How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

300 guests × 65% drinking rate
= 195 drinkers

At xlarge events, about 65% of guests typically drink alcohol.

2

Calculate base consumption

195 drinkers × 1.5 drinks/hour × 4 hours
= 1170 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)
= 951 adjusted drinks

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

4

Apply thanksgiving modifier

× 0.8 (-20% for beer)
= 761 beer servings needed

Thanksgivings typically consume 20% less beer than average.

5

Convert to cases

761 servings ÷ 24 servings per case
= 31.7 cases (raw)

Each case of beer provides 24 servings.

6

Add 15% buffer & round up

31.7 × 1.15 = 36.5, rounded up
= 37 cases

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.
