What does this tool do?
Batching a cocktail multiplies each ingredient by the number of drinks, then adds a little water for the dilution that shaking or stirring would normally provide. Mixing the batch ahead and chilling it makes serving faster and more consistent.
The Formula
Batch = drinks × (spirit + mixer) × (1 + dilution %); dilution water = batch − spirit − mixerFrequently Asked Questions
How much dilution should I allow?
Shaken drinks typically gain 20–25% water from ice; stirred drinks gain roughly 15–20%. If you serve over fresh ice, use the lower end because the ice will keep diluting the drink.
Can I make a non-alcoholic version?
Yes. Set the spirit to zero and increase the mixer, or use a non-alcoholic spirit. Keep it clearly labelled and separate from the alcoholic batch.
