How to Hire a Bartender for a Party in St. Louis
Revised November 3, 2026
How to hire a bartender for a private party?
Set your guest count and a firm start and end time, then shortlist two or three bartenders to interview. Tell each one plainly whether they bring the bar, tools, ice and glassware or just themselves, and who buys the alcohol. Confirm liquor-liability coverage and the rules at your venue. Then compare what each is prepared to deliver.
Keep reading ↓It’s 8:14 and the ice is gone. Not low. Gone. The cooler at the end of the folding table holds four inches of gray water with one bottle of tonic bobbing in it, and eleven people are standing in a line that bends around the deck rail. At the head of that line is your cousin, who volunteered to “handle drinks” at three o’clock, has not eaten since, has not sat down, and has not spoken to his own wife in ninety minutes.
He isn’t bartending. He’s trapped.
That trapped-cousin problem is what a hired bartender actually solves, and it’s why the money question is harder than it first looks. You’re not paying somebody to know how to build an old fashioned. You’re paying for the part of a party that breaks first: ice, glassware, the line, the one guest who needs watching, and the cleanup at midnight that nobody else volunteers for. What that runs in the St. Louis metro depends on a short list of things, and hardly any of them are the drinks.

Notice what came first there. Not the rate. Three numbers: how many people, what time the bar opens, what time it closes. Every quote you get back is built on those three, and hosts who call without them get vague answers and then feel misled later. Write them down before you send a single message. It takes four minutes and it changes every conversation you have after.
The second thing to settle is scope, and this is where most of the surprises live. Some bartenders arrive with a portable bar, shakers, jiggers, strainers, a speed rail, coolers, bagged ice, garnish cut and boxed, and racks of rented glassware. Some arrive with a bottle opener and expect your kitchen to be the bar. Both are legitimate businesses. They are wildly different products, and comparing their hourly rates as though they’re the same thing is how hosts end up driving to a store at 4pm on the day of their own graduation party.
Then get quotes. Plural. Rates in this metro move with guest count, total hours, the date on the calendar, how far someone has to drive, and whether the job is a two-person setup or a one-person setup. Anybody who hands you a firm number before asking about those things is guessing, and their guess will get revised.
How many bartenders do you actually need?
One bartender per fifty guests is the working rule most event staff use for a standard open bar, and it holds up well in practice. Fifty is not a ceiling on what a good bartender can physically pour. It’s the point where the line stops moving and people start drifting toward the kitchen to make their own.
So a backyard fiftieth in Creve Coeur with forty-five people gets by with one. A graduation party with ninety wants two. A wedding reception with a hundred and eighty, full open bar, cocktails rather than beer and wine, is a three-person bar and probably four with support. That math is boring and it is also the single biggest thing separating a party where people talk to each other from a party where people stand in a line.
What pushes the number up
Drink complexity, mostly. A beer-wine-and-two-batched-cocktails bar moves roughly twice as fast per guest as a full cocktail bar where every order gets shaken to order. Toasts compress everything: a hundred and fifty champagne pours in eight minutes is a different job than a hundred and fifty drinks over four hours. Single-point bars back up worse than two stations placed apart. And a crowd that skews heavily toward drinkers in their twenties will order faster and more often than a family reunion with kids running around.
When you want a bar back
Somewhere north of roughly a hundred guests, the second body stops being a luxury. A bar back hauls ice, restocks bottles, runs glassware, breaks down boxes and keeps the bartender behind the bar instead of walking to a garage cooler every eleven minutes. Ask whether the person you’re interviewing brings help at your count, and whether that help is billed separately or folded in. It is one of the most common line items hosts don’t know to ask about.
What does the hourly rate usually cover?
Most private-event bartenders in the metro quote an hourly rate against a minimum number of hours, and the clock they bill is not the clock your guests see. Setup and breakdown are real labor and they get paid for. A four-hour party is generally a five-and-a-half or six-hour booking, and that gap is where hosts get startled.
Hours booked versus hours worked
Figure roughly sixty to ninety minutes of setup before your stated start: ice in tubs, bottles chilled and arranged, garnish out, glassware unboxed and wiped, a station built so nothing requires a second trip. Then thirty to sixty minutes of breakdown after last call. Somebody has to pour off the melt water, bag the bottles, wipe the surfaces and load a car. If the quote you’re reading says four hours and your party is four hours, ask where setup went. It did not disappear.
Minimums, travel and the date
Nearly everybody works against a booking minimum, often three or four hours, because a two-hour job still costs a full evening once you count loading, driving and unloading. Travel is its own line. A bartender based in the city driving out to Troy or St. Clair is spending real time on the road, and a mileage or travel charge past a certain radius is normal rather than sneaky. The calendar matters too. Saturday in May, Saturday in October, New Year’s Eve, the weekend of a big local event: those dates get quoted differently than a Thursday in February, and the good people are booked out months ahead for them.
The line items that move your total
Ask about these one at a time. Bagged ice and how much. Glassware, rented or plastic or yours. A portable bar or a table you provide. Garnish prep, which is an hour of knife work somebody is doing whether or not it shows up in writing. Mixers, juices and syrups. Batched cocktails, which cost prep time and save service time. A second station. Tubs, coolers and trash bags. Whether tip is included or left open. Each one is small. Together they can be a third of your total.
Who brings the bar, the ice and the glassware?
Depends entirely on who you hire, and it is the question that decides whether your quote is cheap or complete. A bartender who shows up with tools, ice, coolers, garnish and glassware is running a small mobile operation with real overhead. One who shows up with skills alone is charging for skills alone. Neither is wrong.
Say what you have out loud during the interview. “I have a six-foot folding table, a garage fridge, a hose in the back, and no glassware at all.” That sentence does more work than any checklist. A working bartender hears it and immediately tells you what’s missing, because they’ve stood in that exact yard forty times.
Ice is the one people underestimate every single time. Plan on something like a pound to a pound and a half per guest across an evening, more in July, and remember that ice used for chilling bottles in tubs is not ice you can put in a glass. A party for eighty in August wants a lot more bagged ice than anyone expects to buy. Melt is not a rounding error in a St. Louis backyard.
Glassware splits three ways. Real rented glass looks best and comes with a count, a delivery window and a pickup. Decent heavy plastic is cheaper, safer around a pool and completely fine for most backyard events. Your own cabinet is free until forty people are using it and nobody can find the dishwasher. Pick one on purpose. Hosts also tend to forget that a drinks station and a food station want physical separation, the same way a candy buffet in St. Louis needs its own table or it becomes a traffic jam with a spoon in it.
Does a bartender need a license in Missouri?
Missouri doesn’t issue a statewide bartender license the way a handful of states do. Alcohol here is governed through state liquor control plus local city and county ordinances, and those local rules genuinely differ across this metro. What binds you as a host comes from three places: state and local law, your venue, and insurance.
Start with the distinction that actually matters. Is alcohol being sold, or is it being served free to invited guests? A cash bar, a ticketed event, a donation jar next to the bottles: selling alcohol is a licensed activity, and a caterer or venue that sells or serves alcohol carries its own liquor license. A private host pouring free drinks for guests at their own home sits in a different place. Those two situations are not interchangeable, and the second you charge anybody anything for a drink, you have changed what you’re doing.
Local ordinance is the part nobody can answer for you in a blog post. Rules around permits, hours, public spaces, parks, rented halls and temporary events vary by municipality and by county here, and they change. Call your own city hall or county office and ask about your specific event. Ten minutes on the phone beats a guess. If you’re in a rented venue, a park shelter, a church hall or a country club, the venue’s own written policy is a second and separate layer on top.
What you can absolutely ask the bartender about is insurance and training. Liquor liability coverage, general liability, and whether they carry responsible-serving certification are all fair, normal questions, and plenty of venues require proof of coverage before they’ll let anybody pour on site. A professional will have a certificate of insurance ready and won’t be offended you asked. Somebody who gets prickly about it has told you something useful.
One rule is not negotiable and not local: Missouri’s legal drinking age is 21. A bartender worth hiring will card at a graduation party where half the guests are eighteen, will cut off a guest who needs cutting off, and will do both without making it your problem. That judgment is genuinely most of what you’re buying.
How much alcohol do you buy for your guest count?
The common planning assumption is about one drink per guest per hour for the first hour or two, then tapering, which for a hundred guests over four hours lands somewhere near three hundred to four hundred drinks total. It’s a starting point, not a promise. Your crowd, your season and your menu all bend it.
In most cases the host buys the alcohol. That’s usually the cheaper path and it keeps the bartender out of licensed-sales territory entirely. A bartender may well build your shopping list, tell you exactly how many bottles of each thing and in what sizes, and hand you a list organized by store aisle. Good ones do this without being asked. What they generally will not do is buy it and resell it to you.
Rough split to argue with: beer and wine tend to carry the bulk of consumption at family events, and a liter bottle of spirits yields somewhere around twenty to twenty-two standard pours depending on how it’s measured. Heat drives beer and anything tall and cold. A December party in a rented hall drinks differently than a June party in a yard in Madison. Limiting the bar to beer, wine and two signature cocktails cuts both the shopping list and the service time, and almost nobody complains.
Buy where you can return what you don’t open. That single habit does more for the alcohol line on your budget than any amount of arithmetic. Ask the retailer about their unopened-return policy before you load the cart, because policies differ. And build the cocktail list with your bartender, not at them. If you want something ambitious, the kind of thing you’d order at one of St. Louis’s best craft cocktail bars and speakeasies, say so early. Batching it is a completely different conversation than shaking it eighty times.
Feeding them too? What African food to order in St. Louis.
Who tips a private-event bartender?
At a hosted party where drinks are free, the host tips, and the customary range people work from is roughly 15 to 20 percent of the service total. Not the alcohol total. The service total. Some bartenders build gratuity into the quote, some leave it open, and you should know which before the day.
Ask directly during the interview. “Is gratuity included, or should I plan on it separately?” If it’s already in there, tipping again is generous rather than required. If it isn’t, put cash in an envelope the night before and hand it over at breakdown. Doing it then, rather than promising to send something later, is one of those small things that gets you the same bartender next year.
Tip jars are a whole separate decision, and it’s yours to make. Plenty of hosts ask that no jar appear at all, because a jar tells guests they should be paying for something at a party they were invited to. Others let it sit out quietly. Either way, decide it in advance instead of discovering a mason jar full of fives on your table at nine o’clock. And if you’re also tipping a bar back, say so, so the split is clear and nobody is doing awkward math in your driveway.
How do you choose between two bartenders?
Shortlist two or three people worth interviewing, then interview them and state plainly what you want: guest count, hours, whether they bring the bar, who buys the alcohol, whether you need help at that count. Then compare what each one is prepared to deliver against what you asked for. The gap is the signal, not the price.
Here’s how that plays out. You describe eighty guests, five hours, a yard with a folding table and no glassware. One bartender comes back with a staffing recommendation, an ice quantity, a note that the toast will need pre-poured champagne, a shopping list, a proof of insurance and a question about where the trash goes. The other says yes, sounds great, and gives you an hourly rate. Both may be fine at the actual job. Only one has shown you they’ve done your party before.
Questions that earn their keep in that conversation: How many events like mine have you worked this year? What do you need from me that I probably haven’t thought of? What time do you arrive and what time are you loaded out? What happens if you get sick the week of? Who handles a guest who’s had too much? That last one separates people fast.
Get the agreement in writing, however simple. Date, arrival time, service window, breakdown, guest count, headcount of staff, what they bring, what you bring, deposit, cancellation terms, gratuity. A short written note beats a long phone memory. Then let them run it. A hired bartender who has to be supervised isn’t saving you anything, and the whole point was to get you back into your own party. Rented hall, backyard, a room where the night ends at a karaoke bar in St. Louis after the toast, same principle every time.

Frequently asked questions
How much should you pay a private bartender?
There’s no single metro rate, because the number moves with guest count, total hours including setup and breakdown, travel distance, the date, and how much of the bar the bartender supplies. A person who brings tools, ice, coolers, garnish and glassware prices differently than one who brings only themselves. Get two or three quotes against the same written brief and compare scope, not just the hourly.
How many bartenders per 100 guests?
Two, as a baseline, using the common one-per-fifty guideline. Go to two plus a bar back if you’re running a full cocktail menu, serving a champagne toast, or working a venue where ice and stock live far from the bar. Beer, wine and a couple of batched cocktails can sometimes stretch further. The moment a line forms and stays, you were short.
What do you pay a bartender for a wedding?
Weddings usually cost more per hour than a backyard party, and the reasons are structural. Longer service windows, a cocktail hour and a reception, a toast that compresses two hundred pours into minutes, rented glassware, premium dates, venue insurance requirements and a larger crew. Ask specifically about the staffing plan for the toast. That single moment breaks more wedding bars than the whole rest of the night.
Do you have to have a bartender license in Missouri?
Missouri has no statewide bartender license. Alcohol is regulated through state liquor control plus local city and county ordinances, which differ across this metro, and any business selling or serving alcohol needs its own liquor license. What matters for a private host is whether alcohol is being sold, what the venue requires, and whether the bartender carries liquor liability coverage. Confirm specifics with your own city or county.
What is the 50% rule in bartending?
It isn’t a law or an industry standard. It’s bar-trade shorthand, and more than one version circulates. The reading most event planners use: assume roughly half your guests are actively drinking in any given hour when you size the bar, the ice and the staffing. Useful as a sanity check. Don’t treat it as gospel, and don’t build a shopping list on it alone.
Is $20 a good tip for a bartender?
For one drink at a bar, that’s generous. For a private event, it’s low, because event tipping runs off the service total rather than per drink. The customary range is about 15 to 20 percent of what you paid for the service. Ask upfront whether gratuity is already built into the quote so you’re not guessing at breakdown.
Who buys the alcohol, the host or the bartender?
Usually the host. It’s cheaper, and it keeps the bartender clear of licensed-sales territory. Many bartenders will write your shopping list down to bottle counts and sizes, which is worth asking for during the interview. Buy where unopened bottles can be returned, and confirm that policy before you load the cart, since it varies from retailer to retailer.
Do you need a bar back for a big party?
Past roughly a hundred guests, yes, and sooner if ice and stock are stored far from the bar. A bar back hauls ice, restocks bottles, runs glassware and keeps your bartender behind the bar instead of walking to a garage cooler every ten minutes. Ask whether help is included at your guest count or billed as a separate person.
