Batch cocktail calculator

Scale a recipe by servings or volume, add measured dilution, check container capacity, and turn bottle gaps into a shopping list.

Step 1

Build the original recipe

Ingredients

Liquid, dry, counted, and to-taste units can share one recipe.

Ingredient 1

Ingredient 2

Step 2

Set the batch target

Scale batch by

Step 3

Add dilution

Dilution is added water divided by pre-dilution batch volume. The practical range in this calculator is 0% to 50%.

Step 4

Plan the containers

How the batch math works

Compatible liquid units
U.S. fluid ounces, cups, teaspoons, tablespoons, pints, quarts, gallons, centiliters, liters, and milliliters normalize to milliliters before scaling.
Servings and target volume
Serving mode divides target servings by original servings. Volume mode divides the target pre-dilution volume by the original liquid volume.
Added water convention
Added water equals pre-dilution batch volume multiplied by the dilution percentage. A 20% setting adds 200 ml to a 1,000 ml pre-dilution batch.
Containers and bottle gaps
Full fills use floor division. Each inventory gap is the required amount minus the amount you entered, with zero as the minimum.

Unit and service assumptions

Fluid units use U.S. customary conversions. A fluid ounce is 29.5735295625 ml and a U.S. cup is 236.5882365 ml.

Dry mass stays separate from liquid volume because ingredient density is unknown. Counted ingredients scale numerically, while to-taste rows remain qualitative.

The dilution range is 0% to 50%. Taste a chilled sample before service, especially when fresh citrus, bitters, carbonation, dairy, or egg is involved.

Frequently asked questions

Multiply every ingredient by the number of servings you want divided by the servings the recipe makes, then add water for the dilution that shaking or stirring would have given each drink. Chill the batch and pour it straight into the glass.

Add the pre-dilution volume multiplied by the dilution percentage. A stirred drink served from the fridge takes about 20%, a shaken style about 25%, so 1,000 ml of pre-dilution batch takes 200 to 250 ml of water. Skip the water if you will shake or stir each drink to order.

Batch the spirits, liqueurs and syrups ahead. Add fresh citrus on the day, keep egg white and dairy for shaking to order, and top carbonated ingredients in the glass so they keep their fizz.

Dilution runs from 0% to 50% of the pre-dilution volume. Taste a chilled sample before service and adjust.
