Drinks to cover 100 guests over 5 hours
450
Based on 75 guests who drink, at 6 drinks each — two in the first hour while everyone arrives, then about one per hour.
| Buy | Amount | Notes |
|---|---|---|
| Beer | 180 bottles or cans | 8 cases of 24 |
| Wine | 36 bottles (5 glasses each) | 3 cases of 12 |
| Spirits | 6 bottles of 750ml | about 16 drinks per bottle at a 1.5oz pour |
| Toast sparkling | 13 bottles | one small pour for each of 100 guests |
| Mixers | 30 litres of soda, tonic and juice | roughly one litre per three spirit drinks |
| Ice | 150 lb | 1.5 lb per guest, covering chilling and serving |
| Glassware | 250 glasses | guests lose track of their glass — budget more than one each |
Buy on a returns policy where you can. Most shops take back unopened cases, so it costs nothing to round up.

Frequently asked questions
Wedding Alcohol Calculator questions
How much alcohol do I need for 100 wedding guests?
A common planning rule is roughly two drinks in the first hour and one per hour after that, for the share of guests who drink. Set your numbers above and the calculator does the rest.
How many bottles of wine are in a case?
A standard case holds twelve 750ml bottles, which pours about sixty glasses. The shopping list rounds up to whole cases so you are never short.
Is it cheaper to supply our own alcohol?
Usually yes, if your venue allows it and does not charge corkage. Compare the total here against the venue's per-person bar package before deciding.
