One drink per guest per hour

The planning rule the trade uses is one drink per drinking guest per hour. For 100 drinking guests over five hours that is about 500 drinks. Many hosts add a little for the first hour, when people arrive thirsty, which the buffer covers.

Split those drinks across types: roughly half beer, a third wine, and the rest spirits is a safe default for a mixed crowd. A 750 ml wine bottle pours about five glasses and a bottle of spirits makes about sixteen cocktails, which is how the calculator converts drinks into bottles to buy.

Account for non-drinkers and water

Set the share of guests who drink alcohol so you are not buying for the whole room. The remaining guests still need soft drinks, and everyone needs water, which the calculator adds automatically.

If you have a signature cocktail, plan its spirit separately and treat it as part of the spirits share rather than on top of it, so you do not double-count.

Buy on return where you can

Many retailers let you return unopened bottles, so buying a little long on wine and spirits is low risk; beer and anything chilled is harder to return, so size those closer to the estimate.

Do not forget ice, roughly one to one and a half pounds per guest across the event, and mixers if you are serving cocktails. Copy the list and hand the bar portion to whoever is running drinks.

Common questions

How much wine for a wedding of 100?
If about a third of alcoholic drinks are wine and you serve 100 drinking guests for five hours, that is roughly 150 glasses, or about 30 bottles. The calculator gives the exact split for your numbers.
Should I offer an open bar or limited bar?
A beer-and-wine bar covers most weddings at lower cost and is simpler to staff. Set the calculator to beer and wine only and it drops spirits from the plan and the cost.
How much ice do I need?
Plan about one to one and a half pounds of ice per guest for chilling and serving across the event, more in hot weather. Buy it the morning of.
