How much alcohol · by guest count

How much alcohol
for a wedding.

A stock-planning example for adults drinking alcohol over five hours at the middle setting, with a wine-led bar (60% wine, 25% beer, 15% spirits). Adjust the calculator for your group and service hours. Beer is counted in cases of 24; wine, spirits, and champagne in 750ml bottles.

These estimates assume five glasses per 750ml wine bottle, sixteen servings per 750ml spirit bottle and six toast glasses per champagne bottle. Ask your bartender to confirm pours and the ice, mixers, water and alcohol-free drinks needed for your menu and weather. Check return policies before buying extra stock.

Common questions

How much alcohol do I need for a wedding?

As an example for buying stock, 100 adults drinking alcohol over five hours at the middle setting gives 500 drinks. A wine-led mix gives 60 wine bottles, 125 beers (six cases of 24) and five 750ml spirit bottles, plus 17 toast bottles. Confirm quantities and return policies with your bartender and supplier.

How many bottles of wine per guest?

The calculator assumes five glasses from a 750ml bottle. The number of bottles depends on the adults drinking alcohol, service hours and wine share you select. Confirm serving sizes and preferences with your bartender.

How much does the crowd setting change?

The three stock-planning settings use 0.75, 1 or 1.4 servings per adult drinking alcohol per hour. For 100 adults over five hours, that gives 375, 500 or 700 servings before the toast. These are purchasing assumptions, not advice on how much anyone should drink.

What about ice, mixers, and glassware?

Ask the bartender for quantities based on your drinks menu, weather, refrigeration and service setup. Ice, mixers, water, alcohol-free drinks, glassware and staffing are separate from the bottle counts here.

Is the calculator accurate for a destination wedding?

The calculator assumes 750ml wine and spirit bottles, five wine glasses or 16 spirit servings per bottle, and 24 beers per case. Actual pours, bottle sizes, corkage and return policies vary. Confirm them with your venue and local supplier.
