How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

125 guests × 70% drinking rate

= 88 drinkers

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

Calculate base consumption

88 drinkers × 1.5 drinks/hour × 4 hours

= 528 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)

= 429 adjusted drinks

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

Apply march madness party modifier

× 0.5 (-50% for wine)

= 213 wine servings needed

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

Convert to bottles

213 servings ÷ 5 servings per bottle

= 42.6 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

42.6 × 1.15 = 49.0, rounded up

= 49 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.
