Wedding Bar Planning Basics
Planning the bar for a wedding reception is one of the most important logistical tasks, and also one of the most significant budget items. Alcohol typically accounts for 15-25% of the total wedding budget when providing an open bar. Getting the quantities right is essential to avoid running out during the celebration or overspending on excess inventory that goes unconsumed.
The standard industry formula estimates that each guest will consume approximately one drink per hour during the first hour, and then one drink every 45-60 minutes for subsequent hours. This rate varies based on the time of day, the crowd's drinking habits, and whether the event is formal or casual. Evening receptions tend to see higher alcohol consumption than afternoon events. The first hour also typically has higher consumption as guests arrive and settle in.
When calculating quantities, remember that not all guests drink alcohol. A reasonable estimate is that 10-20% of adult guests will be non-drinkers. Always provide attractive non-alcoholic options like sparkling water, specialty mocktails, sodas, and juice. Additionally, a champagne toast is traditional but usually requires only about half a glass per person, since many guests just take a sip and return to their preferred drink.

| Spirits | 30% | 10 bottles (750ml) | 16 drinks |
| Champagne (toast) | 1 toast | 15 bottles | 6-7 flutes |
| Non-alcoholic | 10-20% | 50+ servings | Varies |
Bar Planning Tips
- Ratio rule: For a full bar, plan for approximately 40% wine, 30% beer, and 30% spirits. For beer-and-wine-only events, shift to 60% wine and 40% beer.
- Seasonal adjustments: Summer weddings see higher beer consumption. Winter weddings lean more heavily toward wine and spirits. Adjust your ratios accordingly.
- Signature cocktails: Offering 1-2 signature cocktails instead of a full bar simplifies planning, reduces costs, and adds a personal touch. You can calculate spirits more precisely when the drink menu is limited.
- Ice matters: Plan for 1-1.5 pounds of ice per guest. This accounts for both drink service and keeping bottles chilled. Running out of ice is a common but avoidable mistake.
- Buy on consignment: Many liquor stores allow you to return unopened bottles. Over-buy slightly and return what is unused to avoid running short.
Frequently Asked Questions
How much alcohol per person at a wedding?
Plan for 1 drink per person during the first hour and 1 drink per person for every subsequent hour. For a 5-hour reception, that is approximately 5 drinks per person. Adjust downward for light-drinking crowds or daytime events, and upward for heavy-drinking crowds or late-night receptions.
How many bottles of wine for 100 guests?
For a full bar with 100 guests over 5 hours, you need approximately 35-40 bottles of wine (assuming 40% of drinks are wine). Split this roughly 50/50 between red and white, adjusted for the season (more white in summer, more red in winter). Each bottle provides about 5 glasses.
Is it cheaper to buy your own alcohol for a wedding?
Yes, buying your own alcohol is typically 30-50% cheaper than venue-provided open bar packages. A venue may charge $50-80 per person for an open bar, while self-purchased alcohol typically costs $20-35 per person. However, check your venue's policy first, as some require you to use their bar service. Also factor in bartender costs, glassware rental, and mixers when comparing.
