Frequently asked questions

Wedding Alcohol Calculator questions

How much alcohol do I need for 100 wedding guests?

A common planning rule is roughly two drinks in the first hour and one per hour after that, for the share of guests who drink. Set your numbers above and the calculator does the rest.

How many bottles of wine are in a case?

A standard case holds twelve 750ml bottles, which pours about sixty glasses. The shopping list rounds up to whole cases so you are never short.

Is it cheaper to supply our own alcohol?

Usually yes, if your venue allows it and does not charge corkage. Compare the total here against the venue's per-person bar package before deciding.
