The banquet is over, the nerves of the ceremony have faded, and the moment most guests have been waiting for arrives: the party. This is when the wedding open bar becomes the engine of the celebration, the fuel that keeps the dance floor full and the energy sky-high. Managing it, though, is not just a matter of "pouring drinks" — it takes planning to keep the budget in check and the service moving quickly.
From working out how many bottles you'll need to deciding between top-tier brands or a more standard option, the questions are endless. Is it better to book by the hour or by consumption? What does a wedding's open bar cost in 2024? Below, we break down everything you need to know to organize this essential service, and how to pair it with the best entertainment ideas to make your party legendary.
What is a wedding open bar?
A wedding open bar is a hospitality service that lets guests drink (alcoholic and non-alcoholic beverages) without limit for a set period of time, without paying for each drink individually. It's the standard format in Spain for the party following the reception, so guests have nothing to worry about but having a good time.
Types and formats of open bar
There's no single format for the party. The type of service you choose depends on the budget you want to set aside, the profile of your guests, and how much you want to personalize the event. Venues and catering companies usually offer different tiers to suit each need:
Standard vs. high-end open bar
The standard option includes the most common, commercial spirit brands. If you want to elevate the experience, the high-end tier offers more prestigious labels — craft gins, single-malt whiskies, aged rums — which raises the cost of the open bar but satisfies more demanding palates.
Themed corners and cocktail bars
A growing trend is setting up specialized bars — from a mojito and caipirinha corner to a "gin bar" with botanicals and specialty tonics. This doesn't just serve drinks; it adds a striking visual element to the wedding's open bar décor.
Alcohol-free open bar (mocktails)
With every guest in mind, it's increasingly common to offer a mocktail menu — alcohol-free cocktails made with fresh fruit and syrups — going well beyond simple soft drinks.
What does a wedding's open bar include?
When booking this service, you're not just paying for the alcohol. A complete, professional quote should account for all the logistics needed to keep the service smooth and elegant:
Staff and service (bartenders)
The usual ratio is one bartender for every 30-40 guests. This is essential to avoid lines at the bar that cool down the party.
Glassware, tableware, and ice
This covers balloon glasses, highball glasses, shot glasses, and the ice needed — good-quality ice — for the whole night. Nothing ruins a drink faster than ice that melts in seconds.
Mixers, soft drinks, and garnishes
Spirits don't stand alone. The service includes all soft drinks, tonics, and juices, as well as the fruit and garnishes for every drink.
What does an open bar cost at a wedding?
Knowing how much a wedding's open bar costs is one of the biggest concerns when finalizing the budget. Prices vary depending on location, caterer, and brand quality, but there are two main pricing models:
The most common format is price per guest, per hour. Venues or caterers generally include the first few hours (usually 3 or 4) in the menu price, or charge a flat fee between €12 and €25 per guest for that initial period. Extra open bar hours are usually billed separately, at around €300–€500 per additional hour for the whole group, or a reduced per-guest rate.
Another option is pay-per-consumption (bottles opened), though it's less common at large weddings since it makes the final spend harder to control. Always ask whether VAT on the open bar is included in the initial quote.
Is an open bar worth it at a wedding?
Absolutely. Compared with ticket systems or pay-per-drink, an open bar gives the couple peace of mind and guests comfort. It removes the need for guests to carry cash and keeps the service moving. It's also, together with the music during the open bar, one of the elements that keeps the fun going — without it, the party tends to wind down much faster.
How to calculate the ideal open bar for your guest count. Step by step
If you decide to organize the wedding's open bar yourselves (buying the bottles directly) or need to double-check the caterer's numbers, here's a rough formula to avoid running short or overspending:
1. The bottle-count rule
A standard 70cl bottle yields around 12-14 drinks. Average consumption is usually set at about 3 or 4 drinks per person (accounting for guests who won't drink and others who'll drink more). A simple rule is to divide the number of drinking guests by 3 to get the number of spirit bottles you'll need.
2. Drink proportions
Not everything gets drunk equally. A standard breakdown for wedding open bars in Spain tends to be: 40% gin, 30% rum, 20% whisky, and 10% vodka. That said, it depends heavily on the age and taste of your guests.
3. Soft drinks and ice
Plan on about 3 or 4 soft drinks per bottle of spirits if serving in highball glasses, or 2-3 if using balloon glasses with plenty of ice. And speaking of ice: always plan for more than you think you'll need — roughly 1kg of ice per person for a 4-hour open bar.
What can you pair with the open bar to create a complete experience at your wedding?
The drinks matter, but real fun happens when you pair them with interactive entertainment. If you're looking for things to do at a wedding to surprise your guests during the party, there are elements that make all the difference and keep people from just drinking alone in a corner.
A leading trend is pairing the drinks with a wedding tattoo bar (temporary or henna tattoos) or glitter make-up stations. But if you want the fun to go viral, technology is your best ally. Setting up a 360 Video station near the dance floor lets guests film spectacular slow-motion videos, drink in hand, creating instant content for social media.
In the same way, a portrait station for events acts as the perfect gathering point. While they queue for their printed photo, guests socialize and laugh, keeping the party's energy up. And for a red-carpet touch, nothing beats the Glambot, capturing the elegance of your guests — and their toasts — with cinematic quality.
