  • ~10% of guests are typically non-drinkers
  • Buy 10-15% extra to be safe (many retailers accept returns)
  • Plan 1 lb of ice per guest for chilling + drinks
  • Budget: ~$2/guest for mixers (soda, tonic, juice, garnishes)

How It Works

Planning your 2026 wedding bar just got easier! Our Wedding Alcohol Calculator helps you estimate the precise quantities of wine, beer, and spirits needed, ensuring your guests are happily refreshed without overspending or running dry.

We utilize a sophisticated formula considering average adult drink consumption rates (approximately 1.5 drinks per hour) adjusted for event type, guest demographics (e.g., wine vs. beer preference), and a 10% buffer for unexpected thirst. This accounts for the 2026 average cost per drink, allowing for budget-conscious planning.

Don't forget to factor in non-alcoholic options, and always overestimate slightly rather than running out. A common mistake is underestimating consumption for longer receptions; remember, a 5-hour event requires significantly more alcohol than a 2-hour cocktail hour.

Example: 100 Guests, 4-Hour Reception

  1. 1 Input: 100 adult guests, 4-hour reception, 50% wine preference, 30% beer preference, 20% spirits preference.
  2. 2 Calculation: Total drinks = 100 guests * 1.5 drinks/hour * 4 hours = 600 drinks. Wine: 600 * 0.50 = 300 drinks. Beer: 600 * 0.30 = 180 drinks. Spirits: 600 * 0.20 = 120 drinks. (Adjusted for typical bottle/keg yields).
  3. 3 Result: Approximately 60 bottles of wine (750ml), 3-4 kegs of beer (15.5 gal each), and 15-20 bottles of spirits (750ml).
  4. 4 Context: This provides a solid starting point. Consider offering a signature cocktail to streamline spirits and add a personal touch, and always have a small reserve for unexpected consumption spikes.

Frequently Asked Questions

How much alcohol do I need for a wedding of 100 guests?
For 100 guests at a 5-hour reception, plan for about 500 drinks total: roughly 200 beers, 180 glasses of wine (30-35 bottles), and 120 cocktails (10-12 bottles of spirits). Adjust based on your crowd preferences.
How many bottles of wine do I need per person at a wedding?
Plan for about 1 bottle of wine per 2 wine-drinking guests, which yields about 5 glasses. For 100 guests where 60% drink wine, that is about 30 bottles for a 5-hour reception.
How much does a wedding bar cost?
A DIY wedding bar costs $10-$20 per person for beer and wine only, or $25-$45 per person for a full open bar. A professional bartender adds $200-$400 for the event. Buying in bulk and returning unopened bottles saves money.
