Key ideas in The Art of the Cocktail
- The 2:1:1 ratio uses 2 parts spirit to 1 part sweet and 1 part sour
- Spirit-forward ratios like 3:1 highlight the base liquor's complexity
- A standard 2 oz base requires 1 oz of syrup and 1 oz of citrus juice
- Lower modifier volumes prevent the vermouth from overpowering the spirit
- This ratio balances the bite of the spirit with acidity and sugar
- These drinks rely on stirring for texture rather than masking flavor
- Carbonation 'lengthens' a drink
- Bubbles release volatile aromatics
- Applying the 2:1:1 ratio
- Dilution lowers ABV for nuance
- Specific gravity measures density
- Identifying the sensory effect of lengthening a spirit
- Honey and agave are denser
- Heavier syrups require scanting
- Purpose of 3:1 or 4:1 ratios
- Adjusting for specific gravity
