Frequently asked questions
- How much alcohol do I need per person?
- A common planning rule is about one standard drink per guest per hour. For a four-hour party that is roughly four drinks each, though the light and heavy settings adjust this up or down. Always buy a little extra and offer water and soft drinks alongside.
- How many drinks are in a bottle of wine or spirits?
- A 750 ml bottle of wine pours about 5 glasses, and a 750 ml bottle of spirits makes about 16 cocktails at roughly 1.5 oz of alcohol each. The calculator uses these to turn your drink counts into bottles to buy, rounding up so you have enough.
- How much ice should I buy for a party?
- Plan on about 1 to 1.5 pounds of ice per guest, more in hot weather or if you are chilling cans and bottles in tubs as well as using it in drinks. The calculator uses 1.5 pounds per guest by default.
- Is this an exact figure?
- No, it is an estimate for planning. Real consumption depends on your guests, the weather, the food and how long people stay, so treat the shopping list as a sensible starting point and buy a bit extra. Please serve alcohol responsibly.
