What is a standard cocktail measure?

A standard single cocktail typically uses 60ml (2oz) of spirit as the base, with 30ml of a secondary mixer or citrus. A double measure uses 50ml of spirit in UK bars. When scaling, use whatever your original recipe calls for.

How far in advance can I batch cocktails?

Spirit-only batches (like Negronis or Manhattans) can be made days ahead. Batches with citrus juice should be made no more than a few hours before serving, as the juice oxidises. Never add fizzy mixers until just before serving.

Should I adjust the recipe when batching?

Citrus can be slightly reduced (by about 10-15%) in large batches as the flavour intensifies when combined. Sugar syrups generally scale linearly. Always taste and adjust before serving.

How many cocktails does a 700ml bottle of spirit make?

Using a standard 60ml measure, a 700ml bottle makes about 11 cocktails. With a UK bar single (25ml), you get 28 measures. The calculator works this out for your specific recipe.

How do I keep batched cocktails cold?

Pre-chill all ingredients and the serving vessel. For punch-style service, use a large block of ice rather than cubes — it melts more slowly and dilutes the drink less. You can freeze water in a bundt tin or large container for an attractive ice block.

How We Calculate This

Cocktail batching is simple multiplication. Take each ingredient quantity from your single-serve recipe and multiply by the number of servings you need.

The Formula

Total ingredient = Single serve quantity x Number of servings
Bottles needed = Total spirit (ml) / 700ml (standard UK bottle)

Standard Cocktail Ratios

Spirit-forward (Old Fashioned, Negroni): 60ml spirit + 30ml modifier
Sour-style (Margarita, Whisky Sour): 60ml spirit + 30ml citrus + 15-20ml syrup
Highball (G&T, Rum & Coke): 50ml spirit + 150ml mixer
