The Beverage Formula

Core Calculation

Drinks Needed = Guests × Drinks per Hour × Event Duration × Buffer

Standard Variables:

Drinks per hour: 1 drink per guest per hour (industry standard)
Buffer: 15% extra for safety
Wine serving: 5 glasses per 750ml bottle
Champagne serving: 6 flutes per 750ml bottle
Beer: 1 bottle/can per serving

First Hour Rule

Guests typically drink more in the first hour:

Hour 1: 1.5-2 drinks per guest
Hours 2-4: 0.75-1 drink per guest per hour

Plan accordingly for cocktail hour vs. dinner service.

Drinks Per Hour by Event Type

Event Type	Drinks/Hour	Notes
Wedding Reception	1.0	Standard pacing with food
Cocktail Party	1.2	Standing, social drinking
Dinner Party	0.9	Food slows consumption
Corporate Event	0.8	More restrained drinking
Casual Party	1.0	Relaxed atmosphere

Understanding Guest Preferences

Category	Percentage	Guests

Frequently Asked Questions

How many bottles of wine for 100 guests?

For 100 guests at a 4-hour event, plan for 40-50 bottles of wine (split between red and white). This assumes 50% of guests drink wine, consuming about 1 drink per hour, with a 15% buffer.

How much champagne do I need for a toast?

For a champagne toast, plan for 1 bottle per 6 guests. For 100 guests, you need 17-20 bottles of champagne. This provides one full flute per guest with buffer for spillage.

Is it better to buy too much wine?

Yes, slightly. Plan for 15% extra and check return policies. Running out of alcohol is a major party foul, while leftover unopened bottles can usually be returned or saved.

How do I account for non-drinkers?

Subtract 15-20% of your guest count as non-drinkers. Also provide quality non-alcoholic options (sparkling water, mocktails, soda) for designated drivers, pregnant guests, and those who don't drink.

Should I offer red and white wine?

Yes, always offer both. Standard split is 50/50, adjusted for:

Season (more white in summer)
Menu (more red with red meat)
Crowd preference
