How do I scale a cocktail recipe for a large group?

Multiply each ingredient by the number of servings. For batch cocktails, add ice water (about 25% of total volume) to account for dilution from stirring or shaking. Pre-batch everything except carbonated ingredients.

What is the standard cocktail serving size?

A standard cocktail is typically 100–150 ml (after dilution with ice). For batch party drinks, plan for about 150–200 ml per serving and 3–5 servings per person during a typical party.

How much ice do I need for a cocktail party?

Plan for approximately 0.5–1 kg of ice per person for a 3-4 hour party. This covers ice for shaking/stirring cocktails plus serving on the rocks. Ice melts fast, so err on the side of more.

How the calculator works and what it’s for▾

How the amounts scale

The cocktail calculator keeps the ratio between ingredients fixed and multiplies the quantities to the number of servings you want. That lets you turn a single-drink recipe into a batch for, say, ten guests without losing balance.

The result shows the amount needed of each ingredient along with the main steps for preparing it.

What you enter and what you get

You typically choose the cocktail you want and the number of servings. The calculator works out the ingredients so the proportions match the original recipe.

You get a shopping-list-style breakdown of the quantities and a short set of instructions to make planning the service easier.
