Batch Cocktail Calculator

A cocktail calculator for batching: no arithmetic. Enter a single-drink recipe, say how many you are pouring, and get the exact amount of every bottle, the dilution water to add up front, the strength it lands at, and a shopping list.

HOW IT WORKS
- Build a recipe, or load a classic. Add ingredients with an amount (ounces in quarter steps, millilitres, or dashes for bitters) and a type, and Batch Pour fills in a sensible ABV for common spirits, liqueurs, vermouths, and mixers — all editable.
- Say how big. Scale to a number of servings, or pick the vessel you're filling: a 1 L or 1.75 L bottle, a 2 quart pitcher, a 3 L dispenser, a 5 L punch bowl, or a custom size. Batch Pour tells you how many servings fit and whether your batch fits the vessel.
- Get the pour. Every ingredient is listed in millilitres and ounces (and cups for big batches), with a running total.

DILUTION DONE RIGHT
A stirred or shaken drink picks up water from melting ice. When you batch ahead, that water has to go in up front. A simple slider adds it for you — stirred-style around 20%, shaken around 25%, over ice around 10%, or none at all — and shows the water as its own pour line.

KNOW THE STRENGTH
Batch Pour computes the finished batch's ABV from the volume and proof of everything in it, then tells you how strong each serving actually is in US standard drinks. If a serving crosses two standard drinks, it flags a strong batch so you can pour smaller or dilute more. A plain-language freezer note tells you whether a batch will stay pourable or freeze solid.

SHOPPING LIST
See exactly how many bottles of each spirit to buy — at 750 ml, 1 L, or 1.75 L — rounded up, with the leftover shown. Share the whole pour list and shopping list as text straight from the app.

SAVE YOUR PARTIES
Keep any batch — recipe, scale, and dilution — and reopen it next time. Everything is stored on your device.

TEN CLASSICS BUILT IN
Negroni, Daiquiri, Margarita, Old Fashioned, Manhattan, Whiskey Sour, Gimlet, Cosmopolitan, Paloma, and Aperol Spritz — each a canonical starting spec you can adjust to taste.
