What this tool does
A common planning rule is two drinks in the first hour and one an hour after that, which averages near the default. A 750 ml bottle pours five 150 ml glasses. Allow a glass and a half per guest because people put them down and lose them, and half a kilo of ice each — more in summer.
Formula
drinks = guests × per hour × hours
