How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

75 guests × 75% drinking rate

= 56 drinkers

At medium events, about 75% of guests typically drink alcohol.

Calculate base consumption

56 drinkers × 1.5 drinks/hour × 4 hours

= 336 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)

= 273 adjusted drinks

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

Apply march madness party modifier

× 1.35 (+35% for beer)

= 370 beer servings needed

March Madness Partys typically consume 35% more beer than average.

Convert to cases

370 servings ÷ 24 servings per case

= 15.4 cases (raw)

Each case of beer provides 24 servings.

Add 15% buffer & round up

15.4 × 1.15 = 17.7, rounded up

= 18 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 March Madness Party

Insider advice from experienced bartenders

💡

Games run back-to-back during opening weekend - people may stay 6-8 hours.

⏰

Stock light beers for marathon watching sessions.

🎯

Multiple games mean multiple peaks - don't front-load everything.

🧊

Have non-alcoholic options for designated drivers and early bracket busts.

✨

Weekend games have 30% higher consumption than weekday games.

🛒 Buying Guide

March Madness parties are beer-heavy but lighter than Super Bowl (longer duration, people pace themselves). Stock 70% light beers. Have coolers at every TV location. Plan 4-5 beers per person for a 4-hour session.
