Fifty guests is the size where guessing stops working. It’s too big to run to the store mid-party, and big enough that overbuying wastes real money. The good news: the math is simple once you know the rule.
Quick answer: For a 4-hour party with 50 guests, plan about 250 drinks. That’s roughly 5 cases of beer, 18 bottles of wine and 5 bottles (750 ml) of liquor, based on a 40% beer, 35% wine and 25% liquor split. Add mixers, 50 to 100 pounds of ice, and 8 to 9 bottles of sparkling wine if you’re doing a toast.
Below you’ll find the full shopping list for parties from 2 to 5 hours, how to adjust it for a wine-loving crowd, a cocktail-focused party or a beer-and-wine-only bar, and how many bartenders 50 guests really need.
The Formula: How Many Drinks 50 Guests Will Have
Event pros use the 2+1 rule: plan 2 drinks per guest in the first hour, then 1 drink per guest for each hour after that. Guests arrive thirsty and drink fastest in the first hour, then settle into about one drink an hour. For 50 guests, that works out to:
- 2-hour party: 3 drinks each = 150 drinks
- 3-hour party: 4 drinks each = 200 drinks
- 4-hour party: 5 drinks each = 250 drinks
- 5-hour party: 6 drinks each = 300 drinks
Then turn drinks into bottles using standard pours:
- Beer: 1 can or bottle (12 oz) = 1 drink, and a case of 24 covers 24 drinks.
- Wine: a 750 ml bottle pours about 5 glasses (5 oz each).
- Liquor: a 750 ml bottle makes about 14 cocktails at a 1.5-oz pour, allowing for a little spillage.
Our guide to how many drinks per person explains the rule in more depth, including how to plan separate phases like a cocktail hour followed by a seated dinner.
Alcohol Shopping List for 50 Guests
This list uses a balanced split of 40% beer, 35% wine and 25% liquor, with every amount rounded up to a full case or bottle.
| Party length | Total drinks | Beer (24-can cases) | Wine (750 ml bottles) | Liquor (750 ml bottles) |
| 2 hours | 150 | 3 | 11 | 3 |
| 3 hours | 200 | 4 | 14 | 4 |
| 4 hours | 250 | 5 | 18 | 5 |
| 5 hours | 300 | 5 | 21 | 6 |
Adjust for guests who don’t drink
The table assumes all 50 guests drink. At most parties, roughly a quarter to a third won’t drink alcohol or will drink very little. If you expect about 35 drinkers at a 4-hour party, plan around 175 drinks instead: about 3 cases of beer, 13 bottles of wine and 4 bottles of liquor. Put the savings toward good non-alcoholic options.
Push the numbers up or down
- Hot weather or an outdoor party: guests drink more, especially beer. Add a case.
- A sit-down dinner: food slows drinking, so the later hours run lighter.
- A daytime event: brunches, showers and afternoon parties often run about 30% lower.
- A younger crowd: plan toward the top of the range.
- Always round up. Running out is the mistake guests remember. Unopened bottles keep, and many stores take back unopened bottles, depending on state law and store policy.
Adjust the List for Your Crowd
The right split depends on your event. Here’s how the same 4-hour party for 50 guests (250 drinks) changes by crowd type:
| Party type | Split (beer / wine / liquor) | Beer (cases) | Wine (bottles) | Liquor (750 ml bottles) |
| Backyard party or birthday | 50 / 30 / 20 | 6 | 15 | 4 |
| Dinner party or seated reception | 30 / 50 / 20 | 4 | 25 | 4 |
| Cocktail party | 20 / 30 / 50 | 3 | 15 | 9 |
| Beer and wine only | 50 / 50 / 0 | 6 | 25 | 0 |
How many bottles of wine for 50 guests?
Wine drinkers usually split about evenly between red and white, though warm-weather and outdoor parties lean toward white and rosé. With the balanced split, 18 bottles for a 4-hour party works out to about 8 red, 8 white and 2 rosé or sparkling. If wine is the main drink, as at a dinner party, plan closer to 25 bottles.
How much liquor for 50 guests?
Five 750 ml bottles cover a balanced 4-hour party. Spread them across two or three spirits, such as vodka, tequila and whiskey, rather than stocking a full bar. If you’re serving one signature cocktail, put most of the liquor budget behind that spirit. A cocktail-focused party needs about 9 bottles.
How much beer for 50 guests?
Five cases (120 cans or bottles) cover a balanced 4-hour party. Mix a light lager with one craft option, such as an IPA or a seasonal beer. Bump it to 6 cases for a backyard party or a hot day.
Don’t Forget the Extras
Alcohol is only part of the shopping list. For 50 guests at a 4-hour party, also plan for:
- Mixers: about 2 to 3 liters of soda, tonic or juice per bottle of liquor, so 10 to 15 liters for 5 bottles.
- Citrus and garnishes: about 15 to 20 limes and lemons for 60-plus cocktails, plus any herbs or fruit your signature drink needs.
- Ice: about 1 pound per guest for drinks, plus another pound per guest if you’re chilling beer and wine in coolers. That’s 50 to 100 pounds for 50 guests. Our party ice guide covers where to buy it and how to keep it frozen.
- Champagne toast: one glass per guest. A 750 ml bottle pours about 6 flutes, so buy 8 to 9 bottles for 50 guests.
- Non-alcoholic drinks: plan 2 to 3 servings per non-drinking guest, plus water for everyone. A batched mocktail or sparkling lemonade feels far more welcoming than a soda can.
- Cups and napkins: guests swap glasses often, so plan about 3 cups and 4 napkins per guest, or 150 cups and 200 napkins for 50 guests.
What It Costs to Stock a Bar for 50 Guests
Here’s a sample budget for the balanced 4-hour list, using mid-range retail prices. Prices vary by state and brand, so treat this as a starting point.
| Item | Amount | Estimated cost |
| Beer (about $30 per case) | 5 cases | $150 |
| Wine (about $12 per bottle) | 18 bottles | $216 |
| Liquor (about $25 per 750 ml bottle) | 5 bottles | $125 |
| Mixers and garnishes | 10–15 liters plus citrus | about $60 |
| Ice | 50–100 lb | about $25 |
| Total | about $575 |
That’s roughly $11 to $12 per guest. Choosing well spirits over top-shelf, or a beer-and-wine bar, brings it down further.
How Many Bartenders for 50 Guests?
One experienced bartender can serve about 50 to 75 guests at a beer, wine and simple-cocktail bar. For 50 guests, one bartender is usually enough. Add a second bartender if you’re serving made-to-order cocktails, expect a rush when guests arrive, or have a hard stop for a toast. Our guide to bartenders per guest breaks down when to add staff.
The Cocktail Crew provides licensed, insured bartenders for private event bartending in ten cities. Rates start at $75 to $85 per hour, depending on location, with additional bartenders at a lower hourly rate. Gratuity isn’t included, a booking fee applies, and travel charges may apply outside our standard service area. You supply the alcohol and ice, we send a simple shopping list ahead of time, and mixer packages are available as an add-on. Your bartender arrives early, sets up a full bar and pours measured drinks all night, which also helps your shopping list go further.
