How much spirits per person for a corporate event?

Plan for 2.2 servings of spirits per person at a corporate event. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

What percentage of guests will drink spirits at a corporate event?

At a corporate event with 15 guests, approximately 12 guests (80%) will actively drink. Our formula accounts for this when calculating the 3 bottles you need.

Should I buy extra spirits as a buffer?

How long will 3 bottles of spirits last for 15 guests?

3 bottles of spirits will last approximately 3 hours for 15 guests at a corporate event. This calculation factors in the natural slowdown of consumption as the event progresses.

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

15 guests × 80% drinking rate

= 12 drinkers

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

Calculate base consumption

12 drinkers × 1.5 drinks/hour × 3 hours

= 54 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)

= 48 adjusted drinks

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

Apply corporate event modifier

× 0.7 (-30% for spirits)

= 33 spirits servings needed

Corporate Events typically consume 30% less spirits than average.

Convert to bottles

33 servings ÷ 17 servings per bottle

= 1.9 bottles (raw)

Each bottle of spirits provides 17 servings.

Add 15% buffer & round up

1.9 × 1.15 = 2.2, rounded up

= 3 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.
