How much alcohol for a 145 person wedding
From the guest list to the shopping list: one hundred and forty-five people, one hundred and twenty-one drinkers, a five-hour bar, then bottles and cases.
The short answer
For 145 guests count 121 drinkers (12 under 21, 12 who do not drink). Over a five-hour reception that is 799 drinks: two in the first hour, one each hour after, plus 10 percent. A full bar is about 7 cases of wine, 10 cases of beer and 10 bottles of spirits. Beer and wine only is 8 cases of wine and 14 of beer.
With one hundred and forty-five people, buying by the case is the only way the list stays tidy. 121 drinkers over five hours is a lot of bottles if you round each line up separately, which the lists below do on purpose. Everyone still needs water and soft drinks, so 145 matters for those even when they do not drink.
The arithmetic for 145 guests
The pace is from Caterboss: two drinks per drinker in the first hour, then one an hour after. A 750 ml bottle pours 5 glasses of wine or 16 shots of spirits, from the NIAAA standard drink (5 ounces of wine, 1.5 ounces of spirits). A case of beer is 24.
- Drinkers: 145 − 12 − 12 = 121
- Hours the bar is open: 5 (cocktail hour through last call)
- Drinks each: 2 + 4 × 1 = 6
- Subtotal: 121 × 6 = 726
- Plus 10 percent: 799 drinks
Change the drinker count or the hours if your crowd is a daytime lunch, an older family side, or a late party. The table below does the hours for you.
| Hours | Drinks each | Total with buffer | Full bar to buy |
|---|---|---|---|
| 4 | 5 | 666 | 6 cases wine, 9 cases beer, 9 bottles spirits |
| 5 | 6 | 799 | 7 cases wine, 10 cases beer, 10 bottles spirits |
| 6 | 7 | 932 | 8 cases wine, 12 cases beer, 12 bottles spirits |
Shopping lists
Full bar, with 50 percent wine, 30 percent beer and 20 percent spirits:
| What | Drinks | To buy |
|---|---|---|
| Wine | 400 | 80 bottles, 7 cases |
| Beer | 240 | 10 cases |
| Spirits, 750 ml | 160 | 10 bottles |
Beer and wine only, 60 percent wine and 40 percent beer:
| What | Drinks | To buy |
|---|---|---|
| Wine | 479 | 96 bottles, 8 cases |
| Beer | 320 | 14 cases |
Rounding up to whole cases is deliberate. Running out at 9 pm costs more than a few spare bottles. Ask whether the shop takes back unopened bottles; rules differ by state.
The toast is extra
At a 3-ounce toast pour, a bottle fills 8 glasses. For 121 drinkers that is 16 bottles of sparkling wine, on top of the 799. Or skip it and let guests raise whatever is in their glass.
A venue bar package at Zola's average of about $47 a guest would be $6,815 for 145 people. Buying the bottles yourselves is cheaper per bottle only after bartenders, glasses, ice, mixers, corkage and insurance are added. Check first that the venue allows outside alcohol.
