Cocktail Ratio Calculator – Calculate classic cocktail ingredient ratios perfectly
The cocktail ratio calculator determines classic cocktail ingredient proportions and scales recipes to your desired serving or batch size. Perfect for home bartenders and party hosts.
Choose a cocktail (Margarita, Mojito, Negroni, Old Fashioned, etc.) or enter your own recipe, and the calculator will determine exact ingredient amounts in milliliters for your chosen number of servings. Makes it easy to prepare larger batches for parties.
What is the classic Margarita ratio?
A classic Margarita is mixed in a 3:2:1 ratio — 3 parts tequila, 2 parts triple sec, and 1 part lime juice. A Negroni is exactly 1:1:1 — gin, vermouth, and Campari. An Old Fashioned is mostly bourbon (2 oz) with a few dashes of bitters and sugar as seasoning. The calculator handles ratio conversions automatically.
