Your complete bartender staffing guide for stress-free events

Your complete bartender staffing guide for stress-free events

Imagine this: the line at the bar snakes across the room, guests start getting restless, and the two overwhelmed bartenders can’t keep up. The ice is running low. Your carefully planned event is quickly turning into a thirsty disaster.

After many years in the industry, trust me — I’ve seen it happen more times than I can count.
Most event planners get bartender staffing wrong. They either hire too few people, bring on inexperienced staff, or don’t match bartenders to the event’s specific needs.

This guide gives you the exact playbook: how many bartenders you’ll need, where to find the best ones, the right questions to ask, and how to make sure they deliver when it counts.

What you need to know before hiring event bartending services

Bartender staffing isn’t just about filling a role — it’s about making sure every part of your event runs smoothly, from the first drink poured to the last call. 

Before you start Googling "best bartenders near me," get clear on a few important details. Planning ahead means fewer surprises — and a much better party.

Match your bartenders to your event style

Start with the vibe. No point hiring tuxedoed mixologists for a barefoot beach bash—or a laid-back local for a black-tie gala. Match the energy of your event to the right bar team, and you’ve already won half the battle.

Do your research to find the dream team

Now that you’ve got the basics down, it’s time to start with a bit of light detective work. Scroll through reviews, peek at Instagram feeds, and ask your party-throwing friends who they hired. You’ll learn a lot more from someone’s real-world experience than a glossy website.

Next, reach out and book a consultation. Most bartending services will happily offer a free chat to go over the basics. Be ready to share your event date, guest count, and the kind of drinks you want to serve. If you’ve got any special requests, like a signature cocktail or a no-alcohol zone—they’ll want to know that too.

Then comes the money talk. Basic service sits around $30–$35 per hour per bartender. But if you’re looking for cocktail-making flair or fancy drink menus, expect to spend closer to $56/hour. Some packages include extras like mixers, garnishes, or glassware, so ask what's included

Essential questions to ask before hiring bartender staff

Before you sign on the dotted line, make sure you ask the right questions — the kind that show you who the seasoned pros are:

• Proper payment
  As the old saying goes, you get what you pay for. Are your bartenders being properly paid by the staffing company? The London living wage is currently set at a minimum of £13.85 per hour, but expect to pay more for experienced staff.
  
• Experience matters
  Have they staffed events like yours before? A bartender who excels at gallery openings might not be ready for your disco-themed hen do.
  
• Menu creativity
  Can they create a drink menu that fits your theme? Can they whip up impressive mocktails for non-drinkers?
  
• Speed and service
  How many drinks can they serve in an hour? (A good range is 60–90.)
  
• Licenses and insurance
  Make sure they’re properly licensed and insured — boring, but essential.
  
• Equipment check
  Will they bring everything needed — like shakers, strainers, garnishes — or will you be stuck running out for supplies?
  
• Staffing recommendations
  A professional should confidently tell you how many bartenders you’ll need based on your event size and format.

How to calculate bartender staffing for different events 

Figuring out how many bartenders you need can make the difference between a smooth, high-energy event and one where guests spend half the night waiting in line.

The right bartender-to-guest ratio depends on the type of event you're hosting, the drinks you're serving, and the pace you want to set. Here's how to calculate it correctly.

Start with your guest count 

Think of your guest count as your drink-demand forecast. A good rule of thumb? One bartender for every 50–75 guests, depending on how complex your cocktail menu is. That keeps lines short, service snappy, and the vibe alive. Let’s say you're expecting 200 thirsty partygoers. Jot down 3 to 4 bartenders as your starting point. 

Bartenders alone aren't the whole picture. It's always best to support the bar with floor service staff if possible. That way staff can tray-serve and top up drinks to avoid guests having to queue in line for every refreshment. 

Factor in drink complexity 

If you’re sticking to beer and wine, you can stretch the ratio. One bartender per 75–100 guests will do just fine. 

But if you're going for fancy cocktails with flaming garnishes and muddled herbs, you’ll want more hands on deck—about one bartender per 50 guests. Maybe fewer. It takes time to shake up a masterpiece.

Consider the serving style 

Will drinks be passed around like canapés? Or are guests lining up at the bar like it's Friday night at the pub?

• Self-serve beer and wine = Fewer bartenders needed.
• Hosted open bar = Expect more drink orders, so add staff.
• Fancy doing with high expectations = Consider one bartender for every 40 guests to keep things polished and prompt.

The fancier the affair, the more hands you’ll want behind the bar. If you've got floor staff topping up drinks and tray serving, that takes pressure off the bartenders. But you still want to ensure enough bar staff for efficient service! Trust us, no one remembers the tablecloths, but they do remember waiting 20 minutes for a gin and tonic.

Know your menu, know your maths
Got a cocktail list? Count up the drinks and think through the prep time:

• Beer or basic mixers: 30–60 seconds.
• Mid-range cocktails (2–3 ingredients): 1–2 minutes.
• Crafty show-off drinks: 3–5 minutes each.

Average it out. If most of your drinks fall in the “takes-a-while” category, increase your bartender count accordingly.

Plan for peak times

Guests don’t sip evenly across the night. They drink in waves, like the first hour, post-ceremony, after dinner, during toasts.

Instead of overstaffing all night, consider adding a bartender just for the rush periods. Keeps things moving, saves on cost, and makes you look like a planning genius.

Think about the layout–and the weather 

• Hot day? Double the thirst — and consider extra bartenders.
  
• Large or spread-out venue? Add one bartender per bar station to avoid bottlenecks.
  
• Multi-room events? Make sure each zone is properly staffed so one area doesn’t turn into a traffic jam.

Your layout should guide how you place your bartenders — not just how many you hire.

How to tailor bartender staffing to every event 

Every event has its own rhythm — and bartender staffing needs to match it.

• Weddings: Go big. 1 bartender per 40–50 guests, especially for cocktail hour.
• Corporate events: Slower-paced — 1 per 75 guests for a full bar, 1 per 100 for beer and wine only. (Add more for holiday parties!)
  Small luxury events (under 50 guests): You could get by with one, but two bartenders offer VIP-level service.
• Outdoor festivals or fundraisers: Guests often arrive in big waves. Start strong with 1 bartender per 40–50 guests during the first hour.

Pro Tip: Heat = thirst. If your outdoor event will be blazing hot add 20–25% more bartenders than you think you’ll need. 

6 steps to hire bartender staff who get the job done 

Once you’ve got everything you need, now’s the time to hire your bartenders:

1. Get clear on what you need 

Before you go on a hiring spree, get crystal clear on what you actually need. This isn’t the time for vague wishes like “someone good with drinks.” 

Do you want a cocktail wizard? A wine whisperer? A beer-pouring ninja? Jot it all down. Trust us, a solid list of must-haves or certifications now will save you hours of faffing later.

2. Check for certifications

Depending on where your event is, your bartenders might need specific certifications. Think ServSafe, TIPS, or local alcohol permits. These mean they actually know the rules, can spot a tipsy uncle from ten paces, and won’t serve your 17-year-old cousin a whisky sour. Double-check your local laws so you don’t get hit with a surprise fine—or worse, no booze at your own bash.

3. Look for experience and fit 

Of course, you’ll want someone who knows what they’re doing, but also someone who fits the tone of your event.

• Laid-back garden party? You need someone calm and personable.
• High-energy nightclub-style bash? You’ll want someone fast and dynamic.

A bartender used to busy nightclubs might not be the best match for a slow-paced countryside wedding, and vice versa.

Also consider what drinks you’ll be offering. Cocktail-focused night? Look for a bartender with mixology skills. Wine-heavy evening? Hire someone with wine knowledge. And always value team players who can stay cool when the crowd picks up.

4. Get the word out 

Now that you’ve sorted your wishlist, it’s time to find the stars. Write a short job post that clearly explains what the event is, what you’re looking for, pay details, and how to apply. 

Share it on hospitality job boards, social media groups, or through a staffing agency if you’d prefer to hand things over. Ideally, start your search about three or four weeks in advance—just to give yourself a bit of breathing room.

5. Ask the right questions and get a demo

A quick phone chat won’t cut it. You want to see them on video or in person. How they present themselves, speak, smile… it all counts when they’re representing your event. Ask them things like:

• What’s your go-to drink to make?
• How do you handle difficult or intoxicated guests?
• Have you worked similar events before?
• How do you perform under pressure and in a team setting?

Want extra reassurance? Ask them to show off. A quick demo with your signature drink will reveal how fast, polished, and precise they really are.

And don’t forget to call their references. Ask past employers: Did they show up on time? Did they stay cool under pressure? Did guests rave about them—or complain?

6. Lock it in with a contract 

Once you’ve picked your dream team, lock it in with a proper contract. Nothing fancy, just something that clearly spells out what everyone’s responsible for. Include things like:

• Pay: Hourly rate, flat fee, tips—how much and when they’ll be paid.
• Work hours: Including setup, cleanup, and how long they’re sticking around.
• Dress code: Tuxedo chic or backyard casual?
• Duties: Mixing, pouring, restocking, wiping down the bar, you name it.
• Event policies: No serving underage guests, how to handle intoxicated ones, etc.
• Supplies: What you’re providing (ice, glasses, bar tools) and what they need to bring.
• Cancellation terms: In case someone bails or the event gets called off.
• Insurance: Who’s covering what, just in case.

If you’re hiring multiple bartenders, have a pre-event pep talk Go over the menu, schedule, and any quirks they should know (like Aunt Linda’s wine obsession or your rule against shots).

Hiring the right bar staff makes all the difference

You can’t have a great party without a great team. So plan ahead, choose wisely, and let your bartenders be the behind-the-bar heroes your event deserves.
