How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

150 guests × 70% drinking rate

= 105 drinkers

At large events, about 70% of guests typically drink alcohol.

Calculate base consumption

105 drinkers × 1.5 drinks/hour × 4 hours

= 630 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)

= 512 adjusted drinks

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

Apply thanksgiving modifier

× 0.9 (-10% for champagne)

= 461 champagne servings needed

Thanksgivings typically consume 10% less champagne than average.

Convert to bottles

461 servings ÷ 6 servings per bottle

= 76.8 bottles (raw)

Each bottle of champagne provides 6 servings.

Add 15% buffer & round up

76.8 × 1.15 = 88.3, rounded up

= 89 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.
