How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

25 guests × 80% drinking rate
= 20 drinkers

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

2

Calculate base consumption

20 drinkers × 1.5 drinks/hour × 3 hours
= 90 base drinks

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

3

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 2.65)
= 80 adjusted drinks

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

4

Apply corporate event modifier

× 0.7 (-30% for spirits)
= 56 spirits servings needed

Corporate Events typically consume 30% less spirits than average.

5

Convert to bottles

56 servings ÷ 17 servings per bottle
= 3.3 bottles (raw)

Each bottle of spirits provides 17 servings.

6

Add 15% buffer & round up

3.3 × 1.15 = 3.8, rounded up
= 4 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.

Pro Tips for Your Corporate Event

Insider advice from experienced bartenders

💡

Most corporate guests self-limit to 2 drinks max - don't over-order.

Wine outsells beer 3:1 at corporate events - flip your usual ratio.

🎯

40% of corporate guests leave within 90 minutes - peak consumption is minutes 15-60.

🧊

Weekday events consume 35% less than Friday events.

Always have premium non-alcoholic options prominently displayed.

🛒 Buying Guide

Focus on quality over quantity for corporate events. Stock premium wines and craft options rather than bulk quantities. Have elegant non-alcoholic options visible - many professionals choose not to drink at work functions. A sophisticated sparkling water with citrus is always appreciated.
