Formula:
Our Wedding Alcohol Calculator uses a simple, adaptable estimation method:
1. Determine Total Drinkers:
Total Drinkers = Number of Guests × (% of Guests Drinking Alcohol / 100)
2. Estimate Total Drinks:
Estimated Drinks Per Drinker Per Hour varies based on your selected "Drinker Intensity" (Light, Moderate, Heavy).
Total Drinks = Total Drinkers × Estimated Drinks Per Drinker Per Hour × Event Duration (hours)
3. Distribute by Preference & Convert:
Total drinks are then distributed based on your specified Beer, Wine, and Spirits ratios.
- Beer: ~12 oz bottle/can = 1 serving
- Wine: ~750ml bottle = 5 servings
- Spirits: ~750ml bottle = 17 servings (1.5 oz shots)
This provides an estimate in standard units, ensuring you have enough for your celebration!
