How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

10 guests × 80% drinking rate
= 8 drinkers

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

2

Calculate base consumption

8 drinkers × 1.5 drinks/hour × 4 hours
= 48 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)
= 39 adjusted drinks

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

4

Apply march madness party modifier

× 0.4 (-60% for champagne)
= 16 champagne servings needed

March Madness Partys typically consume 60% less champagne than average.

5

Convert to bottles

16 servings ÷ 6 servings per bottle
= 2.7 bottles (raw)

Each bottle of champagne provides 6 servings.

6

Add 15% buffer & round up

2.7 × 1.15 = 3.1, rounded up
= 4 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 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.
