Batching notes
These totals scale the single-serving spec exactly. They don't yet account for the water that shaking with ice adds. If you're batching this cocktail ahead of time in a pitcher rather than shaking each glass to order, add roughly 20 to 25% cold water or an equivalent amount of extra ice to the final mix to replace that dilution.
Frequently asked questions
How much alcohol do I need for a party of 20?
Plan for about 1 to 2 drinks per guest per hour. For 20 guests over three hours at 1.5 drinks/hour, that is roughly 90 total drinks. Pick a cocktail above, set guests to 20 and drinks per guest to the number you expect, and the calculator scales the full ingredient list.
Should I batch a cocktail ahead of time or make it to order?
Spirit-forward, stirred drinks (Old Fashioned, Manhattan) batch well since they hold up without ice contact. Citrus-forward, shaken drinks (Margarita, Daiquiri) are best batched without the dilution water and shaken to order, or batched with the extra water added upfront and served over ice.
How do I convert a batch back to single servings?
Every cocktail page has its own single-serving spec with a 1–10 servings slider, so you can check the base recipe at any scale before multiplying it out for a full party batch.
