The short answer
Batching is the bridge between a single great cocktail and serving a crowd. Done well, it preserves balance; done badly, it dulls everything it touches. The rules are the same every time: scale by ratio, keep the acid late, manage the dilution, and taste at the temperature you will actually serve. This page is the general method; the margarita, pitcher and espresso martini pages apply it drink by drink.
Ingredients
- One spirit base
- One acid (usually citrus)
- One sweetener
- Dilution, accounted for on purpose
Method
- Scale the single-serve recipe by ratio, not by guess. Write the multiplication down.
- Pre-batch spirit, liqueur and sweetener without ice; chill hard.
- Add citrus as close to service as you can.
- Taste at the diluted strength you will actually serve, and adjust sweetness last; cold dulls sweet perception.
Pro tips
- Acid drops out of balance before alcohol does. Taste a batch at serving dilution, not at full strength.
- Keep citrus and spirit separate until close to service to slow oxidation.
- Label every container with the drink, the date and the spec. Future you is pouring in the dark.
The ratio framework
Most shaken citrus cocktails resolve to the same skeleton: 2 parts spirit, 1 part acid, 0.75 parts sweetener, then dilution. A margarita, a paloma, a daiquiri and a whiskey sour are all this skeleton wearing different clothes. Batch the skeleton and you can scale any of them: multiply each part by the number of serves and you have the recipe, whether that is 10 drinks or 100.
Dilution is an ingredient
A shaken drink picks up roughly 20 to 25 percent of its volume in melted ice. When you batch and serve over ice instead of shaking each drink, you must decide where that water comes from. Two working answers: pre-dilute the batch with 20 percent cold water and serve over minimal ice, or batch at full strength and serve over plenty of ice, accepting that the drink evolves in the glass. What ruins batches is pretending the water does not exist.
What batches well, and what refuses
Batch happily: margaritas, palomas, mules, lemonades, mojitos without the muddling theater, punches, spirit-forward stirred drinks like negronis and manhattans (which batch almost indefinitely, having no citrus).
Batch badly: anything with egg white or aquafaba (the foam dies), carbonated drinks (flat within the hour; add fizz per glass instead), cream and dairy (splits and coats), and hot drinks (obvious, but people try).
Storage and shelf life
Holding time depends on the actual ingredients, recipe, handling and storage. Follow your approved procedure and product instructions, identify prepared containers and check flavor before service. Shelf-stable describes the supplied unopened mixer; it does not establish a universal storage life for a prepared cocktail.
From batching to draft
For a high-volume recipe, a supplied mixer keg is one way to reduce base preparation. Keep your chosen spirit, sign off the measured build and check the complete draft installation. Compare the process with your in-house batch using actual preparation, service, cleaning and waste records before deciding to roll it out.
The batch version
For a larger service, record recipe measures, chilled storage, preparation time, holding guidance and actual demand. A high-volume cocktail can be a useful candidate for a draft trial; a rotating or low-volume recipe may remain better suited to in-house batching.
On tap: the easier way
The supplied non-alcoholic mixer reduces repeated base preparation. Your venue still measures spirits, prepares and stores the keg, checks the installation and cleans the line. The standard 29 L finished build gives about 245 gross 4 oz pours before loss. Calculate serving cost from your mixer invoice, spirit bottle size and price, freight and measured waste; record labor separately.

What ratio should I use for batch cocktails?
Start from 2 parts spirit, 1 part citrus, 0.75 parts sweetener, then scale by the number of serves. Adjust to the specific drink from there; agave drinks usually run slightly drier.
How do I account for dilution when batching?
Either pre-dilute with about 20 percent cold water and serve over minimal ice, or batch full strength over plenty of ice. Decide on purpose; a shaken drink would have picked up 20 to 25 percent water.
How long do batched cocktails last?
Use the storage and holding instructions for the actual ingredients and recipe. Identify the batch, keep it under the approved conditions and check flavor before service. There is no single holding time that covers every cocktail.
Which cocktails batch best?
Citrus-led shaken drinks (margarita, paloma, mule, lemonade) and spirit-forward stirred drinks (negroni, manhattan). Egg white, cream and carbonation are the formats that refuse.
Can I batch cocktails for a bar rather than a party?
Yes, and most cocktail bars do. The limits show up at volume: prep labor, fridge space, citrus shelf life and spec drift across a service. That is the point where draft cocktails take over.
