How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

150 guests × 70% drinking rate
= 105 drinkers

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

2

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.

3

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.

4

Apply thanksgiving modifier

× 0.8 (-20% for beer)
= 410 beer servings needed

Thanksgivings typically consume 20% less beer than average.

5

Convert to cases

410 servings ÷ 24 servings per case
= 17.1 cases (raw)

Each case of beer provides 24 servings.

6

Add 15% buffer & round up

17.1 × 1.15 = 19.7, rounded up
= 20 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.

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.
