The Math Behind 100 Wedding Guests

Wedding receptions typically run 4-6 hours with heavier drinking in the first 2 hours (cocktail hour and early reception). The standard formula is:

First hour: 2 drinks per person200 drinks
Hours 2-5: 1 drink per person per hour400 drinks
Total for 5-hour reception600 drinks

Here's how we split those 600 drinks:

Beer (30%):180 drinks = 10 cases (24-packs)
Wine (35%):210 drinks = 28 bottles (5 glasses per bottle)
Liquor (20%):120 drinks = 5 bottles (16-17 drinks per 750ml)
Champagne (15%):100 toast pours = 15 bottles (7 pours per bottle)

Frequently Asked Questions

How many bottles of wine for 100 wedding guests?

For 100 guests at a 5-hour wedding reception, plan for 25-30 bottles of wine. Each bottle serves about 5 glasses. Split roughly 60% white and 40% red for warm weather, or 50/50 for cooler seasons.

How many cases of beer for a 100 person wedding?

Plan for 8-10 cases of beer (24-packs) for 100 guests at a 5-hour reception. This assumes about 30% of drinks are beer. For a beer-loving crowd, increase to 12-14 cases.

How much champagne for 100 guests wedding toast?

For a champagne toast with 100 guests, you need 13-15 bottles. Each 750ml bottle pours about 7 flutes. Add 2-3 extra bottles as a buffer for spillage and seconds.
