How Much Alcohol Do You Need for a Wedding Bar? (Complete Guide)

Planning your wedding bar can feel overwhelming, especially when trying to figure out how much alcohol to buy. The last thing you want is to run out mid-reception, or overspend on bottles you don’t need.

At Happy Trails Bar Co., we help couples across Los Angeles and Southern California plan perfectly balanced bar menus with just the right amount of alcohol.

The General Rule of Thumb

For most weddings, plan for:

  • 2 drinks per guest during the first hour

  • 1 drink per guest for each additional hour

So for a 100-guest, 4-hour wedding:
→ 500 drinks total

What Types of Alcohol Should You Buy?

A balanced bar typically includes:

  • Beer (light + IPA)

  • Wine (red + white)

  • 2–3 signature cocktails

  • Optional: champagne for toasts

Signature Cocktails Save You Money

Instead of a full open bar, many couples opt for 2 signature cocktails, which:

  • reduce liquor variety

  • speed up service

  • create a more curated experience

Don’t Forget Ice, Mixers & Garnish

This is where most DIY bars fall short. You’ll need:

  • Ice (a lot more than you think)

  • Citrus, syrups, soda, tonic

  • Cups or glassware

  • Garnishes
