Quante bottiglie di vino servono per 30 persone?

Per una festa di 4 ore con solo vino e il 10% di astemi, circa 27 bottiglie da 750 ml; con un mix di vino, birra e superalcolici circa 14.

Quanti drink a persona per una festa?

Una regola diffusa prevede 2 drink nella prima ora e 1 per ogni ora successiva: 5 a testa per una festa di 4 ore.

Quanti calici in una bottiglia di vino?

Circa 5 calici da 150 ml in una bottiglia da 750 ml.

Quanti drink in una bottiglia di superalcolici?

Circa 17 dosi da 40 ml in una bottiglia da 700 ml.

Quanto ghiaccio serve?

Circa mezzo chilo a ospite; di più se servi molti cocktail o se fa caldo.

Come gestisco gli ospiti che non bevono alcol?

Inserisci la loro quota: i loro drink diventano analcolici. Prevedi anche alternative interessanti, come cocktail analcolici.

Il calcolatore include lo spumante per il brindisi?

No: calcolalo a parte, per esempio un calice a testa.

Non è inclusa: offrila sempre in abbondanza, a parte.

È meglio comprare qualcosa in più?

Spesso sì, se puoi conservare o rendere le bottiglie avanzate: restare senza è più scomodo.

How much to buy for a party

Running out of wine halfway through the evening is a classic, but so is ending up with thirty leftover bottles. This calculator estimates how many drinks you will need from guests and length, splits them between wine, beer and spirits according to your guests' tastes and turns them into bottles, cans, litres of soft drinks and kilograms of ice.

How the calculation works

Total drinks: a common rule among event planners is about 2 drinks per person in the first hour and 1 for each hour after.
Non-drinkers: drinks for guests who do not drink alcohol become soft drinks.
Split: the other drinks are divided between wine, beer and spirits by the shares you choose.
Bottles: a 750 ml bottle of wine gives 5 glasses of 150 ml; a 700 ml bottle of spirits about 17 measures of 40 ml; each beer is one bottle or can.
Mixers and ice: 0.15 litres of mixer per spirits drink and about half a kilogram of ice per guest.

How much length matters

Party hours	Drinks per person	Drinks for 20 guests
1	2	40
2	3	60
3	4	80
4	5	100
6	7	140

People drink most in the first hour; after that the pace slows. That is why a 6-hour party does not need three times as much as a 2-hour one.

The mix changes the shopping list

30 guests, 4 hours, 10% non-drinkers (150 drinks in total):

Drinks mix	Bottles of wine	Beers	Bottles of spirits	Soft drinks and mixers (L)
Wine only	27	0	0	3.8
Mixed (50% wine, 30% beer, 20% spirits)	14	41	2	7.8
Beer party (20/70/10)	6	95	1	5.8
Cocktail party (20/20/60)	6	27	5	15.9

If you do not know your guests' tastes, a mix of everything lowers the risk of running out of someone's favourite. Buying a few extra bottles, if the shop takes returns or they keep, is easier than running short.

The reading bands

Up to 2 hours: a short party, most drinking happens at the start.
Up to 4 hours: a typical length for a dinner or a long drinks party.
Up to 6 hours: a long party, the pace slows but water and food are needed.
Over 6 hours: a very long party, check the stock halfway through.

Drinking responsibly

Always offer water and something to eat, provide appealing alcohol-free drinks for drivers too and do not push guests to drink. The calculator's estimates are amounts to have available, not to consume.

Limits of the calculator

The drinks-per-person rule is an average: it depends on guests' ages, the time of day, the food and the occasion. It does not include table water, coffee or sparkling wine for a toast: add those separately. Bottle and measure sizes vary between countries.

Frequently asked questions
