Wedding Drinks Calculator: How Much Wine, Champagne & Beer
A 75 cl bottle pours 6 glasses of 125 ml (7 to 8 of 100 ml). Work out champagne, wine, beer and soft drinks for your wedding from the guest count.
How many drinks to plan for a wedding or a party?
Plan on about half a bottle of wine per adult for the meal, one bottle of champagne per 6 flutes, i.e. 1 bottle for 3 guests over a 2-hour reception, and 1 litre of water per person. For 50 adults including 45 drinkers, a full 10-hour celebration needs about 25 bottles of champagne and 34 bottles of wine, 10% margin included.
How many glasses per bottle?
| Bottle | 125 ml glasses | 100 ml glasses |
|---|---|---|
| Split (20 cl) | 1.6 | 2 |
| Half bottle (37.5 cl) | 3 | 3.8 |
| Standard bottle (75 cl) | 6 | 7.5 |
| Magnum (1.5 L) | 12 | 15 |
| Jeroboam (3 L) | 24 | 30 |
Theoretical volumes, with no loss when pouring. The calculator counts 6 flutes per bottle of champagne and 5 glasses of 150 ml per bottle of wine.
Assumptions
- Drinks reception: 1 flute of champagne and 0.25 beer per drinker per hour.
- Meal: 0.6 glass of wine per hour, i.e. half a bottle over 4 hours, plus 0.25 flute per hour.
- Dancing: 0.5 beer and 0.25 glass of wine per hour.
- Servings: 6 flutes of 12.5 cl per 75 cl bottle of champagne, 5 glasses of 15 cl per bottle of wine, beer in 25 cl glasses, soft drinks and water in 20 cl glasses.
Worked example
50 adults including 5 non-drinkers, 10 children, 2-hour reception, 4-hour meal and 4-hour party, 10% margin:
- Champagne: 149 flutes, so 25 bottles.
- Wine: 169 glasses, so 34 bottles.
- Beer: 30.9 L, about 94 bottles of 33 cl.
- Soft drinks: 62.7 L; water: 66 L, i.e. 44 bottles of 1.5 L.
Standard drinks and moderation
A standard drink contains 10 g of pure alcohol. A 12.5 cl flute at 12% holds 1.2, a 15 cl glass of wine at 12.5% holds 1.5 and a 75 cl bottle at 12% about 7. Santé publique France, the French public health agency, advises no more than 2 standard drinks a day and 10 a week: provide appealing alcohol-free drinks and ways home. In French, the tool shows the notice « L'abus d'alcool est dangereux pour la santé » (alcohol abuse is dangerous to health), which French law requires in alcohol advertising.
Limits
Consumption varies with the guests' age, the season and the time of day: adjust the glasses per hour.
