How to batch cocktails: quantities, water and service

Start with one serving

Record each liquid ingredient and its measurement unit. Multiply each amount by the number of servings you want to make. Servings are pours, so twenty servings do not necessarily mean twenty guests.

The batch planner opens a Margarita recipe for 20 servings. Edit the recipe, packaging and serving method before generating your purchase and preparation sheets.

State the water percentage and its denominator

BatchPour uses this convention: added water = total recipe volume before dilution × chosen percentage. Include spirits, juice, syrup and other recipe liquids in that total. A liquid's ABV does not decide whether it belongs in the calculation.

For example, a mathematical recipe of 50 mL base spirit, 25 mL juice and 20 mL syrup makes 95 mL before water. At 20 servings:

Item	Batch amount
Base spirit	1,000 mL
Juice	500 mL
Syrup	400 mL
Before added water	1,900 mL
Added water at 20%	380 mL
Planned finished liquid	2,280 mL · 114 mL per serving

The 20% refers to 1,900 mL, not to the final 2,280 mL. This example verifies the arithmetic; BatchPour has not mixed or taste-tested it.

Diageo Bar Academy's batching guide describes total-volume water addition and adjusting the result. A percentage is a starting assumption, not a universal amount of water released by ice.

Choose what happens at service

• Chilled pour: choose your pre-added water, mix the planned ingredients and chill for service. Allow for any further dilution if served over ice.
• Shake or stir each serving: consider starting with 0% pre-added water, then test the actual service method. Ice will add water during preparation.
• Sparkling finish: hold sparkling liquids separately and add them at service. The recipe total includes these liquids, while the mix-now container amount excludes them.

The planner's 22% stir, 27% shake and 0% build presets are editable. Actual ice melt depends on the ingredients, ice and preparation. Fresh citrus belongs close to service; no fixed holding time is established by this calculation.

Turn the recipe into a practical prep sheet

1. Check the package size for each purchased ingredient. A 1,000 mL requirement in 750 mL bottles means two bottles and 500 mL left over.
2. Separate juice, prepared syrup and supplies from bottle purchases. If making syrup, use the mass-ratio guide and measure the cooled yield.
3. Check the mix-now liquid volume against your vessel. Leave room to mix; the liquid total is not a recommended container's brim capacity.
4. Record the per-serving pour, ingredients added at service and actual adjustments on the recipe card.

For source examples of recipe scaling and serving steps, see Diageo's batch recipe cards. The BatchPour planner keeps your chosen assumptions beside the quantities.

Common questions

How much water should I add to a batch?

Choose an added-water percentage for your recipe and serving method. BatchPour applies it to all recipe liquid before added water, including juice and syrup. Its stir 22%, shake 27% and build 0% presets are editable planning assumptions, not predictions of ice melt.

Why can a batch taste too strong or too watery?

A batch served without a planned ice step may need pre-added water. A batch that is already diluted and then shaken or stirred over ice gains more water. Check both preparation and service steps before adjusting the recipe.

When should I add citrus and sparkling ingredients?

Keep fresh citrus close to service and add sparkling ingredients at service. A planning calculator does not establish a storage duration or prove that a recipe retains its taste.
