One of the first decisions every party host faces is what kind of bar to offer. It affects your budget, logistics, bartending needs, and the entire vibe of the event. There is no single right answer β it depends on your occasion, crowd, venue, and budget.
This guide walks through the four main bar types, when each one makes sense, what each costs, and how to plan quantities for whichever you choose.
Beer & Wine Only β The simpler, more affordable choice. Works for most casual and semi-formal occasions, daytime events, and any situation where you're serving without a professional bartender.
Full Open Bar β Spirits, wine, beer, and mixers. Expected at formal events; highest cost and complexity. Requires a bartender for groups over 40β50 guests.
Signature Cocktail Bar β One or two pre-batched craft cocktails plus beer and wine. Elevated feel with controlled complexity and cost. The increasingly popular middle ground.
Bubbles & Wine β Sparkling wine, rosΓ©, and still wines. Ideal for daytime events, brunches, and bridal showers.
For most backyard parties, casual celebrations, showers, and informal corporate events, beer and wine is the right call. The key is doing it well: two or three wines, four to six beer options including at least one craft, and something non-alcoholic that feels intentional.
| Guests | Event Length | Wine (bottles) | Beer (cases) |
|---|---|---|---|
| 30 | 3 hours | 8β10 | 1β2 |
| 50 | 4 hours | 16β20 | 2β3 |
| 75 | 4 hours | 24β30 | 3β4 |
| 100 | 5 hours | 35β42 | 5β6 |
A full open bar is what guests expect at formal weddings, upscale corporate events, milestone birthdays, and gala-style receptions. It is the most expensive and logistically complex option, but it delivers the most festive atmosphere and maximum guest choice.
The core spirits for any full bar: vodka, bourbon or American whiskey, gin, tequila, rum, and optionally scotch. Mixers are non-negotiable: club soda, tonic, cola, ginger ale, cranberry juice, orange juice, simple syrup, and fresh citrus.
One or two pre-batched signature cocktails alongside beer and wine, without a full spirit lineup. You get the visual impact of craft cocktails, the simplicity of a limited bar, and a manageable budget. A couple's signature cocktail at a wedding β a custom Paloma, a themed rum punch β is also a great conversation piece tied to the event's theme.
How to make it work: choose one spirit, build your cocktail around it, batch it in advance, and serve alongside beer and wine. Label it clearly with the cocktail name and ingredients for allergy awareness.
Champagne or prosecco, rosΓ©, and one or two still wines β nothing else. Works beautifully for daytime receptions, bridal showers, garden parties, and afternoon celebrations. Feels luxurious and intentional without being complicated.
| Bar Type | Approx. Cost Per Guest |
|---|---|
| Beer & Wine | $8β$18 |
| Signature Cocktail + Beer & Wine | $12β$22 |
| Bubbles & Wine | $15β$30 |
| Full Open Bar | $25β$55 (includes bartender) |
