How much wine per person for a corporate event?

Should I buy extra wine as a buffer?

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

100 guests × 70% drinking rate

= 70 drinkers

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

Calculate base consumption

70 drinkers × 1.5 drinks/hour × 3 hours

= 315 base drinks

Industry standard is 1.5 drinks per person per hour for a 3-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 2.65)

= 278 adjusted drinks

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

Apply corporate event modifier

× 1.1 (+10% for wine)

= 306 wine servings needed

Corporate Events typically consume 10% more wine than average.

Convert to bottles

306 servings ÷ 5 servings per bottle

= 61.2 bottles (raw)

Each bottle of wine provides 5 servings.

Add 15% buffer & round up

61.2 × 1.15 = 70.4, rounded up

= 71 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.
