Party batch cocktail calculator

Choose a cocktail and how many people, and get the total amounts to buy and pour. Amounts are scaled from the IBA recipe.

Shaken and stirred drinks pick up water from the ice; batching ahead means you should add about 20 to 25 percent water and chill before serving (our rule of thumb, not an IBA figure). Do not batch drinks with fresh citrus more than a few hours ahead, and keep carbonated ingredients out until serving.
