How do I scale a cocktail recipe for a crowd?

Multiply every ingredient in a single drink by the number of servings you need. This calculator does that for you the moment you enter the recipe and a serving count, so a two-ounce pour across twelve drinks becomes twenty-four ounces without any mental arithmetic, and it keeps the ratios between spirits, sweeteners and juices exactly right.

Why is there a dilution setting?

When you make a single cocktail you shake or stir it over ice, which melts and adds water that softens the drink. A batch made ahead skips that step, so adding roughly twenty to twenty-five percent water reproduces the same dilution and strength. It is optional and defaults to zero, so you only add water if you are pre-batching.

What units can I use?

You can work in ounces, millilitres, centilitres or parts. Parts is handy when you only care about the ratio and want to decide the actual glass size later. Whatever unit you choose, every ingredient and the total volume are reported in the same unit so the numbers stay consistent.

How do I know how big a container I need?

The calculator adds up every scaled ingredient, plus any dilution water, into a total batch volume. Compare that figure to your pitcher, dispenser or punch bowl capacity before you start mixing, and leave a little headroom if you plan to serve over ice.

From one drink to a whole party

Making cocktails one at a time is fine for two people and miserable for twenty. Batching lets you mix a pitcher or dispenser ahead of time so you can actually enjoy the party. The tricky part is keeping the ratios right and remembering the water that ice would normally add. This scaler handles both — enter a single-drink recipe and a serving count, and every ingredient scales up in one step.

Get the dilution right

A cocktail shaken or stirred over ice picks up water that rounds off the edges and brings it to drinking strength. A batch poured straight from the fridge has none of that, so it tastes sharper and stronger than the same recipe served fresh. Setting the dilution to around twenty to twenty-five percent water adds back that missing melt, so your batch tastes like the drink you tested rather than a rocket-fuel version of it.

Plan the vessel and the shopping

Because the tool totals the whole batch volume, you can check it against the pitcher, drinks dispenser or punch bowl you plan to use before you commit. It also makes the shopping list obvious — if the batch needs twenty-four ounces of a spirit, you know exactly how much of each bottle to buy rather than guessing and running short halfway through the evening.
