Searches like “how much alcohol for a wedding of 100” and “of 150” are some of the most common reception questions. Here is the standard formula and how to adjust it.
The formula
Drinks = drinking guests × (2 + hours after the first).
For 100 guests over 5 hours: 100 × (2 + 4) = 600 drinks. If about 90% drink, that’s about 540.
Turn drinks into bottles
| Type | Share | Per bottle | For 540 drinks |
|---|---|---|---|
| Wine | 50% | 5 glasses | about 54 bottles |
| Beer | 20% | 1 | about 108 |
| Spirits | 30% | about 16 drinks per 750ml | about 10 bottles |
| Sparkling for a toast (optional) | — | 6–8 pours | about 13–17 bottles |
Quick reference by guest count
For a five-hour reception with about 90% of guests drinking and a 50/20/30 split of wine, beer and spirits:
| Guests | Drinks | Wine (bottles) | Beer | Spirits (750ml) |
|---|---|---|---|---|
| 50 | 270 | about 27 | about 54 | about 5 |
| 75 | 405 | about 41 | about 81 | about 8 |
| 100 | 540 | about 54 | about 108 | about 10 |
| 150 | 810 | about 81 | about 162 | about 15 |
| 200 | 1,080 | about 108 | about 216 | about 20 |
Adjust for your crowd
- More wine for dinner-focused crowds; more beer for casual parties.
- Fewer drinks for daytime and brunch weddings.
- Check whether leftovers can be returned.
- Offer water throughout, and plan safe rides home.
The drinks calculator does all of this, including your own split and non-drinkers.
Bar options
| Option | Good to know |
|---|---|
| Full open bar | Most generous; highest cost |
| Beer, wine and a signature cocktail | Generous and simpler; a popular middle ground |
| Beer and wine only | Lower cost, still welcoming |
| Cash bar | Often seen as less hospitable in the US; if budget is tight, a limited open bar is usually kinder |
| Dry wedding | Entirely fine — plan excellent mocktails, coffee and dessert |
