How Much Is an Open Bar at a Wedding?

There isn't one fixed price because the cost depends on the number of guests, how long the bar is open, which drinks you want to serve, your venue and how much your guests are likely to drink. An open bar can be excellent value for a larger wedding, but a smaller guest list or a particularly premium drinks menu can make the cost per person considerably higher.

What Is an Open Bar at a Wedding?

An open bar is a wedding bar where guests can order drinks without paying for each drink themselves. Instead, the couple or whoever is organising the wedding covers the cost of the drinks.

Depending on the arrangement, an open bar might include cocktails, wine, beer, spirits and soft drinks, or it might focus on a more specific selection.

Some couples choose to offer an open bar throughout the reception, while others provide it for a set period, such as during the wedding breakfast and evening reception.

What Affects the Cost of a Wedding Open Bar?

There are several factors that determine the overall cost of an open bar.

Number of Guests

Guest numbers are one of the biggest considerations.

It might seem obvious that a smaller wedding should always cost less, but that's not necessarily how mobile bar services work. There are fixed costs involved in bringing a professional bar to a venue, including equipment, transport, setup and staffing.

This means that serving a relatively small number of guests can result in a much higher cost per person.

Larger weddings can often benefit from economies of scale because the fixed costs are spread across more guests and more drinks.

How Long the Bar Is Open

The length of service also affects the cost.

A bar serving drinks for an hour during the reception requires a very different setup from a bar operating throughout a six-hour wedding celebration.

Longer service may require additional staff, more drinks and greater quantities of ice, mixers and other ingredients.

Which Drinks Are Included?

Your drinks menu can make a significant difference.

A simple selection of beer, wine and soft drinks will have different costs from an open bar featuring premium spirits, champagne and freshly made cocktails.

Cocktails can also vary considerably depending on the ingredients and preparation involved. A simple two- or three-ingredient cocktail menu is very different from a menu featuring elaborate cocktails with fresh fruit, homemade ingredients and premium spirits.

How Much Is an Open Bar at a Wedding? It Depends on Consumption

When couples ask How Much Is an Open Bar at a Wedding?, one of the most important things to consider is how many drinks your guests are likely to have.

There is no universal number of drinks that every wedding guest will consume. Some guests may drink throughout the evening, while others might have only a couple of drinks.

The time of day, type of wedding, guest demographics and whether food is being served can all affect consumption.

Rather than simply calculating a fixed number of drinks per guest, an experienced bar company can help you estimate what is realistic for your particular event.

Open Bar vs Paying Per Drink

An open bar isn't the only way to provide drinks at a wedding.

Some couples choose to pay for every drink consumed, while others provide a limited number of drinks per guest or offer an open bar for part of the event.

There are advantages to each approach.

An open bar provides a simple experience for guests because they don't need to worry about carrying money or cards around. It also allows the couple to decide exactly what is included and gives everyone the same access to the drinks available.

For some weddings, however, a limited bar or drinks package may be more appropriate.

Does an Open Bar Include the Bar Itself?

This is an important question to ask when comparing quotes.

"Open bar" describes how guests pay for drinks, but it doesn't necessarily tell you what physical bar service is included.

A wedding package may include the mobile bar hire London service itself, professional bartenders, glassware, ice, mixers, setup and pack down. Another supplier may price some of these elements separately.

When comparing quotes, make sure you're comparing like-for-like services rather than simply looking at the drinks cost.

Can You Have an Open Cocktail Bar?

Yes. An open bar doesn't have to mean unlimited beer and wine.

Many couples choose to offer a cocktail bar with a smaller selection of drinks specifically chosen for the wedding.

For example, you might have a signature cocktail named after the couple, a classic Margarita or Mojito, alongside wine, beer and soft drinks.

A carefully chosen cocktail menu can actually make an open bar easier to manage because the bartenders can prepare drinks efficiently and keep the service moving during busy periods.

How to Keep an Open Bar Affordable

If you're working with a wedding budget, there are several ways to control the cost without compromising the guest experience.

Choosing a focused drinks menu can be more cost-effective than offering every possible spirit and cocktail.

You could also offer the open bar for a specific period rather than the entire wedding, or provide cocktails during the reception before switching to a simpler bar later in the evening.

Most importantly, consider the number of guests and expected drink volume together. Larger events can often achieve much better value per person because the cost of the professional setup is spread across a greater number of drinks.

How Much Is an Open Bar at a Wedding?

Ultimately, How Much Is an Open Bar at a Wedding? depends on your guest numbers, the length of the service, the drinks you choose, your venue and the expected volume of drinks. A professional mobile bar can tailor the service around your wedding rather than forcing you into a standard package, and larger events can often benefit from significantly better value per guest.
