How We Calculated This
Our bartender-tested formula, step by step
Estimate actual drinkers
At large events, about 70% of guests typically drink alcohol.
Calculate base consumption
Industry standard is 1.5 drinks per person per hour for a 5-hour event.
Apply consumption decay
People drink faster in the first hour and slow down as the event progresses.
Apply wedding modifier
Weddings typically consume 50% more champagne than average.
Convert to bottles
Each bottle of champagne provides 6 servings.
Add 15% buffer & round up
Always round up and add a buffer. Running out is worse than having leftovers!
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.

The Host's Secret
Editorial Curation
"40% of all alcohol is consumed during cocktail hour - front-load your bar staff and ice."
"Offer 1-2 signature cocktails instead of a full bar to cut spirit costs by 40% and speed up service."
"Pre-pour wine at dinner tables 5 minutes before guests sit to prevent service bottlenecks."
"Order 10-15% extra and ask vendors about their return policy on unopened bottles."
"If dancing goes past 10pm, reopen a simplified bar: beer, wine, and 2 signature drinks only."
Buying Guide
For weddings, plan a 60/40 split between red and white wine for fall/winter, or flip it for spring/summer. Budget $12-18 per bottle for a crowd-pleasing selection - guests can't tell the difference between $15 and $40 wine at a party. Consider having champagne for toasts separate from your open bar calculation.
