartenders

💡

Wine consumption peaks during dinner - have bottles ready at the table.

⏰

Pre-dinner cocktails should be light so people can enjoy the meal.

🎯

After-dinner drinks (port, brandy) are a nice touch.

🧊

Football watching = beer in the afternoon before dinner.

✨

Designated drivers are essential - plan non-alcoholic options.

🛒 Buying Guide

Thanksgiving is wine-heavy with the meal. Plan 1 bottle of wine per 2 adults at the table. Have a light cocktail option for pre-dinner and maybe some beer for football watching. Keep it classy.
