How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

125 guests × 70% drinking rate
= 88 drinkers

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

2

Calculate base consumption

88 drinkers × 1.5 drinks/hour × 3 hours
= 396 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)
= 350 adjusted drinks

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

4

Apply wedding shower modifier

× 1.8 (+80% for champagne)
= 626 champagne servings needed

Wedding Showers typically consume 80% more champagne than average.

5

Convert to bottles

626 servings ÷ 6 servings per bottle
= 104.3 bottles (raw)

Each bottle of champagne provides 6 servings.

6

Add 15% buffer & round up

104.3 × 1.15 = 119.9, rounded up
= 120 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 Wedding Shower

Insider advice from experienced bartenders

💡

Mimosa bars are the gold standard. Stock 1 bottle of sparkling per 3 guests, plus orange juice and peach nectar for variety.

⏰

Skip heavy reds. Go 70% white/rosé (Pinot Grigio, Sauvignon Blanc) and 30% light red (Pinot Noir).

🎯

Create one signature cocktail (Aperol Spritz, French 75) and batch it ahead of time - plan 2 servings per guest.

🧊

25-30% of guests won't drink alcohol. Offer elegant non-alcoholic options like mocktails or flavored sparkling water.

✨

Afternoon timing means lower consumption - most guests have 1-2 drinks max.

🛒 Buying Guide

For a 2-3 hour afternoon shower, plan for 1.3 drinks per guest. Champagne and wine dominate - stock 1 bottle of sparkling per 3 guests for mimosas, plus 1 wine bottle per 2 drinking guests. Buy 10-15% extra; unopened bottles can be returned or saved for the wedding. Prosecco is cost-effective for mimosas; save real Champagne for the toast.
