Cocktail Recipe Scaler | Batch Any Drink From One Serving to a Crowd

Enter a single-serve recipe, set how many drinks you want, and every ingredient plus the total volume scales at once. Add as many ingredient rows as the recipe needs and flip between ml and oz with one tap.

💡 About this tool

You found a great Negroni or Margarita spec online, the party is for fifteen, and now you are doing mental math on every line of the recipe. With a 45 ml base spirit, 15 ml liqueur, and 30 ml juice, scaling to a dozen drinks means three multiplications plus a running total in your head, and one slip throws off the whole batch.

This tool keeps the one-drink ratio fixed and rescales every line the moment you move the servings slider. Because bar recipes float between metric and US-customary measures, you can work in ml or oz and switch units without retyping anything. Drop in an oz spec straight from a US cocktail book, then toggle to ml to see the pour you actually need behind the bar.

🧐 Frequently Asked Questions

How do I enter a recipe written in "parts"? A part is just a ratio, not a fixed volume. Decide what one part equals (say 30 ml), enter every ingredient on that same basis, and the proportions hold no matter how many drinks you scale to.

What ml-to-oz figure does the tool use? One fluid ounce is about 29.57 ml, the same constant used here, so a value entered in oz keeps its ratio when you switch to ml.

Can I add more than three ingredients? Yes. Use "Add ingredient" to insert as many rows as you like, one each for syrups, soda, bitters, or garnish measures.

When I batch a big pitcher, is straight multiplication enough? For most builds, yes. But a shaken drink picks up roughly 20-25% dilution from ice, so if you are batching ahead and chilling without ice, add water to mimic that melt. Strong, low-volume ingredients like bitters do not scale cleanly either; dial them back rather than multiplying straight.

📚 Why "parts" beats fixed amounts when batching

Career bartenders almost always think in ratios rather than absolute milliliters, and batch calculators built by pros echo the same logic: lock the proportion, then multiply. The reason fresh-citrus drinks come with a warning is chemistry, not fussiness. Lime and lemon juice start losing their bright edge within hours of squeezing, so for a large batch the common move is to pre-mix spirits and sweeteners and add citrus close to service. Treat each drink as a recipe of ratios, scale the ratio, and the flavor balance survives the jump from one glass to a full pitcher.
