How much alcohol should you buy for a wedding reception?
A practical rule is to estimate around 1 drink per drinking guest per hour for a typical reception, then add a 10% safety cushion. From there, split the total into beer, wine, and spirits based on your crowd.
This calculator does that automatically and converts servings into real shopping quantities like beer cases, wine bottles, and liquor bottles.
What this liquor calculator includes
- Total alcoholic drinks needed based on guest count and event length
- Beer estimate in cans/bottles and 24-pack cases
- Wine estimate in 750ml bottles and 12-bottle cases
- Spirits estimate in 750ml bottles and 1.75L handles
- Mixer volume estimate for cocktails
- Champagne bottles for toasts
- Ice estimate for chilling and mixed drinks
Wedding alcohol planning assumptions (and how to adjust)
1) Percentage of guests who drink
Not all invited guests drink alcohol. Many receptions land between 65% and 85% drinking guests. If your crowd includes many non-drinkers, lower this input.
2) Drinks per hour
Use 0.75 for calmer daytime receptions, 1.0 for most weddings, and 1.25 for high-energy evening parties. When in doubt, start with 1.0 and keep the 10% buffer.
3) Beer-wine-spirits split
The right mix depends on your guests and menu. A common baseline is 40% beer, 35% wine, 25% spirits. If you plan signature cocktails, increase spirits to 30% to 40%.
Quick buying guide by beverage type
Beer
One standard beer serving is 12 oz. A case of 24 generally covers 24 servings. You can mix light, craft, and non-alcoholic options for broader appeal.
Wine
One 750ml bottle serves about 5 glasses. A 12-bottle case covers roughly 60 servings. Most couples offer one red and one white, then include sparkling only for toasts.
Spirits
One 750ml bottle yields around 16 standard 1.5 oz pours. If your bar leans cocktail-heavy, stock mixers, citrus, syrups, and garnishes in proportion to expected spirit servings.
Don’t forget non-alcoholic drinks
A smooth wedding bar always includes strong non-alcoholic coverage. Plan for:
- Water stations (still + sparkling)
- Soda and tonic
- Juices and mocktail ingredients
- Coffee and tea service after dinner
Pro tips to avoid overspending
- Ask about returns: many retailers allow unopened bottle returns.
- Offer a limited cocktail menu: speeds service and reduces ingredient waste.
- Use one signature drink: elegant, memorable, and easier to forecast.
- Coordinate with caterer/bartender: they may have historical usage data.
Sample wedding bar plan (example)
For 120 guests, 5 hours, 75% drinking, and a moderate pace, your total comes out near 500 drinks after buffer. A balanced split often lands in the neighborhood of:
- 8–10 cases of beer
- 6–8 cases of wine
- 8–10 bottles of spirits (or equivalent handles)
- 20+ liters of mixers
- 150+ pounds of ice
Your exact numbers will vary by season, meal style, and guest preferences. Use the calculator results as your primary shopping list.
