Enter a recipe and how many drinks you need. Get the scaled amounts, the exact dilution water to add, the total volume, and the final ABV.
Skip the typing — Dram does this on any recipe you find online, in one click.
Add Dram to Chrome — freeBatching means pre-mixing one big container of a cocktail instead of building each drink to order. It is the only sane way to serve a crowd, but you cannot just multiply the recipe by the number of guests and stop there. Two things trip people up: dilution and volume.
A drink built over ice ends up roughly 10–25% water by the time it is served, depending on how it is mixed. This calculator uses the standard bartending estimates: about 15% for stirred drinks like a Negroni or Manhattan, 22% for shaken drinks like a Margarita or Daiquiri, and about 10% for built drinks served over fresh ice. The water figure above is added on top of your scaled liquid, then everything is measured for total volume and final strength.
A stirred, spirit-forward drink can land near 30% ABV even after dilution, while a shaken sour with citrus and syrup sits much lower. Knowing the number helps you judge how strong the batch will drink and how much ice or water to plan for on the day. The estimate here uses typical strengths for common spirits and liqueurs, so treat it as a close guide rather than a lab reading.
Yes. A pre-batched cocktail has not touched ice yet, so it is missing the water a fresh drink would gain while being stirred or shaken. Add the dilution water shown above before serving, or serve the batch over plenty of ice and let it dilute in the glass.
Spirit-only batches (a Negroni or Manhattan, no citrus) keep for weeks in the fridge. Anything with fresh citrus or dairy is best mixed within a day, since lime and lemon juice turn dull after about 24 hours.
At a 60ml (2oz) pour, a 750ml bottle holds about 12 drinks of a single spirit. In a mixed cocktail the count depends on the whole recipe, which is why the calculator totals every ingredient and the finished volume for you.
Completely. It runs in your browser, needs no sign-up, and nothing you type leaves the page. If you want the same scaling and dilution on any recipe you find while browsing, the Dram extension for Chrome and Edge is free too.
Dram spots cocktail recipes on any page, scales and batches them with dilution, and tracks the bottles you own — no copy-pasting into a calculator.
