Open Bar vs. Consumption Bar vs. Dry Hire: What’s the Difference?

Quick Answer: An open bar means the host pays for all drinks so guests never pay a cent, a consumption bar means the host pays only for what is actually poured, and dry hire means the host supplies the alcohol while the company provides professional bartending and service. Each model changes who buys the alcohol and how the final cost is calculated.

What Is an Open Bar?

An open bar is the classic full-hospitality option: guests drink freely and the host covers the entire tab. It is usually priced as a flat per-guest rate for a set number of hours or as a package that bundles staff, product, and equipment. The appeal is simplicity and generosity, because guests never see a price and never reach for their wallets. The trade-off is that you commit to a set cost regardless of how much your guests actually drink.

What Is a Consumption Bar?

A consumption bar, sometimes called a hosted-by-consumption or tab bar, means you only pay for the drinks that are genuinely poured. The bartender tracks what is served, and you settle up based on actual usage at the end of the night. This model can be more economical for lighter-drinking crowds, though the final total is harder to predict in advance. It rewards accuracy over generosity, so it suits hosts who want to control spend closely.

What Is Dry Hire?

Dry hire means you provide the alcohol yourself and hire the professionals to run the bar. The company supplies licensed, experienced bartenders, along with the tools, technique, and service, while you handle purchasing the liquor, beer, and wine. This often gives you the most control over selection and can reduce product markup, since you buy the alcohol directly. It does require you to estimate quantities and manage the shopping, so plan your purchases carefully.

Which Model Costs the Most?

There is no single answer, because the cheapest option depends entirely on your guests. Open bar offers predictability but you pay for capacity whether it is used or not. Consumption can save money with a moderate crowd but may cost more with heavy drinkers. Dry hire can lower product costs but shifts the buying, estimating, and leftover risk onto you. Treat these as general trade-offs rather than a quote, since your date, guest count, and drink preferences all matter.

How to Choose the Right One

Start with your guest list and your priorities. If you value a seamless, worry-free experience and predictable budgeting, an open bar is usually the easiest. If your crowd drinks moderately and you want to pay only for what is used, consumption may fit better. If you enjoy hand-picking every bottle and want maximum control, dry hire lets you do exactly that while still keeping the service professional.

Frequently Asked Questions

Is an open bar always more expensive than consumption?

Not necessarily. An open bar is more predictable, but with a lighter-drinking crowd a consumption bar can end up cheaper, while with heavy drinkers the open bar flat rate can be the better value. It depends on your specific guests.

Can I supply my own alcohol?

Yes, that is exactly what dry hire is. You purchase the alcohol and the company provides licensed bartenders and full service. This can reduce product markup, though you take on estimating quantities and doing the shopping yourself.
