How much spirits do I need for 30 guests?

You need 5 bottles of spirits for 30 guests at a corporate event. This provides 67 total servings with a 15% buffer to ensure you don't run out.

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.

How many servings are in a bottle of spirits?

One bottle of spirits contains 17 servings. For 30 guests, you'll need 5 bottles to provide 67 total servings.

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

At a corporate event with 30 guests, approximately 24 guests (80%) will actively drink. Our formula accounts for this when calculating the 5 bottles you need.

Should I buy extra spirits as a buffer?

Yes! Our calculation of 5 bottles already includes a 15% buffer (1 extra bottles). This ensures you won't run out even if some guests drink more than average. It's always better to have leftovers than to run short.

How long will 5 bottles of spirits last for 30 guests?

5 bottles of spirits will last approximately 3 hours for 30 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

30 guests × 80% drinking rate

= 24 drinkers

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

Calculate base consumption

24 drinkers × 1.5 drinks/hour × 3 hours

= 108 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)

= 95 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)

= 67 spirits servings needed

Corporate Events typically consume 30% less spirits than average.

Convert to bottles

67 servings ÷ 17 servings per bottle

= 3.9 bottles (raw)

Each bottle of spirits provides 17 servings.

Add 15% buffer & round up

3.9 × 1.15 = 4.5, rounded up

= 5 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.
