Planning your wedding bar is one of the most important parts of creating a seamless and fun guest experience—but one of the biggest questions couples ask is:

“How much alcohol do we actually need for our wedding?”

Order too little, and you risk running out mid-reception. Order too much, and you’re stuck overspending. At The Perfect Mix, we specialize in bar services for weddings in San Diego, Temecula, and all of Southern California, and we help couples confidently plan their alcohol quantities every single week.

This guide will break it down step-by-step so you know exactly what to buy.

The Golden Rule: Drinks Per Guest

The easiest way to estimate alcohol is by using this industry standard:

Plan for 2 drinks per guest for the first hour, and 1 drink per guest for each additional hour

Example:

For a 5-hour wedding with 100 guests:

First hour: 200 drinks
Remaining 4 hours: 400 drinks
Total: ~600 drinks

This gives you a solid baseline before breaking it into specific alcohol types.

How to Break Down Alcohol by Type

A well-balanced wedding bar typically follows this distribution:

50% Beer & Wine
30% Liquor (Cocktails)
20% Non-Alcoholic Beverages

From there, you can calculate how much of each category to purchase.

Wedding Alcohol Calculator (Simple Breakdown)

Here’s a practical shopping estimate for 100 guests / 5-hour reception:

🍷 Wine

1 bottle = ~5 glasses
Recommended: 20–25 bottles total
- 50% white
- 40% red
- 10% sparkling (for toasts)

🍺 Beer

Recommended: 90–120 beers
Offer 2–3 types:
- Light beer
- IPA or craft option
- Lager or domestic favorite

🍸 Liquor (for cocktails)

Assuming you’re offering 2–3 signature drinks:

1 bottle (750ml) = ~16 drinks
Recommended: 12–15 bottles total

Popular wedding bar selections:

Vodka
Tequila
Bourbon or whiskey
Gin (optional)

🥤 Non-Alcoholic Drinks

Plan for 1–2 drinks per guest per hour
Include:
- Water
- Soda
- Juice or mixers

Adjust Based on Your Wedding Style

Every wedding is different, and your alcohol needs can shift depending on your vibe and guest preferences.

1. Crowd Drinking Habits

Light drinkers: Reduce totals by ~10–15%
Heavy drinkers: Increase totals by ~10–20%

2. Signature Cocktails vs Full Bar

Signature Cocktail Menu

More predictable quantities
Easier to control costs
Faster service

Full Open Bar

More variety
Requires slightly more alcohol overall

3. Time of Day

Daytime weddings: Guests drink less
Evening weddings: Higher consumption
Hot weather (hello Temecula + San Diego): More refreshing drinks like spritzes and beer
