The industry standard is 1 drink per guest for the first hour, then 0.5-1 drink per hour after. For a typical 5-hour reception with average drinkers, plan for about 4-5 drinks per guest. Light drinkers may need 3-4, while heavy drinkers might consume 5-6 drinks per guest.
A common starting point is 50% wine, 20% beer, and 30% liquor for mixed crowds. However, this varies significantly by region and guest preferences. Beer-heavy crowds might prefer 40% beer, 40% wine, 20% liquor. Upscale events often see 60% wine, 15% beer, 25% liquor.
For a champagne toast, one bottle serves about 6-8 guests (4-5 oz pours). Plan for one bottle per 6 guests to be safe. If serving champagne throughout the event, you'll need significantly more—our calculator adjusts quantities based on your champagne service choice.
A standard 750ml wine bottle provides about 5 glasses (5 oz each). If wine is 50% of your bar and guests average 4 drinks, you need roughly 0.4 bottles per person drinking wine, or about 1 bottle per 2-3 wine-drinking guests for the evening.
Yes! Plan for 10-15% extra as a buffer for variation in drinking patterns. It's better to have a bit extra than to run out. Many retailers allow returns of unopened bottles, so buying a few extra cases is low risk. Our calculations already include a modest buffer.
Always have non-alcoholic options! Plan for about 20-25% of your guest count to prefer non-alcoholic beverages at any given time. Stock water, soda, juice, and consider mocktails. This calculator focuses on alcohol, but don't forget these essentials.
Yes. This wedding alcohol calculator plans a formal reception's bar — bar types, a champagne toast, and quantities in cases, kegs, and bottles. For a casual, mixed-age gathering that also needs soda, juice, and water for kids, use our general party drink calculator instead.
