How it works
Updated July 2026Classic Ratios
Memorize foundation ratios. Daiquiri = 2 oz spirit, 1 oz lime, 1 oz simple. Scale all components equally.
Daiquiri/Margarita: 2:1:1 (spirit:sweet:sour) | Old Fashioned: 2:1:2 (spirit:sugar:bitters dash)Batch Scaling
Linear scaling works for all ingredients. 20 Negronis (1:1:1): 20 oz gin, 20 oz Campari, 20 oz vermouth.
Ingredient = Single serve amount × Number of servingsDilution Factor
Pre-batch cocktails for service add 20–25% water to simulate shake/stir dilution. Pre-diluted batches serve still or over ice.
Batch dilution ≈ 20–25% water from stirring/shakingUpdated: July 2026
Example Scenarios
1:1:1 ratio at 3 oz each: 30 oz gin, 30 oz Campari, 30 oz sweet vermouth. Add 18 oz water for pre-dilution.
2 oz bourbon, 0.25 oz simple syrup, 2 dashes Angostura bitters, orange peel. Scale ratio for whiskey preference.
Classic 2:1 gin to vermouth (dry) or 5:1 (very dry). Calculate vermouth from gin volume using ratio.
FAQ
Many sours follow 2:1:1 (spirit:sweet:citrus). Negroni/Manhattan: 1:1:1 or 2:1:1. Old Fashioned: spirit with sugar and bitters. Ratios vary by classic recipe.
Scale all ingredients linearly. Add 20–25% water for dilution. Chill thoroughly. Citrus juices add fresh day-of, not in advance batch.
Yes for stirred/spirits-forward drinks served up. Not needed for drinks served over ice (dilution from ice melt).
Dash ≈ 0.03 oz (1 ml). Scale dashes linearly: 2 dashes × 30 drinks = 60 dashes ≈ 2 oz bitters.
Ratios stay constant. Only total volume changes. Exception: very large batches may need slight adjustment for perceived sweetness (dilution variance).
