Cocktail Ratio Calculator

How to Use This Tool

Follow these simple steps to calculate your cocktail ratios:

1. Enter the amount of base spirit you want per serving, and select the unit (oz, ml, or cl).
2. Set the number of servings you’re preparing for (default is 1).
3. Choose a preset cocktail ratio from the dropdown, or select “Custom Ratio” to input your own proportions.
4. Click the “Calculate Ratios” button to see a detailed breakdown of ingredient amounts, total volume, and glass recommendations.
5. Use the “Reset” button to clear all inputs and start over, or “Copy Results” to save your calculations to your clipboard.

Formula and Logic

This calculator uses proportional ratio math to scale cocktail recipes accurately:

• Ingredient amounts are calculated by multiplying the base spirit amount by the ratio of each ingredient to the base spirit.
• Total volume per serving is the sum of all ingredient amounts for one drink.
• Batch totals are calculated by multiplying per-serving amounts by the number of servings.
• Unit conversions use standard measurements: 1 oz = 29.57 ml, 1 cl = 10 ml.

For preset ratios, we use industry-standard proportions for common cocktail styles. Custom ratios let you input any base:modifier:mixer proportion to fit your own recipes.

Practical Notes

These tips will help you get the most out of your cocktail calculations for everyday home use:

• Always measure ingredients using a jigger or digital scale for consistent results, especially when scaling to large batches.
• Chill glassware and ingredients ahead of time to reduce dilution from melting ice when serving.
• For batch prepping, multiply all ingredient amounts by the number of servings, then store in a sealed container in the fridge for up to 24 hours.
• Adjust ratios to taste: if a drink is too strong, increase the mixer ratio; if too sweet, reduce the modifier ratio.
• Common unit conversions for home cooks: 1.5 oz = 44 ml, 2 oz = 59 ml, 3 oz = 89 ml.

Why This Tool Is Useful

Home bartenders and party hosts save time and reduce waste with precise ratio calculations:

• Avoid over-pouring or under-flavoring drinks when scaling recipes for parties or events.
• Experiment with custom recipes without guessing ingredient proportions.
• Quickly convert between metric and imperial units for international recipes.
• Get glass recommendations to ensure your drinks are served in the proper vessels for optimal flavor and presentation.

Frequently Asked Questions

What if my cocktail has more than three ingredients?

This calculator focuses on the three core components (base spirit, modifier, mixer) that make up most standard cocktails. For drinks with additional ingredients like bitters or garnishes, add them in small dashes (0.1-0.25 oz per serving) after calculating your base ratios.

Can I use this for non-alcoholic mocktails?

Yes! Simply use a non-alcoholic base spirit (like seedlip or fruit juice) as your base, and adjust the modifier and mixer ratios to fit your mocktail recipe.

How do I adjust for ice dilution?

Standard cocktail ratios assume 10-15% dilution from stirred or shaken ice. If you prefer stronger drinks, reduce the mixer ratio by 0.5 parts per serving, or add a small amount of water to your batch to account for dilution ahead of time.

Additional Guidance

For best results when using this calculator:

• Start with small test batches (1-2 servings) when trying new custom ratios to avoid wasting ingredients.
• Label batched cocktails with the recipe name, date, and total volume to keep your fridge organized.
• Use the copy-to-clipboard feature to save your calculations to a notes app or share them with friends helping with party prep.
• Check the recommended glass type to ensure you have enough proper glassware before prepping large batches.
