Cocktail Ratio Scaler
Turn a parts-based cocktail recipe into exact volumes for any batch size.
Batch a cocktail without losing the ratio
Cocktail recipes are ratios — two parts spirit, one part citrus, one part sweet — and scaling them for a single drink or a whole pitcher just means keeping those proportions. This tool splits any total volume across the parts you enter.
A 2:1:1 recipe in a 180 ml serving becomes 90, 45, and 45 ml. Bump the total to 720 ml for a four-drink batch and every ingredient scales up in step.

Frequently Asked Questions
How does part scaling work?
You give each ingredient a number of parts and a total volume; the tool splits the volume across ingredients in proportion to their parts.
Can I batch for a party?
Yes — set a large total volume and every ingredient scales up while keeping the classic ratio, so a pitcher tastes like the single drink.
What is a common ratio?
Many sours follow 2:1:1 (spirit, sweet, sour); a Negroni is 1:1:1. Enter whatever the recipe calls for.
