How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

150 guests × 70% drinking rate

= 105 drinkers

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

Calculate base consumption

105 drinkers × 1.5 drinks/hour × 3 hours

= 473 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)

= 417 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)

= 292 spirits servings needed

Corporate Events typically consume 30% less spirits than average.

Convert to bottles

292 servings ÷ 17 servings per bottle

= 17.2 bottles (raw)

Each bottle of spirits provides 17 servings.

Add 15% buffer & round up

17.2 × 1.15 = 19.8, rounded up

= 20 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.
