How much spirits per person for a holiday party?

Plan for 3.9 servings of spirits per person at a holiday party. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

At a holiday party with 100 guests, approximately 70 guests (70%) will actively drink. Our formula accounts for this when calculating the 27 bottles you need.

Should I buy extra spirits 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 × 4 hours

= 420 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)

= 341 adjusted drinks

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

Apply holiday party modifier

× 1.15 (+15% for spirits)

= 392 spirits servings needed

Holiday Partys typically consume 15% more spirits than average.

Convert to bottles

392 servings ÷ 17 servings per bottle

= 23.1 bottles (raw)

Each bottle of spirits provides 17 servings.

Add 15% buffer & round up

23.1 × 1.15 = 26.6, rounded up

= 27 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.
