Party Drink Calculator

This covers the half of the drinks table that usually gets forgotten. Enter the number of guests, how long the party runs, roughly what share of guests are not drinking alcohol and how many spirit drinks you expect to pour, and it returns soft drink servings split into soda and juice, bottled water, litres of mixer, bags of ice and a cup count. Every serving rule it uses is printed with the answer, so you can argue with it. Beer, wine and spirits are deliberately not estimated here, and real appetites swing with the weather and the food.
