How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

50 guests × 75% drinking rate
= 38 drinkers

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

2

Calculate base consumption

38 drinkers × 1.5 drinks/hour × 4 hours
= 228 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)
= 185 adjusted drinks

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

4

Apply march madness party modifier

× 0.5 (-50% for wine)
= 91 wine servings needed

March Madness Partys typically consume 50% less wine than average.

5

Convert to bottles

91 servings ÷ 5 servings per bottle
= 18.2 bottles (raw)

Each bottle of wine provides 5 servings.

6

Add 15% buffer & round up

18.2 × 1.15 = 20.9, rounded up
= 21 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.

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.
