Industry standard is 1 bartender per 50 guests. Barbacks support the bartenders by stocking, fetching ice, and managing the back of the bar so service stays fast.

How we calculated this

Real industry ratios. Not a guess.

Drinks per guest, per hour
Cocktail receptions average 1 drink per guest per hour. Seated dinners average 0.7 (paced by courses). High-energy events with dancing average 1.3. Afternoon events average 0.6. We add a 10% buffer to all estimates.
Drink mix
Full bar splits 50% beer / 25% wine / 25% liquor by drink count. Beer-and-wine-only assumes 60/40. Cocktail-forward shifts to 30% beer / 20% wine / 50% liquor.
Container conversions
One 750ml bottle of wine = 5 servings (5oz pours). One 1.75L handle of liquor = ~40 standard cocktails (1.5oz each). One case of beer = 24 bottles.
Bartender ratios
One bartender per 50 guests is the standard for full bar service. Barbacks (support staff) are added at 3+ bartenders or 100+ guests. Teams of 3+ include an on-site captain at no additional cost on Opulentt.
Note: These are starting points for planning. Adjust based on your venue, your crowd, and any preferences (e.g. wine-heavy weddings, tequila-forward events). When in doubt, round up — running out of alcohol mid-event is worse than having a few extra bottles.
FAQ

Common bar planning questions.

How much should I budget per person for alcohol?+

A reasonable starting point is $15-25 per guest for a 4-hour event with a full bar at retail prices. Costco/Total Wine pricing for 100 guests typically lands at $1,500-2,500 in alcohol. This doesn't include bartender labor — Opulentt bartenders run $50-65/hr per bartender depending on your city.

Should I serve liquor at my event?+

It depends on the crowd and the venue. Beer + wine only is simpler, cheaper, and works well for daytime, family, or work events. A full bar feels more polished and is standard for evening weddings, fundraisers, and brand launches. If you're unsure, do beer + wine plus 1-2 signature cocktails — captures most of the upside without the complexity.

What about non-alcoholic options?+

Always have non-alcoholic options on hand — sparkling water, soda, lemonade, and a non-alcoholic 'mocktail' or two. Plan for ~25% of guests to choose a non-alcoholic drink at some point during the event. Pregnant guests, designated drivers, and people pacing themselves all need this.

Can I bring my own alcohol if I hire your bartenders?+

Yes — Opulentt bartenders work with whatever alcohol you supply. We don't sell alcohol; we supply the bartenders to serve it. Your captain can review your shopping list before the event and flag anything missing (mixers, garnishes, glassware) so there are no surprises.

What if I run out of alcohol mid-event?+

It happens. The 10% buffer in this calculator helps prevent it. Worst case, your bartender or captain can run to a nearby store if it's that kind of venue — but plan to over-buy slightly. Most retailers will accept returns of unopened bottles, so the cost of having extras is much lower than the cost of running out.

Do I need glassware too?+

If your venue doesn't supply it, yes. Plan for ~2.5 glasses per guest over a 4-hour event (people set down drinks, get fresh ones). Disposable plastic ware works for casual events; rented or owned glassware is standard for weddings and brand events.
